The Essential Role of Electrolytes in Hydration
Tips for Maintaining Fluid Balance Hydration is about more than just drinking water—it's a delicate balance of chemistry in your body. Enter electrolytes, the unsung heroes of hydration. These tiny, charged particles work behind the scenes to power your body’s most vital functions, from keeping your heart beating to fueling your muscles. Drinking electrolyte rich water makes it much easier to quench your body’s thirst and provides cells and tissues with more of what they need to function optimally. People often turn to electrolytes when they’re sweating through an intense workout, recovering from illness, or navigating a hot summer day, but we also need them in the winter too. During cold winter months, the body’s thirst response diminishes because blood vessels constrict to conserve heat. This reduces the signals to drink water, even though the body still loses fluids. Regardless of season, electrolytes play a critical role in maintaining balance, energy, and health. But what are electrolytes, exactly, and why do they matter so much in hydration? In this article, we’ll cover the basics of electrolytes, explore their importance in hydration, and share practical tips to ensure you stay optimally hydrated no matter what you’re doing. Shop Fringe Electrolyte & Mineral Mix Electrolytes 101 Electrolytes are substances that dissolve in water to produce ions, which are charged particles. These ions conduct electricity, making electrolytes essential for a variety of biological and chemical processes. Common electrolytes include: Sodium (Na⁺): Vital for nerve impulses, muscle contractions, and fluid balance. Potassium (K⁺): Crucial for heart function, muscle contractions, and maintaining cell integrity. Calcium (Ca²⁺): Important for bone health, blood clotting, muscle function, and nerve signaling. Magnesium (Mg²⁺): Supports enzyme activity, muscle function, and energy production. Chloride (Cl⁻): Maintains fluid balance and aids digestion by forming stomach acid (HCl). Bicarbonate (HCO₃⁻): Helps maintain pH balance in the blood. Phosphate (PO₄³⁻): Involved in energy production and cellular function. Electrolytes are closely related to minerals because many electrolytes are, in fact, minerals. Minerals like sodium, potassium, calcium, magnesium, and chloride serve dual roles as both essential nutrients and electrolytes. Once dissolved in the body’s fluids, these minerals become electrolytes (ions) that facilitate critical processes. This is why Fringe’s electrolyte product is named “Electrolyte and Mineral Mix”! Electrolytes and Hydration Electrolytes are essential for effective hydration because they help regulate the balance of fluids in and out of cells, tissues, and organs. Water alone is not sufficient for proper hydration; it needs electrolytes to ensure that fluids are distributed and utilized efficiently within the body. Electrolytes regulate hydration in several ways: + Regulating Fluid Balance: + Increasing Cellular Water Absorption: Without proper electrolyte balance, it’s difficult for water to be properly absorbed into cells. Cells must be sufficiently hydrated to function properly, so when absorption is impaired, so is function. + Preventing Dehydration: + Replacing Fluid Loss: When you lose body fluids through things like sweating or illness it’s not just water that goes, it’s electrolytes too. So, if you want to replace the fluid that is lost, you have to consume electrolytes along with water. In simple terms, when water is consumed without electrolytes, it can disrupt the delicate balance of fluids in the body, which are a mixture of water along with a range of different ions. To be properly hydrated, you require both. Water As Nature Intended Electrolyte rich water is the way nature intended water to be. Pure H2O is a result of manufacturing, not nature. Water in nature also contains a wide range of nutrients in the form of dissolved minerals… aka electrolytes! As it travels over rocks and through the earth, minerals make their way into water. The composition of natural water varies widely and depends on the geology of the region it comes from. For example, calcium rich water can be found the mountains of Italy, while magnesium rich water is extracted from volcanic groundwater in Germany. How to Stay Optimally Hydrated Here are some practical tips to help you stay optimally hydrated: Listen to your body: Thirst is a natural indicator but can sometimes lag behind actual hydration needs, especially during intense activities. Stay ahead of your thirst by drinking 2-3 litres of fluid daily. Monitor urine color: Pale yellow indicates proper hydration, while dark yellow suggests a need for fluids. Eat electrolyte rich foods: Include naturally electrolyte-rich foods in your diet, such as bananas (potassium), dark leafy greens (magnesium), and dairy products (calcium). Use electrolyte supplements: Supplements can be used daily to enhance the electrolyte concentration of water (especially reverse osmosis water, which is totally devoid of electrolytes). Increase use whenever you have increased fluid loss, such as when exercising, spending time in the heat, or suffering from illness. Drink electrolyte solutions during the activity and afterward to rehydrate. How To Choose an Electrolyte Supplement What to look for in a product: A range of electrolytes, including including sodium, chloride, potassium, magnesium, and calcium. %DV (Daily Values) that are less than 20%; in natural water, levels will will be between 1 and 20% DV, so this is a good rule of thumb to follow. Simple, naturally derived ingredients, without added sugars or “natural flavors” Verification of purity through an unbiased chemical analysis performed by a third-party lab. Fringe Minerals and Electrolyte Mix meets all these criteria and is a great option for both adults and kids looking to support their hydration. Simply mix 1 scoop of electrolyte powder into your water, 1-2 times per day.

Light Therapy & Menopause
Menopause Menopause is the natural transition that occurs when a woman stops menstruating, which usually happens between the ages of 40 and 58. The term “transition” refers to a change from one state to another, which is a very apt descriptor for what happens during menopause. Hormonally speaking, menopause marks a shift to an entirely new hormonal milieu, which not surprisingly, can be quite challenging. Hormonal Changes During Menopause The hormonal changes that accompany menopause are dramatic. From perimenopause (the stage leading up to menopause) to post-menopause (the stage following menopause), levels of estrogen and progesterone drop to a fraction of their previous levels. This sharp decline is not linear, instead showing fluctuations that can create a whirlwind of physical and psychological symptoms. Levels of testosterone also decrease during this transition. The effects of menopause The effects of menopause on the brain and body are similarly dramatic. Although these vary widely between individuals, there are many common symptoms, including hot flashes, loss of libido, vaginal dryness, sleep issues, weight gain, dry skin, hair thinning, digestive changes, sexual dysfunction, urinary symptoms (including incontinence) and mood disturbances. Some menopausal symptoms are local, occurring mainly in the pelvic region, while others (such as hot flashes) are felt throughout the body. Similarly, some symptoms are transient while others cause persistent and long-term physical changes. The experience of menopausal symptoms is extremely common. Overall, it is estimated that 75-80% of women suffer from symptoms related to menopause, of which 20-30% are considered severe. Approximately 75% of women worldwide experience hot flashes, while 40-60% suffer from sleep issues. As many as 83% of women report experiencing vaginal dryness, often with associated pain during intercourse. Research has found that 9 in 10 women weren’t educated about menopause, and since talking about these symptoms has long been viewed as “taboo”, women often suffer menopause symptoms in silence, leaving them unable to access tools that might help to alleviate them. Improving access to supportive tools during menopause is a critical public health issue. This includes natural and alternative therapies, as well as novel tools such as light therapy. Light - including red, near infrared, and blue light – may help to alleviate several of the challenging symptoms of menopause, including sleep and mood issues, vaginal dryness and atrophy, hair loss, overactive bladder, sexual dysfunction, cognitive and digestive changes, and skin problems. Read on to learn how light therapy can be used to support women’s health during this important transitional period. Light therapy Before we can explore how light therapy can be used to support women’s health during menopause, we first need to answer the question: what is light therapy? The answer is really quite simple. Light therapy (also known as photobiomodulation) is the application of light with specific wavelengths to the body for the purposes of influencing biology. In theory, light therapy can use any wavelength of light, but the most commonly used are red, near infrared, and blue. The use of red and near infrared light is commonly referred to as “red light therapy”. All three wavelengths of light may be useful in supporting women during menopause, although red and near infrared light have the greatest utility. Research has shown that light therapy has many effects on a cellular level. Briefly, with red and/or near infrared light, the most notable observed effects include an increased production of cellular energy, reduced inflammation, decreased oxidative stress, decreased pain, increased blood flow, enhanced collagen and supportive tissue production, and improved microbiome health (gut and vagina). Blue light is mainly used to destroy pathogenic microorganisms like yeast and bacteria. Light Therapy & Menopause Given that there is such a wide range of menopausal symptoms (note that for simplicity, symptoms related to peri-, meno- and post-menopause are being considered here as “menopausal” symptoms), it is likely that the various physiological effects of light therapy will be more or less relevant for certain ones. For example, some of the changes seen during menopause – such as vaginal atrophy, dryness, and urinary incontinence - are due in part to a decrease in blood flow and loss of connective tissue in the pelvis. While specific research into using light therapy to treat these symptoms is still sparce, researchers have proposed that based on existing scientific evidence, red light therapy may alleviate these symptoms by stimulating the production of collagen and elastin, supporting bladder function, and enhancing blood flow. Many symptoms of menopause are also experienced in other states, and we can look to those conditions for clues regarding how to use light therapy to alleviate the same symptoms during menopause. This includes anxiety and depression, hair loss, sleep disturbances, acne, digestive issues, and infections. While research specific to these symptoms in menopausal women is lacking, there is clear evidence that light therapy (with red, near infrared, and/or blue light) can be helpful in other conditions, and we can extrapolate from there to the menopausal state. Based on the known physiological effects of light therapy, and the evidence of benefits in a range of clinical conditions, we propose that the use of red, near infrared, and/or blue light may help to alleviate several of the most common symptoms experienced by women during this life transition, including: Mood: Mood changes are a common experience during menopause, with many women reporting increases in anxiety and depression. Light therapy (with red and near infrared light) has been shown to reduce depressive symptoms in both humans and animals, likely due to improvements in mitochondrial function, increased brain blood flow, and decreased neuroinflammation. A 2009 clinical trial found a reduction in symptoms of depression and anxiety in as little as a single session. The effects of light therapy on mental health are so compelling that a recent systematic review concluded that it is “strongly recommended” as a treatment for moderate depressive disorder and is “recommended” for the treatment of anxiety disorder. Studies of red light therapy and depression often apply light therapy directly to the skull, while some use an intranasal approach. Cognition: Cognitive changes, such as memory loss, are also commonly experienced by women during menopause. Researchers have shown in a series of controlled clinical studies that near infrared light therapy improves cognition in young and middle-aged healthy adults when applied to the prefrontal cortex of the brain. Cognitive improvements were accompanied by changes in brain function, including increased brain blood flow. In 2019, a meta-analysis of all the research looking at the effects of light therapy (including near infrared light, or near infrared and red light in combination) found that the overall effect on cognition was positive, leading the authors to conclude that light therapy is a “cognitive-enhancing intervention in healthy individuals”. Hair Loss: Menopausal women frequently report hair loss and thinning. The ability of light therapy to induce hair growth was observed in studies conducted more than 50 years ago. Early clinical trials used primarily red light, and the effectiveness of these studies led to the development of several red light therapy devices for hair loss. Subsequent studies have shown that near infrared light also stimulates hair growth, with red and near infrared light improving hair growth in androgenetic alopecia, which is the most common type of hair loss that affects both men and women. Light impacts hair growth through effects on mitochondria, which lead to increases in the length of time the hair follicle spends in the growth phase. Overactive Bladder: Overactive bladder, involving a frequent urge to urinate, is a urinary symptom experienced during menopause. Overactive bladder often results in urinary incontinence. Although research related to light therapy and overactive bladder is limited, one study found that application of red light to the abdomen three times per day for 12 weeks resulted in a reduction of urinary incontinence as compared to a control group, suggesting a potential benefit in this condition. Skin Changes: During menopause, many women report skin changes, including acne, dryness, altered pigmentation and wrinkles. Light therapy has been widely used in spas and dermatology clinics for its effects on skin health, in addition to at-home use. Red and near infrared light is helpful in the treatment of wrinkles, psoriasis, acne, hyperpigmentation, and rosacea, while blue light is helpful in the treatment of acne. Studies show results such as smoother skin; wrinkle reduction and improved skin elasticity; and normalization of skin pigmentation. The effect of red light therapy on wrinkles can be quite dramatic, with one study showing a 30% decrease in eye wrinkle volume. Gut: Gut dysbiosis, involving changes in the gut microbiome, are common around the time of menopause. Estrogen is known to affect the gut microbiome and similarly, some of the microbes in the gut microbiome (called the estrobalome) are able to influence levels of estrogen in the body. Keeping the microbiome healthy during menopause is essential, and light therapy (with red and near infrared light) may provide some support. Animal research has shown that when red or near infrared light was applied to the abdomen of mice, the composition of the microbiome shifted to include more of a bacterial strain that is associated with better health. In humans, red and near infrared light applied to the abdomen of Parkinson’s disease patients modulated the composition of the gut microbiome, with a shift towards more “healthy” bacteria, and in a case report of a patient with breast cancer, application of near infrared light to the abdomen was associated with increased diversity of gut microbes, which is considered to be a healthy change Vaginal Dysbiosis: Similar to the gut, the vagina has a microbiome, and menopause can cause dysbiosis in this region as well. Hormone-induced dysbiosis can increase the vaginal pH and change the composition of the microbes, which is associated with bladder dysfunction and bladder pain syndrome. Light therapy, particularly with red and near infrared light, is proposed as being a positive modulator of the vaginal microbiome. There are several proposed mechanisms, including modulation of nitric oxide. Nitric oxide is important for the lactobacillus species that dominate in the vagina that are known to decrease during menopause. Sleep: As already mentioned, sleep disturbances are experienced by 40-60% of menopausal women. Light is a primary regulator of the body’s circadian rhythm, so it is not surprising that light therapy has effects on sleep. Application of red and near infrared light during wakefulness improves sleep quality in people with cognitive decline, Guillain-Barré Syndrome, fibromyalgia and stroke. When red light therapy is applied during sleep, there is an increased clearance of waste products from the brain and improved flow of cerebrospinal fluid, which are required for optimal brain health. Blue light triggers wakefulness, suppressing melatonin, so direct exposure of the eyes to blue light should be limited to daytime hours. Vaginal Infections: Vaginal infections with yeast and bacteria are more common during menopause due to the changes in estrogen, vaginal pH, and vaginal dryness that occur. In addition to their positive effects on the microbes in the gut and vagina, red and near infrared light have also been shown to have effects on pathogenic (harmful) microorganisms in the female pelvis. Red light has been shown to be helpful in treating vaginal candida, as has blue light. Specifically, blue light at 415nm (the same wavelength as in the Fringe Pelvic Wand) had the most potent anti-candida effects. Blue light has also been shown to be helpful in the treatment of vulvovaginitis. Vaginal Atrophy: Vaginal Atrophy, Dryness & Sexual Dysfunction: The loss of estrogen during menopause causes many changes to the integrity of tissues in the vagina. This results in tissue atrophy and dryness, which can cause great discomfort, especially during sex. The main structural connective tissues are collagen and elastin, which provide strength and flexibility to the vagina. These changes occur for a variety of reasons, including a decrease in blood flow which results from the loss of estrogen. Application of red and near infrared light is known to increase blood flow by increasing levels of nitric oxide. It has also been shown to increase the synthesis of collagen and other supportive connective tissue including elastin. Suggesting that red and near infrared light may help with tissue support and rejuvenation during menopause. Light Therapy Products for Menopause While early research on light therapy used primarily lasers, more recent research has found that LED’s can also be used, which also have the advantage of applying light to a larger area of the body as well as an improved safety profile. The use of LED in red/near infrared/blue light therapy devices has also greatly reduced the cost of treatment, making it something that can be done in the comfort of one’s own home. A wide range of products are available, each of which is uniquely suited to address specific needs. The four most useful light therapy products to address the symptoms of menopause are: Red light therapy panel Panels usually deliver red and near infrared light, ideally with the option to use separately or in combination. Panels can be used to treat most body parts, including the face, chest and back. They’re great for supporting sleep and mood, when light should be entering through the eyes. They can also support digestion when directed towards the skin of the abdomen, as well as the skin on the face. The Fringe Red Light Therapy Panel delivers both wavelengths of light at the same “sweet spot” intensity as the sun. shop our panel Red light therapy wraps Red Light Therapy Wraps deliver light directly to the skin and can be applied to specific body parts, such as the head and abdomen. They should also deliver both red and near infrared light. Wraps have the advantage of being cordless and very convenient to use. The Fringe Red Light Therapy Head Wrap delivers light to the head (including red and two wavelengths of near infrared light) and is ideally suited to support mood, cognition, and hair loss. The Fringe Red Light Therapy Wrap has a rectangular shape and can be applied to the abdomen to support bladder function and digestion. shop our wraps Light therapy face mask Like wraps, face masks deliver light directly to the skin but are specifically contoured to the face. Due to the antimicrobial effects of blue light, it should be included in face masks for the treatment of acne along with red and near infrared light. The Fringe Red Light Therapy Face Mask delivers all three wavelengths of light to support skin health, including acne, wrinkles, pigmentation, and more. shop the mask Light therapy pelvic wand Light therapy pelvic wands are inserted directly into the vagina, delivering light directly to the vaginal tissues that are affected by menopausal hormonal changes. The Fringe Light Therapy Wand delivers red, near infrared, and/or blue light to support blood flow and tissue rejuvenation, which may help alleviate vaginal dryness, atrophy, and sexual dysfunction. shop the wand To recap Menopause is a time of dramatic hormonal changes, which create uncomfortable symptoms for many women. Light therapy is a safe and effective tool that may be used to alleviate a wide range of menopausal symptoms in the comfort of one’s own home. Red and near infrared light provide support for symptoms including sleep and mood issues, cognitive changes, hair loss, gut and vaginal dysbiosis, skin problems, and vaginal tissue changes, while blue light may provide antimicrobial activity for menopausal acne and vaginal infections. Many different light therapy products are available - including panels, wraps, face masks, and pelvic wands – that provide light therapy support for different symptoms. Choose products that use LED lights to deliver red, infrared red, and blue light (where appropriate) at approximately the same intensity of the sun for best results.

Should I Take a Vitamin D & K Supplement?
Should I Take a Vitamin D & K Supplement? The short answer to this question is, “almost definitely, yes!” Vitamin D is the “sunshine vitamin”, and since modern humans spend so much time indoors, most of us are woefully deficient in this critically important vitamin. And while vitamin D is found in some foods, surveys of dietary intake have shown that almost everyone consumes inadequate amounts. Some people are also deficient in vitamin K, and because vitamin D and K work synergistically, they should always be taken together. Read on to learn more about how these important nutrients work in our bodies to support health, and why Fringe’s unique vitamin D and K formulation is ideally designed to meet our needs. shop fringe vitamin D & K What is vitamin D & K? Vitamins are nutrients that our bodies require in small amounts for proper growth and metabolism. Since they’re required in amounts as low as milligrams (mg) or micrograms (mcg), they’re referred to as micronutrients. This contrasts with macronutrients, which are needed in larger amounts, and include carbohydrates, proteins and lipids (fats). Vitamins D and K share the unique characteristic of being fat-soluble. The absorption of fat-soluble vitamins requires dietary fat, which makes it more complex than the absorption of water-soluble vitamins. Fat-soluble vitamins are also stored in the body, while water soluble vitamins are not. Examples of water-soluble vitamins are vitamin C and the B vitamins. What is vitamin D & K? Technically, vitamins are obtained from the diet – but as already mentioned, vitamin D is the “sunshine vitamin”. While all vitamins (including D) can be ingested through food, vitamin D is also made when the skin is exposed to the UVB light from the sun. In fact, the amount of vitamin D that can be made from the sun far exceeds the amount that is normally consumed from food sources. And since UVB rays don’t pass through windows, direct sun exposure is required for vitamin D synthesis. + More Since our modern lifestyles now have us spending up to 90% of our time indoors, dietary intake of vitamin D has become really important, with dietary supplements taking centre stage. This is because it’s hard to match the amount of vitamin D made from sun exposure from vitamin D rich foods. Thirty minutes of midday sun in the summer results in the body making around 10,000 to 20,000IU of vitamin D – which is the equivalent of consuming 50 to 100 servings of sardines, one of the best food sources of vitamin D! In the absence of sun exposure, dietary supplements are really the only way to ensure that you’re consuming sufficient vitamin D to support optimal health. Vitamin D is so important that many governments recommend, and even mandate, that it to be added to certain commonly consumed foods. When vitamin D is added to food, these are called fortified foods. In the United States, vitamin D is often added to fluid milk and other dairy products, calcium fortified fruit juices, and breakfast cereals and grains. The amount of added vitamin D is usually limited to around 100IU per serving. Clearly, this falls way short of the 10,000 to 20,000IU we generate from 30 minutes in the midday sun! In addition to fortified foods, good food sources of vitamin D include egg yolks, fatty fish (such as sardines, salmon, arctic char, herring, mackerel and rainbow trout), and beef liver. Since both fortified and natural vitamin D containing foods are usually animal-based, vegans and vegetarians are more likely to be deficient. Vitamin D2 comes from plants and fungi, while vitamin D3 comes mainly from animal sources, or less commonly, non-animal sources like lichen. Fortified food may contain either form. Like vitamin D, there is also some uniqueness in terms of how we obtain vitamin K, at least one of its two forms. The two forms of vitamin K are phylloquinones (vitamin K1) and menaquinones (vitamin K2), with K2 being produced by bacteria in the human gut. Vitamin K2 produced in the gut is absorbed into the body, and does contribute to our overall vitamin K status. However, the amount produced in insufficient to meet our needs, and some dietary intake is also required. Dietary intake of vitamin K1 comes mainly from leafy green vegetables, such as spinach, broccoli, and lettuce, as well as some oils such as canola and soybean. Vitamin K2 is mainly produced by bacteria and is found in some animal-based foods like meat, dairy, and eggs, as well as fermented foods. Since K1 in plants is tightly bound to chlorophyll, it is less bioavailable than K2, with less than 20% being absorbed into the body. What do vitamins D & K do in the body? Vitamins D and K each have critical biological functions. Here’s a look at what each one does to support our health: + Vitamin D Maintains Bone Health – Vitamin D is required for the absorption of calcium from the intestine and the mineralization of bone. Supports Muscle Strength – Vitamin D increases protein synthesis in muscle cells, thereby helping to support muscle strength. Decreases Inflammation – Vitamin D is associated with reduced inflammation, at least in part by shifting the profile of immune cells from a pro-inflammatory to an anti-inflammatory state. Regulates Immune System Function – Vitamin D is a powerful regulator of the immune system, and supports protective immunity. Protects Against Oxidative Stress – Vitamin D reduces oxidative stress, and can protect cells and tissues against oxidative damage. Supports Brain Function – Vitamin D supports brain function by protecting it against damage from inflammation and oxidative stress. This “neuroprotective action” occurs across multiple regions of the brain. + Vitamin K Maintains Bone Health – Vitamin K is required for the activation of proteins involved in bone assembly, in a process known as carboxylation. Without vitamin K, these proteins remain inactive and bone structure is compromised. Regulates Blood Clotting – Vitamin K is required for proper blood clotting, also known as coagulation. Here, vitamin K activates proteins involved in the blood clotting cascade, again via the process of carboxylation. Decreases Inflammation – Vitamin K reduces the expression of pro-inflammatory molecules, which may reduce overall inflammation. Protects Against Oxidative Stress – Vitamin K has antioxidant activity that can reduce oxidative stress by inhibiting the buildup of damaging reactive oxygen species. This is a poorly understood role of vitamin K, but it may have important health implications. Regulates Glucose & Insulin Metabolism – Vitamin K helps to regulate glycemic status, affecting both glucose and insulin metabolism. This occurs via activating effects on proteins, which are dependent on vitamin K. Regulates Immune System Function – Although a minor player relative to vitamin D, vitamin K plays a role in immune system regulation, as evidenced by its ability to affect levels of certain immune cells. How do vitamin D & K work together to support health? It’s obvious from this list that vitamin D and K overlap in some of their biological roles. And it turns out that when it comes to maintaining bone health, they actually work together as a team. Simply put, vitamin D increases the absorption of calcium from the intestines into the blood, which ideally should be delivered to bones (as well as teeth). The transfer of calcium from the blood into bones first requires vitamin D dependent synthesis of specific proteins. However, these proteins are synthesized in an inactive form. This is where vitamin K comes in... + More As previously mentioned, vitamin K activates proteins involved in bone assembly, turning these inactive proteins into active ones which can then shuttle calcium into bone. In the absence of vitamin K, calcium won’t be deposited where it should be – in the bones and teeth. When calcium isn’t deposited into the bones and teeth, it is also a problem for the cardiovascular system. If calcium builds up in the blood, which is what happens when vitamin D is present without sufficient vitamin K, this calcium gets deposited in the arteries – which can cause atherosclerosis and cardiovascular disease. So, vitamins D and K must be taken together to ensure that calcium gets deposited into bones, and not arteries, and to support optimal bone and cardiovascular health. How much vitamin D & K do I need? Vitamin D The issue of optimal vitamin D intake is highly controversial. The Institute of Medicine (which sets the dietary intake recommendations for all nutrients as recognized by the US government) recommends 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years. However, this recommendation only considers amounts needed to prevent serious bone disease, not to support optimal health. According to a scientific article published by authors including Harvard University’s Chair of Nutrition, the Institute of Medicine’s recommended intake of vitamin D “may be insufficient for important disease outcomes” and recommends a higher daily intake of up to 4,000IU per day, which has also been recommended as the “prophylactic” daily dose for most adults. Notably, total body sun exposure provides the equivalent of 10,000IU per day. The conflict over optimal vitamin D intake is based on disagreement over what target levels of blood vitamin D should be. While the Institute of Medicine states that 20ng/mL of 25-hydroxyvitamin D is sufficient, this is solely based on evidence related to bone health, which ignores the multitude of other biological roles for vitamin D. In contrast, the Endocrine Society recommends having blood levels over 30ng/mL, the American Association of Clinical Endocrinologists recommends 30-50ng/mL, and the D* Action Project suggests 40-60ng/mL. With so much controversy, how should the average person approach vitamin D supplementation? Our advice is to work with a health care provider who can monitor your blood vitamin D levels and tailor recommendations accordingly. Many people have genetic polymorphisms or medical disorders that affect their vitamin D levels, so it’s difficult to make blanket recommendations that apply to everyone. People also have different lifestyles, including time spent outdoors, and live at latitudes with varying sun exposure. Body weight is also an important factor for vitamin D recommendations, as is skin color. Working with a health care provider who can consider your unique variables and do appropriate lab work is the best way to ensure you meet your personal needs. Vitamin D needs will also vary depending on your level of seasonal sun exposure. In general, vitamin D needs go up in the winter months, especially for people who live at northern latitudes. Vitamin K The recommended intake for vitamin K is 120mcg for males and 90mcg for females aged 19 and over. Since disturbance of the gut microbiome (called dysbiosis) decreases intestinal vitamin K2 synthesis, people with gut issues may have increased dietary requirements for vitamin K. Am I at risk of vitamin D or K deficiency? There are several groups that are at an increased risk of vitamin D deficiency, including: Groups at an increased risk of vitamin K deficiency include: People taking blood thinners, which antagonize vitamin K People taking antibiotics, which destroy vitamin K producing gut bacteria (cephalosporin antibiotics may be especially problematic) People with malabsorption disorders including celiac disease, ulcerative colitis and Cystic Fibrosis, who have difficulty absorbing vitamin K People who have undergone bariatric (weight loss) surgery Can I take too much vitamin D & k? Vitamin D The main concern about excessive vitamin D intake is that it may increase calcium to dangerous levels. However, research suggests that hypercalcemia is unlikely to occur in healthy adults when blood vitamin D is below 700ng/mL, which far exceeds the recommended targets of 20 to 60ng/mL previously described. A 2007 scientific analysis of vitamin D intake and toxicity found no evidence of toxicity at an intake of 10,000IU per day and suggested that the currently recommended upper limit of 4000IU per day be revised. Subsequently, the Institute of Medicine revised their “No Observed Adverse Effect Level” to 10,000IU per day. Vitamin K There is no recognized upper limit to the amount of vitamin K1 or K2 that can be consumed. The Office of Dietary Supplements states that “no adverse effects associated with vitamin K consumption from food or supplements have been reported in humans or animals”. A synthetic form of vitamin K, called menadione, has caused toxicity in infants, but in the US this form is generally only used at present in animal food. What is the prevalence of vitamin D & K deficiencies? + Vitamin D The prevalence of vitamin D deficiency depends on what level of intake is targeted. The most conservative recommendation is the “official” recommendation from the Institute of Medicine, which as mentioned recommends 400IU for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years. Even at this low level of recommended intake, the most recent national analysis of vitamin D intake in the US found that daily intake of vitamin D from food was only 204 IU in men and 168 IU in women. This is only about a third of the Institute of Medicine recommended intake, and about 5% of the 4000IU per day recommended by other experts. At the population level, approximately 92% of men, 97% of women, and 94% of people ages 1 year and older consumed less dietary vitamin D than is estimated to meet the needs of at least half the US population. Many people do take vitamin D supplements, which increases the overall observed combined daily intake from food and supplements to 692 IU in men and 1204 IU in women, with more women taking supplements than men. Supplements are clearly helpful at increasing daily vitamin D intake, but at the current level of supplementation most people still fall well short of the higher intakes recommend by some experts. + Vitamin K The average daily intake of vitamin K according to the most recent national dietary analysis shows that men consume 118mcg and women consume 121mcg. This increases to 125mcg and 129mcg for men and women, respectively, when vitamin K supplements are also considered. These results show that most people are meeting their recommended daily intake of vitamin K intake. However, low levels of vitamin K intake have been observed in older adults, where they are associated with an increased death rate. These results show that most people are meeting their recommended daily intake of vitamin K intake. However, low levels of vitamin K intake have been observed in older adults, where they are associated with an increased death rate. Because increasing intake of vitamin D results in the synthesis of proteins that must be activated by vitamin K to prevent deposition of calcium in the arteries, vitamin K should always be supplemented along with vitamin D, regardless of whether dietary intake is sufficient. Especially considering that there is no upper limit of intake for vitamin K, combining these two vitamins in a supplementation regimen is prudent. What are the health risks of vitamin D deficiencies? Identification of health risks from having low vitamin D depends in part on what value of blood vitamin D (specifically, 25-hydroxyvitamin D) is determined as the level of deficiency. The “deficiency level” ranges from less than 12ng/mL to less than 30ng/mL, depending on which organization you follow. This will reflect a wide range of dietary and supplemental vitamin D intake. Because of this variation, the health risks of vitamin D deficiency will vary based on the deficiency level cutoff being used. + More If we broadly consider vitamin D deficiency to include anything below 30ng/mL of 25-hydroxyvitamin D, some of the associated health risks are: Loss of calcium from bones and increased risk of osteoporosis Increased risk of bone fractures Reduced muscle strength and increased risk of falling Increased blood markers of inflammation Increased risk of autoimmune disease, such as inflammatory bowel disease Increased susceptibility to infection Increased risk of dental cavities Increased risk of cancer Increased oxidative stress and related diseases such as diabetes and cardiovascular disease Increased risk of brain diseases such as dementia and depression Low circulating levels of vitamin D have also been associated with an increased risk of death from all causes, called “all-cause mortality”, as well as deaths from cardiovascular disease and can What are the health risks of vitamin k deficiencies? Although rare, vitamin K deficiency is associated with several notable health risks, including: Increased risk of osteoporosis Increased risk of bleeding disorders Increased risk of diseases with an inflammatory component, such as diabetes Increased risk of cardiovascular disease Low circulating levels of vitamin K have also been associated with a 19% increased risk of all-cause mortality. How could taking a vitamin D & K supplement help me? Vitamin D Multiple scientific studies show benefits from taking supplements of vitamin D. These include: Reduced incidence of viral infections Reduced incidence of dental cavities Reduced incidence of cancer (when administered daily) Reduced symptoms of Polycystic Ovary Syndrome (PCOS) Increased bone mineral density (when supplemented with calcium) Reduced risk of falling (especially when combined with calcium) Reduced depressive symptoms Reduced mortality in critically ill patients Improved blood markers in patients with ulcerative colitis Reduced insulin resistance in non-diabetic pregnant women Reduced C-reactive protein, a biomarker of inflammation Reduced systolic blood pressure Reduced exercise-induced muscle cell damage Improved non-verbal memory in healthy adults Improved glycemic control in diabetics Vitamin K For vitamin K, scientific studies also show benefits of supplementation, including: Decreased risk of bone fractures Improved bone mineralization and strength Reduced risk of developing diabetes Improved glycemic control Reduced C-reactive protein, a biomarker of inflammation Reduced wound healing time (when applied topically) Reduced symptoms of peripheral neuropathy (in patients with vitamin B12 deficiency or Type II Diabetes) Improved markers of cardiovascular disease Importantly, supplementation with vitamin K2 and vitamin D in combination has shown positive effects on bone mineral density when compared to a control group eating a regular diet. Should I take a calcium supplement when taking vitamin D & K? One of the main effects of vitamin D is to increase calcium absorption from the intestine, which – along with vitamin K – will allow calcium to be deposited into bone. But for this to occur, dietary or supplementary calcium must be ingested as well, or else there won’t be any calcium present to absorb! + More Some research has shown that bone mineral density improves when taking vitamin D supplements, provided it is taken along with calcium. Research has also shown that supplementation with vitamin D and calcium reduces the risk of total fractures by 15%, and the risk of hip fractures by 30%. However, not all studies have shown these benefits, leading some researchers to conclude that taking calcium (with vitamin D) for the prevention of osteoporosis and fractures is unwarranted. Some research has also suggested that taking supplemental calcium can have adverse effects on the cardiovascular system. This has led to a debate over whether taking calcium supplements to prevent osteoporosis has more benefits than risks. There’s no doubt, however, that calcium is an essential mineral. Ideally, it should be obtained from foods, such as dairy foods, almonds, and sardines. A little-known fact is that natural water also often contains calcium, which is removed with many modern filtration systems. Drinking calcium-rich mineral water in place of filtered water can be source of dietary calcium intake. Interestingly, the daily target range of calcium intake from diet and/or supplements varies widely among health organizations, from a minimum of 400mg to up to 1300mg per day, depending on age and gender. These recommendations have also changed across time, which shows a lack of clarity regarding optimal intake. If you consume very little calcium in your diet, then taking a supplement may be warranted. Many supplements on the market are quite high in calcium, with 500-1000mg per serving. These should be avoided. It’s better to take a supplement that more closely mimics dietary intake, at 250mg or less. If your calcium intake is extremely low, a low dose supplement could be taken 2 to 3 times per day. Are there nutrients other than calcium and vitamin K that interact with vitamin D? Yes! Magnesium is another nutrient that is interacts with vitamin D. Many enzymes that synthesize and metabolize vitamin D are dependent on magnesium for proper functioning, so optimal magnesium status is important for vitamin D. Most people do not consume sufficient dietary magnesium, and due to depletion of magnesium from our soil and foods, supplementation may be necessary to meet our daily needs. Vitamin A is another nutrient that interacts with vitamin D. Some vitamin D binds to vitamin A, forming a unit called a “heterodimer”. This A/D heterodimer can regulate the expression of many different genes, including several involved in bone health. Vitamin A is found in foods like liver, fish, eggs, and dairy, while pre-vitamin A (also known as carotenoids) are found in plant foods like leafy greens, peppers, and carrots. Ensuring adequate intake of vitamin A is important when supplementing with vitamin D. Vitamin A can be consumed through foods and supplements, and it is also added to some foods (like breakfast cereals) via fortification. Survey data has shown that 22% of the US population suffers from vitamin A deficiency, while 33% consume an excess. Since there are serious risks (like birth defects) associated with taking too much vitamin A, widespread supplementation is not recommended, although it is certainly warranted in some cases. shop fringe vitamin D & K What should I look for in a vitamin D & K supplement? (1) Read the ingredients – Most dietary supplement will contain both active and inactive or “other” ingredients. You need to pay attention to both. The active ingredients are the ones that you are looking for, and a vitamin D and K supplement will contain at least one form of each as an active ingredient. Choose the form that best meets your needs (see #3 in this list for more details!). Although this information may be hard to find, it’s helpful to know where these active ingredients are sourced from. Naturally sourced ingredients are always better than artificial ones. + More The inactive ingredients are usually there to: (1) provide bulk (filler), (2) hold the product together (binding agents, coatings), (3) add flavor or sweetness, or (4) keep the product from clumping together (flow enhancers). Sometimes this list is long, and it’s often where some undesirable ingredients sneak in, such as potassium sorbate, artificial colors, or titanium dioxide. It’s best to keep this list short and naturally sourced. (2) Verify product purity – Only choose high quality products that verify their purity via an unbiased chemical analysis performed by a third-party lab. These analyses should be reported in a Certificate of Analysis (COA) that is readily available to consumers, often through a QR code link. COA’s should be available for each batch of products, and will measure contaminants such as heavy metals, microbes, and pesticides. (3) Consider the form(s) of vitamin D & K in the supplement – There are two forms of vitamin D that are found in dietary supplements, vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is sourced mainly from animals, although lichen is a vegan source of D3. Vitamin D3 is the form made in humans following exposure to UVB light. In contrast, vitamin D2 is sourced from plants. Vitamin D3 is largely recognized as being more “bioavailable”, meaning more of the vitamin that is ingested gets delivered to body tissues. Studies that directly compare the bioavailability of D3 to D2 show that vitamin D3 raises blood levels of 25-hydroxyvitamin D more than vitamin D2, so it is preferable to choose a supplement containing vitamin D3. If you are vegan, choose a supplement that contains D3 sourced from lichen. As previously described, there are also two forms of vitamin K, vitamin K1 (phylloquinone) and vitamin K2 (menaquinones). Vitamin K1 comes mainly from plants, while vitamin K2 is made by bacteria and is found in animal-based and fermented food. Vitamin K2 is further subdivided into MK-4 through MK-13. Each of these subgroups of vitamin K2 has a slightly different molecular structure. Dietary supplements usually include MK-4 or MK-7. MK-4 occurs naturally in foods including liver, butter, and cheese, while MK-7 is made through fermentation, with the best source being Japanese fermented soybeans (called Nattō). Studies have shown that vitamin MK-7 is more bioavailable than vitamin MK-4, so it is preferable to choose a supplement containing vitamin MK-7. (4) Choose the supplement form you prefer – Supplements come in three main forms: capsules/tablets, powders, or liquids. Which one you choose is really a personal preference. Powders and liquid can be added to liquids, like smoothies, and are a great option if you don’t like swallowing pills. How is Fringe Essentials Vitamin D & K different from other supplements? Fringe Essentials Vitamin D & K has three highly unique attributes that make it superior to other products on the market: + Water Solubility Water Solubility – We’ve already covered that both vitamin D and K are fat-soluble vitamins. The absorption of fat-soluble vitamins is complex, which results in a lower bioavailability than water-soluble vitamins (recall that bioavailability refers to how much of the ingested nutrient is delivered to body tissues). The bioavailability of fat-soluble vitamins can be increased significantly through a safe and simple conversion process that makes them water-soluble and able to readily be absorbed through the walls of the small intestine. Research has demonstrated that water-soluble vitamin D is about twice as bioavailable as fat-soluble vitamin D. Another advantage to making vitamin D and K water-soluble is that it will eliminate the competition that occurs for the absorption of fat-soluble vitamins. And when you supplement with water-soluble vitamin D and K, you don’t need to consume them with food (especially food that contains some fat) to optimize absorption, like you do with fat-soluble vitamins.As a water-soluble powder, Fringe Essentials Vitamin D & K can be added to any liquid where it will dissolve easily without residue. + Vegan D3 Vegan D3 – Research has clearly demonstrated that vitamin D3 is superior to vitamin D2 at raising blood levels of 25-hydroxyvitamin D. The vast majority of vitamin D3 supplements source the vitamin from sheep’s wool, which produces a waxy substance called lanolin. Lanolin is extracted from sheep’s wool and put through a process which creates and extracts vitamin D3 using UVB light and chemical solvents. Because it is animal based, lanolin-derived vitamin D3 is not suitable for vegans. Fringe Essentials Vitamin D & K uses the only vegan source of vitamin D3, which is lichen. Lichens are living organisms that consist of fungus combined with algae or cyanobacteria. Lichen also make vitamin D3 following exposure to UVB. Lichen-derived vitamin D3 is identical to that produced from sheep’s wool, but is non-animal based, making it suitable for everyone. + Vitamin MK-7 Vitamin MK-7 – Fringe Essentials Vitamin D & K contains vitamin MK-7, the most bioavailable form of vitamin K. It is derived from the fermentation of Nattō, which is plant-based and suitable for vegan diets. The other ingredients in Fringe Essentials Vitamin D & K water-soluble powder are all natural and non-GMO. They include inulin and myo-inositol (also sometimes called vitamin B8) to help with dosing, medium chain triglyceride (MCT) oil to help with emulsification, and licorice extract for increased bioavailability. Dosing & Safety Fringe Essentials Vitamin D & K contains 2500IU of vitamin D3 and 130mcg of vitamin K2 (as MK-7). Because our vitamins are water soluble, they are more readily absorbed than most vitamin D and K supplements on the market, which means you don’t need to take as much to have the same effect. + Learn more For adults, we recommend using 1 scoop of Fringe Essentials Vitamin D & K per day as a maintenance dose when sun exposure is limited. A maintenance dose is meant to maintain blood levels of 25-hydroxyvitamin D within the range of 40-60ng/mL. However, if your blood vitamin D is very low, it may be necessary to take more until you reach this target range. The only way to know for certain how your body is responding to supplementation is to have your blood tested. This inexpensive test can be ordered by your health care provider, and home testing kits are also available. Lesser amounts can be taken when direct sun exposure is higher because skin synthesis of vitamin D will be much higher. Kids can also take Fringe Essentials Vitamin D & K. Based on age, the recommended doses are: for children aged 1-3 years old, ¼ scoop per day; ages 4-8, ½ scoop per day; ages 9-13, ¾ scoop per day; ages 14+, 1 full scoop per day. As with adults, the only way to know for certain how a child is responding to supplementation is to have their blood tested. For children under 1 year of age, please consult a health care provider before using. Vitamin D and K are safe to take when pregnant and breastfeeding. Of course, consult your doctor before beginning a supplement regimen. Fringe Essentials Vitamin D & K is incredibly safe. We use high quality ingredients and test every batch of our final product to ensure safe levels of toxic ingredients, including heavy metals, molds, and pesticides. We also leave out all the stuff you don’t want like artificial sweeteners, additives, gums, and ‘natural flavors’. Is there anyone who should not take a vitamin D & K supplement? One group that needs to be cautious about vitamin K supplementation is people taking anticoagulant, or blood thinning, medications. Taking high levels of vitamin K when on anticoagulants can decrease the effectiveness of the drug, which could increase the risk of blood clot formation. This is because of vitamin K’s important role in the blood clotting cascade. To recap Vitamin D deficiency is rampant in modern society. Sunshine provides us with a free and natural source of this essential vitamin, but on average, we spend 90% of our time indoors, leaving this vital resource untapped. Since it’s difficult to consume enough vitamin D from the diet, adding a high-quality supplement to your daily health regimen is an easy fix. Fringe Essentials Vitamin D & K combines vitamin D with vitamin K, a duo that is needed for optimal bone and cardiovascular health. In contrast to most supplements on the market, ours is water-soluble, which means more of it gets to where it’s needed. It’s also naturally sourced, non-GMO, and vegan – containing only what you need, without unnecessary additives and fillers. Simply mix 1 scoop of Fringe Essentials Vitamin D & K into your water, smoothie, coffee, tea, or favorite beverage daily. You can also take a bit more or less, depending on the season and your unique needs! The contents in this blog; such as text, content, graphics are intended for educational purposes only.

Red Light Therapy vs Ice
Red Light Therapy vs Ice. If you were to take a sample of doctors and athletic trainers and ask them what therapy they recommend that people use for post-exercise muscle recovery, you are guaranteed to find that a majority will tell you to apply ice. Cryotherapy or icing has long been considered the gold standard for dealing with pretty much any kind of inflammatory process, including the muscle inflammation that occurs following strenuous exercise. Cryotherapy is a therapeutic technique that involves exposing the body or specific areas to extremely cold temperatures, typically using ice packs, cold water immersion, or specialized cryochambers. But research has now clearly shown that when you put icing head-to-head with Red Light Therapy – which uses red and/or near infrared light to influence biology - and look at which one works better to support exercise recovery, Red Light Therapy consistently comes out on top. In 2019, a scientific article was published that reviewed three clinical trials and two animal studies comparing cryotherapy to Red Light Therapy. Each human clinical trial administered both red and near infrared light, while the two animal studies used near infrared light only, and light or cryotherapy were applied following exercise. The outcome for each study was post-exercise muscle recovery. All five studies found that Red Light Therapy was superior to cryotherapy at improving outcomes related to exercise recovery. This included decreased delayed onset muscle soreness and reduced muscle inflammation. The research also showed that in contrast to Red Light Therapy, cryotherapy did nothing to prevent muscle damage from occurring following strenuous exercise, since markers of muscle damage like creatine kinase were only reduced with Red Light Therapy. The superiority of Red Light Therapy over cryotherapy makes perfect sense when you consider the mechanisms of how the two modalities work. In a nutshell, red light therapy stimulates mitochondria to produce energy and modulate oxidative stress, decreasing cellular markers of inflammation. Red Light Therapy also induces cellular changes like increasing the production of growth factors. This is how it can have effects such as decreasing inflammation and healing damaged muscle fibers, and how it can positively influence many aspects of exercise recovery. In contrast, cryotherapy constricts blood vessels and decreases blood flow, which leads to less edema formation (swelling). This might reduce inflammation and decrease pain, but it really does nothing on a cellular level to support healing. In fact, it’s been argued by some experts to do the opposite. Several criticisms of cryotherapy have been raised, including that it only provides temporary relief and does not promote long-term healing. The studies described in this analysis used light that was quite low in intensity. Light intensity refers to the amount of light being delivered by a device. It is also sometimes called irradiance, and it’s usually measured in units called mW/cm2. Red Light Therapy devices on the market vary widely in terms of their intensity. While it’s common to see marketing claims that high intensity products (at upwards of 100mw/cm2) are needed to reap the benefits of Red Light Therapy, this research (and a lot of other studies too), show that this is false. When it comes to using Red Light Therapy for post-exercise muscle recovery, research has clearly shown that more is not better. Instead of high intensity products, it’s best to use a device that delivers both red and near infrared light at a low to moderate intensity. Fringe Red Light Therapy products are great options for post-exercise support, delivering the optimal intensity of light at between 20 and 40mw/cm2. This is like the intensity of the sun. Fringe Red Light Therapy wraps even have the advantage of being portable and cordless, offering the flexibility of immediate use, including on the sideline! So, the next time you have a hard workout, reach for a Red Light Therapy device instead of ice to support muscle healing. And the advantages of Red Light Therapy over cryotherapy extend to healing for other conditions as well. Basically, you can use Red Light Therapy for anything that you would consider using ice for. By using Red Light Therapy instead, you’ll not only decrease pain and inflammation, but you’ll also activate cellular healing mechanisms that will help you to feel better faster.

Light Therapy and Vibration for Female Pelvic Health
One of our missions at Fringe is to create high quality, evidence-based light therapy products, and to make them readily accessible to consumers. Our goal is to help people heal from the conditions that commonly ail them – like arthritis, post-exercise muscle soreness, and eczema (just to name a few) - in the comfort of their own homes. Recently, we turned our attention to some of the more common conditions affecting women and those born female at birth specifically: disorders of the female pelvis. Disorders related to female pelvic health (including pelvic floor pain and dysfunction, urinary incontinence, sexual dysfunction, and vaginal infections) are incredibly common, affecting up to 50% of the population at some point in their lives. shop fringe pelvic wand Enter, the fringe pelvic wand In response, we made the Fringe Pelvic Wand - which combines light therapy with vibration, two well-established healing modalities - which may support recovery from these challenging issues. What is red light? Light therapy (also known as photobiomodulation) is the application of light with specific wavelengths to the body for the purposes of influencing biology. The most common form of light therapy uses red light, which is visible as the color red, and/or near infrared light, which is not visible but can be felt as heat. Blue light is also used in many light therapy products, mainly for its antimicrobial effects. Red, near infrared, and blue light are naturally produced by the sun, which gives off solar radiation. The term radiation describes energy that is transmitted in the form of waves or particles. The spectrum of light in our environment consists of both light we can see (visible light) and light that our eyes can’t perceive (invisible light). This is called the electromagnetic spectrum. The visible light spectrum is quite narrow, consisting of wavelengths that range from 400 to 700nm and span from violet to red in color. Blue and red light are part of this visible light spectrum, while near infrared light is not. Different colors of light have different depths of skin penetration, with red and near infrared light penetrating the deepest. While early research on light therapy used primarily lasers, more recent research has found that LED’s can also be used, which also have the advantage of applying light to a larger area of the body as well as an improved safety profile. The use of LED in red/near infrared/blue light therapy devices has also greatly reduced the cost of treatment, making it something that can be done in the comfort of one’s own home. Both laser and LED lights have been used in research and practice to support pelvic health. Light therapy delivers light at a measurable level of intensity, which can be generally classified as low, moderate, and high. The intensity of sunlight is between 20 and 40mW/cm2, which is described as the “sweet spot” between higher intensities, which can have harmful effects, and lower intensities, which will have no effect at all. This range is optimal for healing while minimizing adverse effects, and is the range used in the Fringe Pelvic Wand. How might light therapy support female pelvic health? Light therapy may have physiological effects related to female pelvic health, including: Tissue Rejuvenation Loss of connective tissue, such as collagen and elastin, in the female pelvis is commonly experienced by women as they age and can also occur because of childbirth and infections. Through its effects on mitochondria, light therapy (especially red and near infrared light) may increase cellular energy production and increase connective tissue production. Light therapy may also modulate the production of reactive oxygen species, causing a shift towards tissue rejuvenation rather than breakdown, and may support muscle strengthening. Reduced Inflammation & Pain Chronic pain is commonly associated with disorders of the pelvic floor, which may also be associated with pelvic inflammation. Light therapy (especially with red and near infrared light) may have powerful effects on inflammation. Studies have found that light therapy may affect levels of many molecules involved in inflammation, including reactive oxygen species, reactive nitrogen species, and prostaglandins. Increased Blood Flow A decrease in blood flow to tissues in the female pelvis, especially the vagina, occur with age. This loss of blood flow negatively affects tissues by reducing the supply of oxygen and nutrients and contributes to age associated changes such as vaginal atrophy. Light therapy (especially red and near infrared light) may increase blood flow in two ways. First, it may increase levels of nitric oxide through its effects on the mitochondria, which causes vasodilation. The dilation of blood vessels allows more blood to flow through. Second, it may increase angiogenesis, which is the synthesis of new blood vessels. A greater density of blood vessels may increase the delivery of blood to tissues. Effects on Microorganisms Infections with pathogenic microorganisms in the female pelvis are quite common, and include bacteria (such as chlamydia), fungi (such as candida), and viruses (such as HPV). The vagina also naturally hosts the vaginal microbiome, which has a balance of microorganisms. When imbalanced, susceptibility to infections and bacterial vaginosis is increased. Light may have effects on microorganisms, both pathogenic and non-pathogenic. Blue light may have powerful effects on pathogenic microbes that can infect the vagina, such as candida, while red light may have positive effects on the microbes that comprise the microbiome, including the vaginal microbiome. Some clinical conditions related to female pelvic health that may improve with light therapy include: Vaginal candidiasis Human papillomavirus and associated vaginitis and cervicitis Vulvovaginitis Chronic pelvic pain Urinary incontinence and sexual dysfunction Overactive bladder Interstitial cystitis/bladder pain syndrome Menopause Episiotomy recovery What is vibration therapy? Vibration therapy may have physiological effects related to female pelvic health, including: Tissue Rejuvenation Vibration therapy may have many effects on cells associated with the structural integrity of the female pelvic. Collagen in particular may respond to vibration therapy, especially at low magnitudes, and both collagen and muscle formation respond well to low magnitude vibration at between 8 and 10Hz. Increased Blood Flow Vibration therapy may increase blood flow, after as little as 10 minutes of therapy. Increasing blood flow helps to perfuse tissues with oxygen and nutrients and improve function and speed healing. Muscle Tone Regulation While proper functioning of the pelvic floor muscles is integral to bowel, bladder, and sexual health, in many women these muscles are weak. Others experience chronic hypertonicity in muscles of the pelvic floor, which is also suboptimal. Vibration therapy may regulate muscle tone in two ways. First, it may decrease spasticity in muscles that are overactive. Second, it may improve the potential to voluntarily contract muscles, such as those of the pelvic floor, which are poorly controlled in between 30 and 50% of women, and in this way activate and strengthen the muscle. Muscle tone regulation is accomplished by activating muscles via a spinal reflex and increasing blood flow. Decreased Pain Vibration therapy may reduce many different pain types, including neuropathic pain, low back pain, and muscle pain. This may happen via several mechanisms, such as regulating muscle tone and increasing blood flow. Some clinical conditions related to female pelvic health that may improve with vibration therapy include Urinary incontinence Pelvic floor dysfunction Vulvodynia (a pelvic pain condition) Pelvic pain penetration disorder Sexual dysfunction The Fringe Pelvic Wand The Fringe Pelvic Wand delivers three wavelengths of light via three modes: + Mode 1 - Deep Rejuvenation MODE ONE - red/near infrared light (630nm & 830nm): delivers both red (630nm) and near infrared (830nm) light to the pelvic tissues. This mode may help with pelvic pain and inflammation; bladder and muscle health; optimizing the vaginal microbiome; increasing the production of collagen and elastin; and improving blood flow and tissue health. Use Mode 1 for deep pelvic rejuvenation if you are NOT sensitive to light or heat. + Mode 2 - Antimicrobial MODE TWO - Blue Light (415 nm): delivers blue light (465nm) to the pelvic tissues. This mode may support the destruction of microbes including fungus and bacteria and healing from yeast infections and bacterial vaginosis. + Mode 3 - Rejuvenation MODE THREE - Red Light (630 nm): delivers only red (630nm) light to the pelvic tissues. This mode may help with pelvic pain and inflammation; bladder and muscle health; optimizing the vaginal microbiome; increasing the production of collagen and elastin; and improving blood flow and tissue health. Use Mode 3 for pelvic rejuvenation if you ARE sensitive to light or heat. The Fringe Pelvic Wand also delivers optional vibration, via four modes: + Mode 1 - 10hz (default mode) MODE ONE: provides very low frequency vibration which may help to support muscle relaxation and pain reduction. + Mode 2 - 50hz MODE TWO: provides low/moderate frequency vibration which may help to support muscle relaxation, reduce pain, and increase awareness of pelvic muscle function. Mode 2 can be combined with gentle pelvic floor exercises. + Mode 3 - 90hz MODE THREE: Provides moderate/high frequency vibration that increases awareness of pelvic muscle function and may help to support pelvic muscle contraction. Mode 3 can be combined with moderately active pelvic floor exercises. + Mode 4 - 120hz MODE FOUR: provides high frequency vibration that may help to support strengthening of pelvic muscles. Mode 4 can be combined with active pelvic floor exercises. Let's get started How to use the fringe pelvic wand Light & Vibration Therapy Safety The safety of light and vibration therapy has been demonstrated in thousands of research studies. However, there are some precautions to be aware of before you begin your therapeutic journey.Photosensitivity is the main contraindication to light therapy. If you are sensitive to light or are using medications that increase light sensitivity (see https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7672668/ for a recent list), you may need to reduce treatment time, interval, and/or frequency, as well as reduce light intensity. Light & Vibration Therapy Safety Here are some other precautions to consider. Please don’t: Exceed the recommended treatment times and frequency. Use on open fresh wounds. Use in combination with lotions, balms or other topical products that contain heat producing ingredients. Use with a non-water based lubricant. If you’re pregnant, we recommend checking with your health care provider to see if they think it’s appropriate for you to use the Fringe Pelvic Health Wand. They can assess your unique health needs and determine if light and vibration therapy is right for you. However, we do know that it’s a great tool to use postpartum when it may help to support healing and recovery of pelvic tissues. Co-Author Elizabeth Frey, FCAMPT, MCISC (MANIP), MSc.

Should I Take a Magnesium Supplement?
Should I take a magnesium supplement? The simple answer to this question is: Most likely, yes. Scientific evidence suggests that many people are at risk of magnesium deficiency, even those consuming a healthy diet. There are many reasons for this, most of which are out of our control. Given the critical importance of magnesium in the human body, and the significant health risks that accompany even a subclinical magnesium deficiency, regular supplementation with a high-quality dietary supplement is a wise investment in your health. shop fringe magnesium What is Magnesium? Magnesium is one of the most abundant minerals, both in the earth and inside the human body. Most magnesium in the body is found inside cells, rather than in the blood, and it is especially concentrated in the muscles and bones. In the body, magnesium carries a positive charge, and is therefore referred to as an ion or electrolyte. The recommended intakes of magnesium have been determined and are based on age and gender. These values are known as the dietary reference intakes (DRI’s). Recently, it has been suggested that the DRI’s for magnesium are too low because they haven’t been adjusted for rising body weights. The new estimates recommend an additional intake for adults of between 60-235mg magnesium per day beyond what is shown in table 1. What does magnesium do in the body? Magnesium is involved in virtually every cellular metabolic and biochemical process in the human body. As a cofactor or activator for over 800 chemical reactions, magnesium regulates everything from metabolism to protein synthesis, to DNA repair and synthesis. It is also involved in conveying messages between molecules within the cell as well as in regulating cell replication. What are good sources of magnesium? Magnesium is found in many foods, both plant and animals. Some good sources of magnesium are: Green leafy vegetables Legumes Nuts Seeds Whole grains Good sources of magnesium should contain around 40-80mg per serving. Meat, dairy and fruit also contain some magnesium but at lower amounts. A general rule of thumb is that the more highly processed a food, the less magnesium it will contain (unless it has been fortified). Although there are many food sources of magnesium, a drastic loss of magnesium from agricultural soil over the last century has led to a decrease in the magnesium content of plant foods due to their inability to absorb sufficient magnesium from the earth. For example, the magnesium content of vegetables has decreased by 80-90% over the last century. As a result, supplementation with magnesium may be necessary to avoid deficiency. What is the prevalence of Magnesium deficiency? There are two types of nutrient deficiencies, frank and subclinical. Frank deficiencies have obvious signs, while subclinical deficiencies do not. Frank deficiencies of magnesium are rare because the kidneys can limit its excretion. But subclinical deficiencies are extremely common, since over half of the US population don’t consume the recommended amount. In fact, according to a research article in the Open Heart medical journal, “the evidence in the literature suggests that subclinical magnesium deficiency is rampant and one of the leading causes of chronic diseases including cardiovascular disease and early mortality and should be considered a public health crisis.” What are the causes of Magnesium deficiency? As already described, two of the main causes of magnesium deficiency are (1) low intake of dietary magnesium, and (2) a substantial loss of magnesium from agricultural soil causing a decrease in the magnesium content of foods. These two issues will be compounded, such that even when people attempt to consume sufficient dietary magnesium, they may be unable to. There are also several other factors that increase the risk of magnesium deficiency. These include: Magnesium also interacts with other nutrients, which can increase the risk of deficiency. For example, taking high doses of vitamin D can increase the loss of magnesium from the body, while taking high doses of zinc can interfere with magnesium absorption. High doses of fiber can also interfere with magnesium absorption. What are the health risks of Magnesium deficiency? Because of its nearly ubiquitous role in the body’s processes, low levels of magnesium can create widespread physiological dysfunction. And because of the widespread incidence of low magnesium intake, magnesium deficiency is recognized as an important global concern. A frank magnesium deficiency will manifest with clinical signs, including: Low appetite Nausea and vomiting Fatigue and weakness Muscle spams or tremors Abnormal heart rhythm Convulsions Psychiatric disturbances But because the kidneys regulate the excretion of magnesium from the body, it’s rare to have magnesium be depleted to the point where these potentially life-threatening symptoms occur. Far more common is subclinical magnesium deficiency, which often does not have obvious signs. Because it’s so easy to under consume magnesium, and since the signs of subclinical magnesium deficiency are hard to spot, it often extends over time leading to long-term adverse complications. These include a wide range of health problems and chronic diseases, including: Cardiovascular diseases Diabetes Migraines Osteoporosis Asthma Metabolic disorder Alzheimer’s Disease Parkinson’s Disease Premenstrual Syndrome Dysmenorrhea These conditions have potentially devastating consequences, which makes magnesium a critical nutrient of concern for public health. How could taking a magnesium supplement help me? There are both long-term and short-term benefits to ensuring adequate magnesium intake, which for many people, will require taking a magnesium supplement. As just described, there is a long list of health problems and chronic diseases associated with a long-term subclinical magnesium deficiency, many of which can be helped by taking a magnesium supplement. Can I take too much magnesium? Magnesium toxicity is mostly seen with consumption of high doses of magnesium containing laxatives and antacids. Consumption of more than 5000mg per day can cause toxicity, with symptoms including low blood pressure, nausea, vomiting, muscle weakness, and even cardiac arrest. It would be nearly impossible to consume this much magnesium through dietary supplements, which usually contain less than 300mg per serving, and totally impossible through food. Because the excretion of magnesium is regulated by the kidneys, it is difficult to take too much, and is not a concern except with consumption of magnesium containing medications. How do I choose a Magnesium supplement? Read the ingredients - Most dietary supplement will contain both active and inactive or “other” ingredients. You need to pay attention to both. The active ingredients are the ones that you are looking for; for example, a magnesium supplement will contain at least one form of magnesium as the active ingredient. Some supplements, like multi-vitamins, have many active ingredients. Usually, these are vitamins, minerals, of phytochemicals derived from plants. Although this information may be hard to find, it’s helpful to know where these active ingredients are sourced from. Naturally sourced ingredients are always better than artificial ones. The inactive ingredients are usually there to: (1) provide bulk (filler), (2) hold the product together (binding agents, coatings), (3) add flavor or sweetness, or (4) keep the product from clumping together (flow enhancers). Sometimes this list is long, and it’s often where some undesirable ingredients sneak in, such as potassium sorbate, artificial colors, or titanium dioxide. It’s best to keep this list short and naturally sourced. Verify product purity – Only choose high quality products that verify their purity via an unbiased chemical analysis performed by a third-party lab. These analyses should be reported in a Certificate of Analysis (COA) that is readily available to consumers, often through a QR code link. COA’s should be available for each batch of products, and will measure contaminants such as heavy metals, microbes, and pesticides. Consider the form(s) of magnesium in the supplement – There are several different forms of magnesium that are included in dietary supplements, each of which has unique properties. Look for ones that are bioavailable and easy on digestion. The forms of magnesium that are most likely to cause diarrhea are magnesium chloride, carbonate, oxide, and gluconate. Magnesium malate shows high bioavailability compared to the commonly supplemented forms of magnesium oxide and magnesium citrate. Other organic forms of magnesium such as magnesium glycinate and magnesium orotate also show high bioavailability. Some forms of magnesium have also shown unique health benefits; for example, magnesium orotate helps with cardiovascular and gut health. While all magnesium supplements can help to prevent magnesium deficiency, some forms may be better suited to your unique needs. Choose the supplement form you prefer – Supplements come in three main forms: capsules/tablets, powders, or liquids. Which one you choose is really a personal preference. Powders and liquid can be added to liquids, like smoothies, and are a great option if you don’t like swallowing pills. Fringe Essentials Magnesium Powder The Fringe Essentials Magnesium Powder contains three forms of magnesium: orotate, malate, and glycinate, at 173mg total and 41% of the recommended Daily Value. These forms of magnesium have been shown to be better absorbed into the body, and they’re easily digested. Each one has unique health benefits that make them well suited to not only ensure sufficient magnesium intake, but also to reap a wide range of health benefits. Here’s what they do: + magnesium glycinate: Magnesium glycinate is a standout in helping to reduce anxiety, promote relaxation, support deep sleep, reduce muscle tension, and balance mood. _____________________________________ + magnesium orotate: Magnesium orotate is one of the best forms of magnesium to consume for heart health. It’s been shown to help with hypertension and heart disease, and to reduce risks of heart attacks. It also supports gut and mental health and helps with exercise recovery. It may even be helpful in diabetes and Alzheimer’s Disease. _____________________________________ + magnesium malate: Magnesium malate is great for chronic pain, inflammation, energy production, and muscle tension and recovery. _____________________________________ The other ingredients in Fringe magnesium powder are all natural, and include non-GMO inulin to help with dosing, organic monkfruit extract for a bit of natural sweetness, and vitamin C for an antioxidant boost. Simply mix 1 scoop of magnesium into your water, smoothie, or favorite beverage 1-2 times per day. shop fringe magnesium

Should I Take an Electrolyte Supplement?
The simple answer to this question is: Most likely, yes. The story of fluid-based electrolytes is very much a story of water – which as you will see, has changed dramatically in the last few decades. As water processing has evolved to remove harmful contaminants, essential nutrients (in the form of minerals) have also been lost, with potentially negative consequences. In this article, you’ll learn about the role of fluid-based mineral electrolytes in supporting human health, and how this has changed across time. shop fringe electrolytes How has the composition of drinking water changed across time? When most people think of water, they think of the water molecule: H2O. What many people don’t realize is that water in nature also contains a wide range of nutrients in the form of dissolved minerals. As it travels over rocks and through the earth, minerals make their way into water. The result is complex fluid matrix that is far more than just H2O. The nutrients (minerals) commonly found in natural water include: Sodium Potassium Magnesium Calcium Trace minerals, such as selenium, iodine, molybdenum, zinc, copper, manganese, and chromium. Unfortunately, the water that is accessible to most humans on earth also contains a wide range of potentially harmful contaminants. While developing countries experience the greatest contamination, water in developed countries also often contains contaminants of concern. For example, tap water in the US often contains things like lead, arsenic, and industrial and agricultural contaminants. Removing these contaminants is critical to supporting human health. To remove these undesirable compounds, water filtration devices are used. These devices pass water through a semi-permeable filtration membrane, and range in complexity from simple pitchers and countertop basins to industrial reverse osmosis filtration systems. Reverse osmosis filtration is also widely used in government, commercial, and military applications. Filtration devices do not distinguish between minerals such as magnesium, which are essential for human health, and harmful contaminants such as lead. The filters are non-specific and remove any molecules bigger than the size of the filtration pores, which include naturally occurring minerals. As a result of this processing, our modern filtered water becomes simple H2O. Should water be a source of essential nutrients? A little-known fact is that consumption of water from nature will make a small (but appreciable) contribution to our required nutrient intake, specifically the intake of some minerals, which are a class of micronutrient. Most commonly, recommended nutrient intake is defined using the Recommended Dietary Allowance (RDA), which refers to nutrients that come from food. But this term is a bit of a misnomer, as it ignores nutrient intake from water. Instead, the World Health Organization recommends that we use the term Recommended Nutrient Intake (RNI, also referred to as the Reference Nutrient Intake), which refers to nutrients that come from food and water. As already mentioned, there are many nutrients that occur naturally in water, including calcium, magnesium, sodium, chloride and potassium. These minerals are estimated to contribute between 1 and 20% of our recommended daily intake values when natural water is consumed. Water makes the most appreciable contribution to nutrient intake for calcium and magnesium, at up to 20%, while for most other minerals it provides between 1 and 5%. By removing minerals from water using processes such as reverse osmosis, we are eliminating a vital nutrient source. Putting minerals back into water, which can be done with electrolyte mineral formulations, is an easy way to circumvent this problem. Are there any health impacts of drinking highly filtered water? While it’s obviously important to remove harmful contaminants from water, this can’t be done without also removing essential nutrients. And there is clearly a downside to this removal. Here are a few important health risks that have been associated with drinking highly filtered water: Mineral loss from the body: Studies have shown that consumption of demineralized water can lead to a loss of body minerals that are excreted in the urine, faces and sweat. In kids, this can slow growth and lead to cavities. Water loss from the body: In addition to mineral losses, drinking demineralized water also leads to the loss of water from the body - there is an up to 20% increased excretion of body water in studies of human volunteers drinking demineralized water. Impaired electrolyte homeostasis: Drinking demineralized water may impair electrolyte homeostasis and lead to changes that may increase the risk of cancer. There is also some evidence of mineral intake specifically from water preventing disease in humans. For example, magnesium in drinking water is associated with protection against death from acute myocardial infarction (heart attack) among males. Similarly, drinking hard water (which contains dissolved electrolytes, including calcium and magnesium) is associated with protection against cardiovascular disease. Drinking hard water has also been associated with a decreased risk of some types of cancer, including stomach and esophageal, as well as stroke. Calcium rich water has also been found to support bone health. What are electrolytes? You’ve probably already realized that the minerals found in natural water have something to do with electrolytes. In fact, many of these minerals are electrolytes. Electrolytes are minerals that carry an electric charge and can conduct electricity in the body when in a dissolved state. The most important electrolytes in the body are sodium, potassium, chloride, magnesium, calcium, phosphorous, and bicarbonate. These charged ions are found throughout the body, and their levels are carefully maintained in balance, or homeostasis. What do electrolytes do in the body? The general role of electrolytes is to regulate physiological function, but each one is unique. Here is an overview of the primary electrolytes and their specific roles in the body. Why can’t I just consume electrolytes from food and supplements? Electrolytes have two sources in nature, food and fluids (especially water). And in modern society, we’ve added a third: dietary supplements. Both food and dietary supplements are good sources of electrolytes and should comprise the majority of nutrient intake. However, water can provide between 1 to 20% of certain minerals, and it is abundantly clear that consumption of electrolytes from water yields unique benefits irrespective of food and supplement consumption, including protection against: Mineral losses from the body Water losses from the body Some types of cancer Stroke Cardiovascular disease Consumption of electrolyte containing water also supports the maintenance of electrolyte homeostasis in the body, which is essential for optimal physiological function. Water that contains electrolytes is obtained in one of two ways: by drinking natural mineral rich water, or by adding a mineral rich electrolyte supplement to a demineralized water source, such as reverse osmosis water. Can electrolytes become deficient or imbalanced? Electrolyte imbalances can occur when blood levels become too high, or too low. Each electrolyte can become imbalanced, with potentially serious (and even life threatening) consequences. Levels of electrolytes are tightly regulated in the body for this reason, which occurs mainly at the level of the kidneys. Electrolyte deficiencies occur when there is Inadequate dietary consumption of a nutrient. Both imbalances and deficiencies are possible. Do some people need more electrolytes? Yes, there are some people who need more electrolytes. Anyone who – for whatever reason – is losing fluid from the body at a higher-than-normal rate will need to intake more to restore electrolyte balance. And anyone consuming low levels of electrolytes from food and water will require more to prevent deficiency. This applies to the following conditions: People who are exercising and sweating (even more so if in hot and/or humid conditions). People eating a low sodium diet, such as keto, paleo, or other low carb diets. Note – if you are on a low sodium diet because of a medical condition, such as a kidney disease, be cautious about supplemental sodium intake. People who are fasting. People experiencing illnesses involving vomiting and diarrhea. People with certain medical conditions, such as Postural Orthostatic Tachycardia (POTS) Increasing intake of mineral rich water, either natural or supplemental, as well as consuming more electrolyte containing foods, can help people meet these increased needs. How do I choose a mineral electrolyte supplement? Read the ingredients – Most dietary supplement will contain both active and inactive or “other” ingredients. You need to pay attention to both. Electrolyte supplements should contain several electrolytes, such as sodium, magnesium, chloride, and potassium, as the active ingredients. Although this information may be hard to find, it’s helpful to know where the active ingredients are sourced from. Naturally sourced ingredients are always better than artificial ones. For example, in an electrolyte supplement, a natural source of sodium and chloride would be natural sea salt. Electrolyte supplements usually also contain inactive ingredients. The inactive ingredients are usually there to: (1) provide bulk (filler), (2) hold the product together (binding agents, coatings), (3) add flavor or sweetness, or (4) keep the product from clumping together (flow enhancers). Sometimes this list is long, and it’s often where some undesirable ingredients sneak in, such as potassium sorbate, artificial colors, or titanium dioxide. It’s best to keep this list short and naturally sourced. Verify product purity – Only choose high quality products that verify their purity via an unbiased chemical analysis performed by a third-party lab. These analyses should be reported in a Certificate of Analysis (COA) that is readily available to consumers, often through a QR code link. COA’s should be available for each batch of products, and will measure contaminants such as heavy metals, microbes, and pesticides. Look at the amounts listed in the Nutrition Facts – Electrolyte supplements are not meant to provide high levels of the daily value of nutrients, so when you look at a Nutrition Facts table, the %DV (Daily Value) for each nutrient should be twenty or less. Minerals from natural water will be between 1 and 20% DV, so this is a simple rule of thumb to follow. An additional consideration is that if an electrolyte supplement can be added to water, rather than being pre-packaged in plastic bottles, contamination of the water with microplastics can be reduced. What's NOT in fringe electrolytes? Let’s start off describing what we’ve (intentionally) left out of Fringe electrolytes. They contain no: What's in the tub? Sodium Chloride from Sea salt: Sea salt provides both sodium (at 8%DV) and chloride (at 20% DV). It also contains small amounts of other minerals like iron, iodine, manganese, zinc, and selenium. We opted for a high-quality natural sea salt, sourced from Australian sea water, rather than table salt, because of its natural origin and more diverse mineral profile. Calcium from Calcified Algae Calcium is essential for supporting bone and teeth health, but also important for muscle and nerve function. Potassium: Potassium (at 2% DV) is essential for regulating many processes in the body, including heart, muscle, nerve, and blood vessel function. Magnesium from magnesium malate: Magnesium malate (at 3% DV) is a highly absorbable form of magnesium that helps reduce pain and inflammation, improve mood, and supports heart, nerve, and muscle health – without causing unpleasant digestive symptoms. Trace minerals: We wanted to up the ante on our electrolytes and supplement trace minerals – essential micronutrients which are critical in many biological processes in the body! Our trace minerals are naturally sourced from the Great Salt Lake and include selenium, iodine, molybdenum, zinc, copper, manganese, and chromium. These are present in small amounts that are below 1% DV. *Our ratio of sodium to potassium is at around 3:2, which is the same ratio used by the sodium potassium pump. Non-GMO Inulin: This is a soluble fiber derived from chicory root. It helps to maintain accurate dosing with the product and is also a prebiotic resistant starch which has a positive effect on gut health! shop fringe electrolytes Recap We’ve covered a lot of ground in this article, but the key takeaway is that mineral rich electrolyte supplements will help to support hydration and electrolyte balance. Adding minerals to water at between one and 20% of the recommended daily nutrient intake will restore your water to the way that nature intended. An easy way to do this is by using Fringe electrolytes as a regular part of your wellness routine. Simply mix 1 scoop of electrolyte powder into your water, 1-2 times per day. For a bit of natural flavor, add a squeeze of citrus or a few drops of essential fruit oil. Add a boost of hydration in the morning to start your day right, rehydrate after a tough workout, throw in your kiddos water to keep them hydrated in a clean way…there’s no right or wrong way to do it!

Light Therapy for Brain Health
Light Therapy for Brain Disorders Our understanding of brain health as being fundamental to our overall well-being dates to the time of the ancient Greeks. “Mens sana in corpore sano”, which translates to “a healthy mind in a healthy body”, was a foundational part of the Hippocratic philosophy. Hippocrates introduced the first classification of mental disorders and believed that the brain was the organ responsible for mental illnesses. His classes of mental disorders included melancholia, mania, insanity, and others. While those terms are no longer in use today, many modern brain disorder, such as depression and dementia, are foundationally like those ancient classifications. Importantly, Hippocrates believed that “natural” treatments would cure diseases. One such therapy was the use of sunshine, known as “heliotherapy”. shop red light therapy head wrap Brain disorders In modern society, brain disorders are becoming increasingly prevalent. Also referred to as neurological disorders, these conditions are estimated to be the second leading cause of death, causing 9 million deaths globally each year. While these diseases yield a massive economic burden in terms of health care costs, they also have an enormous impact on our quality of life. The prevalence of brain disorders is expected to increase significantly over the next several decades as the population both ages and grows. Categories of brain disorders There are several different categories of brain disorders. These include: autoimmune diseases (such as multiple sclerosis – MS), epilepsy, psychiatric disorders (such as depression and anxiety), neurodegenerative diseases (such as Alzheimer’s and Parkinson’s disease), neurodevelopmental disorders (such as ADHD and autism), stroke, traumatic brain injuries (such as concussions and chronic traumatic encephalitis), and brain tumors. While these disorders are all unique, they share fundamental pathological characteristics. Most involve an increase in oxidative stress, which involves excessive production of reactive oxygen species. The brain is especially vulnerable to oxidative stress because it has a high metabolic rate, and oxidative stress can occur both in chronic diseases (such as Alzheimer’s) and acute conditions (such as concussions). Alterations in brain metabolism are also common, which can precede and co-occur with oxidative stress. Brain metabolism accounts for around 20% of total metabolism, even though it only contributes 2% of total body weight. This makes the brain vulnerable to damage from metabolic effects such as those that occur with aging, poor diet, and trauma. Neuroinflammation, which involves inflammation in the brain as a response to disease and injury, also occurs. Oxidative stress, impaired metabolism, and neuroinflammation overlap, involving many of the same molecules. Brain disorders are notoriously difficult to treat. Because the blood brain barrier restricts entry of foreign substances into the brain, drug transport into the brain is limited. We are also limited by our lack of understanding these diseases. Experts admit that we actually know very little about how the brain works, for a variety of reasons. Given this complexity, using non-pharmacological interventions to treat the foundational pathologies of brain diseases (including oxidative stress, impaired metabolism, and neuroinflammation) is a great starting point. Light therapy, or photobiomodulation, is one such approach. Light therapy Light therapy (also known as photobiomodulation) is the application of light with specific wavelengths to the body for the purposes of influencing biology. The most common form of light therapy uses red light (RL), which is visible as the color red, and/or near infrared light (NIRL), which is not visible but can be felt as heat. The RL used in light therapy usually ranges from 600 to 700 nanometres (nm), with the unit nm referring to distance the light wave travels in one cycle. The NIRL used in light therapy usually ranges from 800 to 900nm. RL and NIRL are naturally produced by the sun, which gives off solar radiation. The term radiation describes energy that is transmitted in the form of waves or particles. The spectrum of light in our environment consists of both light we can see (visible light) and light that our eyes can’t perceive (invisible light). This is called the electromagnetic spectrum. The visible light spectrum is quite narrow, consisting of wavelengths that range from 400 to 700nm and span from violet to red in color. RL is part of this visible light spectrum, while NIRL is not. Red and near infrared light therapy is the application of artificially generated light in the red and near infrared spectral bands. The term “red light therapy” usually describes the use of both RL and NIRL, although only the red light produced by the device is visible to the naked eye. IRL can still be perceived by the body as heat when it contacts skin. How Does Red Light Therapy Affect Brain Health? Light therapy, specifically the application of red and near infrared light, positively impacts all three foundational pathologies of brain disorders: oxidative stress, impaired metabolism, and neuroinflammation. Oxidative Stress: Light is absorbed in cells by molecules called chromophores, many of which are found inside the mitochondria. Mitochondria are involved in regulating the production the reactive oxygen species that cause oxidative stress when present in high amounts. Light therapy has been shown to modulate oxidative stress and reactive oxygen species production. Impaired Metabolism: Through its impact on mitochondria, light also affects metabolism. In addition to regulating reactive oxygen species production, mitochondria also make the energy currency of the cell, called ATP. Specifically, RL and NIRL stimulates cytochrome c oxidase, a mitochondrial enzyme that produces ATP. This increases ATP synthesis which provides more energy to brain cells. Neuroinflammation: Red and NIRL have anti-inflammatory effects, and unlike anti-inflammatory medications (such as NSAID’s), do not cause side effects. Studies have found that light therapy affects levels of many molecules involved in inflammation, including reactive oxygen species, reactive nitrogen species, and prostaglandins. Red and NIRL therapy have specifically shown to reduce neuroinflammation. Brain Disorders Treated by Red Light Therapy Since RL and NIRL therapy (hereafter referred to simply as “light therapy”) can positively impact the foundational pathology that characterizes so many brain disorders, it is not surprising that there is evidence to support its use in conditions ranging from Alzheimer’s Disease to traumatic brain injury. Here are the top 10 brain disorders that may benefit from RL and NIRL therapy, as supported by scientific research. Alzheimer’s Disease & Dementia Alzheimer’s Disease (AD), a form of dementia, is a neurodegenerative disease that comprises 70% of dementia cases. AD affects 1 in 10 US adults over the age of 65, or 5.7 million Americans. AD is a progressive disease that is characterized by memory loss, disorientation, behavior changes, and an eventual loss of independent functioning. Research investigating the use of light therapy for AD is extensive, with dozens of studies published in the last decade. While many studies have used light therapy in animal models of AD, several clinical trials have been published which have shown positive results. Most studies have exclusively used NIRL, which has been found to penetrate more deeply into the brain. A few studies have used unique research approaches to treating AD with light therapy. For example, a 2022 clinical trial combined light therapy to the brain with RL and NIRL therapy to the gut in patients with mild to moderate AD. The control group received sham, or placebo, light therapy. Patients receiving RL and NIRL showed improved cognitive function relative to the control group. The gut microbiome has been proven to play a role in maintaining brain health, and responds positively to light therapy. Another study combined light therapy with exercise in patients with AD. Patients in both the treatment and control groups participated in a moderate intensity exercise program 3 days per week, 45-60 minutes per session, for 3 months. Patients in the treatment group received NIRL through the nose and on wrist acupuncture points, while those in the control group received a sham light treatment. Both groups improved, but the group receiving NIRL showed more positive change. Researchers state that there are many benefits of light therapy in AD that occur on a cellular level. These include improving mitochondrial function and increasing ATP production, decreasing neuroinflammation, and decreasing oxidative stress – which have a downstream effect of decreasing brain amyloid plaque accumulation. While AD is the most common form of dementia, there is also non-Alzheimer’s dementia, which is similarly characterized by memory loss, disorientation, behavior changes, and an eventual loss of independent functioning. Although most research studies distinguish between types of dementia, some do not, and group all forms of dementia together. It’s not clear how important this distinction is, since the disorders share the same foundational pathologies, so light therapy is likely to have a similar impact regardless of the categorization of dementia. However, it’s still worth looking at some of this evidence. Mild cognitive impairment (MCI), which often progress to dementia, is also included here. A 2021 comprehensive review of dementia of all types assessed 10 studies of dementia patients treated with light therapy (either RL or NIRL). While not all studies were considered high quality, every one of them reported positive results. Included here was a study of a patient with mild dementia, as well as one of MCI. This analysis suggests that light therapy can benefit dementia starting from very early stages. Another mechanism of how light therapy affects the brain of patients with dementia was revealed in a 2021 trial. In this study, cerebral blood flow was analyzed along with cognition. In addition to improvements in cognitive function, patients also had more blood flow in several areas of the brain. The authors suggest this may be due to changes in levels of nitric oxide. Cognition In addition to improving brain health in people suffering from impaired cognitive function (such as AD, non-Alzheimer’s dementia, and MCI), light therapy has also been found to improve cognition in healthy people. This is quite remarkable, as it shows that the benefits of light therapy are quite universal. Researchers have shown in a series of controlled clinical studies that light therapy using NIRL improves cognition in young and middle-aged healthy adults when applied to the prefrontal cortex of the brain. Cognitive improvements were accompanied by changes in brain function using tools such as EEG, fMRI, and brain blood flow. In 2019, a meta-analysis of all the research looking at the effects of light therapy (including either NIRL or NIRL/RL combined) on cognition in healthy subjects was published. Seven studies included subjects aged 17 to 35 while two studies included subjects aged 49 and older. Despite some issues with study quality, the overall effect on cognition was found to be positive, leading the authors to conclude that light therapy is a “cognitive-enhancing intervention in healthy individuals”. Parkinson's Disease Parkinson’s disease (PD) is a degenerative brain disease that involves damage to dopamine producing neurons in the brain. PD involves motor symptoms (such as balance and gait problems) and non-motor symptoms (such as depression, sleep disorders, and cognitive impairment). PD affects around one million people in the US, and over 10 million people globally. Studies using light therapy to treat PD patients have shown that it is helpful. For example, one study of patients who used at-home NIRL therapy devices showed improvements in balance, fine motor skills, cognition, and mobility after 12 weeks of treatment. Patients applied the light to the head, neck, and abdomen. Research suggests that in PD, light therapy should be used 2-3 times per week for at least four weeks. Animal models of PD have been used to try to determine precisely how light therapy is working. A 2020 analysis of 28 animal studies concluded that light therapy, including both RL and NIRL, is “an effective method to treat animal models of PD”. It is suggested that these benefits are due to effects on mitochondria, oxidative stress, and brain metabolism, which may be “helping the brain to repair itself”. The effects of light therapy on mitochondria may be especially important in PD, which involves significant mitochondrial dysfunction. Stroke Stroke (Ischemic) – Ischemic stroke is a type of cardiovascular disease in which the blood flow to the brain is disrupted. Annually, close to 800 000 people have strokes in the US, with an economic cost of close to 57 billion dollars. Although some people recover fully from a stroke, it can cause permanent disability and death. The risk of stroke increases with age, but it can occur across all age groups. Light therapy has shown small, but promising, effects in studies with stroke patients. Using NIRL laser light technology, it was found that treatment improved outcomes when used within 24 hours after a stroke. A larger follow up study showed smaller effects, but there was still a positive trend towards better outcomes. Studies of animal models have shown many benefits when light therapy is used shortly after a stroke occurs. These include increasing the production of new neurons (neurogenesis), decreased inflammation, and improved mitochondrial function. The effects of light on mitochondria is very important in improving stroke outcomes, since mitochondria are responsible for protecting and maintain neurons. Light therapy may work synergistically with other non-invasive treatments for stroke, such as Coenzyme Q10. Depression Depression – Depression is a highly prevalent mood disorder, affecting at least 21 million people in the US in 2021. Depression disproportionately affects young people, with considerably higher rates in people aged 18-25. While depression is associated with psychosocial factors such as trauma, there is also often an underlying brain pathology. In particular, depression has been associated with impaired functioning of brain mitochondria, neuroinflammation, and oxidative stress. Impaired mitochondrial functioning in depression is not just limited to the brain, but rather is found throughout the body and corresponds with symptom severity. Given these associations, it is not surprising that light therapy can be used to treat depression. Several clinical trials of light therapy in depression have been conducted, all of which used NIRL applied directly to the head. A 2022 systematic review concluded that NIRL therapy “can be classified as strongly recommended for moderate grade of major depressive disorder”. Similarly, a 2023 meta-analysis concluded that there is a “promising role of in the treatment of depressive symptoms”. Multiple Sclerosis Multiple sclerosis (MS) is an autoimmune neurodegenerative disease that involves the brain and spinal cord. The prevalence of MS has recently been found to be higher than originally thought, affecting nearly 1 million people in the US. The symptoms of MS vary between affected individuals, and include fatigue, gait problems, numbness/tingling, weakness, spasticity, and vision problems. Interestingly, MS prevalence shows a north south gradient, in which people at northern latitudes have more disease. Low sun exposure is a known risk factor for MS, while greater exposure is associated with decreased disease severity. MS involves considerable neuroinflammation, as well as increased oxidative stress. Since most research related to sun exposure and MS has focused on vitamin D – which is produced from UV light, rather than RL or NIRL – there are only a few studies looking at how RL and NIRL therapy (which does not stimulate vitamin D production) affects MS. However, the research that has been done has been very positive. Notably, only one study (using a mouse model of MS) applied light therapy to the brain, with mice showing improved motor function and decreased brain pathology following treatment. Other animal studies have applied light to the spinal cord, which was also the target of a study with human MS patients. A second study of human MS patients applied light to the inside of the mouth and the radial artery on the wrist. Since MS affects both the brain and the peripheral nervous system, it appears that light therapy can target the multiple areas and still be beneficial. Autism Spectrum Disorder Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that manifests in childhood. ASD is characterized by difficulties with social interactions, abnormal language, and restricted/repetitive behaviors, interests, and activities. ASD is a term that includes a range of disorders, including both genetic and non-genetic conditions. Some people with ASD are high functioning, while others suffer from serious disability. ASD is highly prevalent, affecting 1 in 36 children in 2020. Two studies have investigated whether light therapy can be used to improve symptoms of autism. In the first, adults with high functioning ASD received transcranial PBM for 8 weeks. Treatment caused a significant improvement in social responsiveness scores, social awareness, social communication, social motivation, and restricted/repetitive behaviors. In the second, Transcranial PBM with a RL & NIRL laser was used for the treatment of irritability associated with autistic spectrum disorder in children and adolescents aged 5-17 years. Light therapy significantly reduced irritability scores compared to the placebo group, as well as lethargy and social withdrawal, stereotypic behaviour, hyperactivity and non-compliance, and inappropriate speech. Benefits were maintained at both 6 and 12 month follow up. The long-lasting benefits seen in this study are striking, and suggest that brain structure and/or function has improved as a result of treatment with RL and NIRL. Epilepsy Epilepsy is a brain disorder that causes seizures, which are discharges of electrical activity in the brain. Epilepsy affects 1.2% of the US population, or approximately 3.4 million people. Epilepsy is most commonly treated with drugs, but up to 1/3 of people do not improve with medication. Surgery is another treatment for epilepsy, but it carries some risk. Although research on light therapy and epilepsy has so far been limited to animal models, the impact of light on seizures and brain health has been positive. A 2022 review article described that “ makes the neurons ‘healthier’ by restoring their function and making them more resistant to distress and disease”. Several animal studies using NIRL have observed positive outcomes, including reduced seizure activity and decreased mortality. This is consistent with research that shows a north south disease gradient with epilepsy, similar to that observed with MS. Traumatic brain injury / concussion Traumatic brain injuries (TBI) occur when there is a violent blow to the head. Concussions are a common type of TBI. Symptoms include nausea, vomiting, vison and speech problems, and difficulty with memory and concentration. Around 1.7 million people in the US experience a TBI annually, with adolescents aged 15 to 19 and older adults over 65 years being affected more commonly. Research using light therapy (both RL and NIRL) for TBI has looked at both immediate and chronic effects in animal and human models. Animal studies have shown a reduction in the size of the brain lesion when light therapy was used immediately following trauma, which correlated with the severity of neurological symptoms. Similarly, a case study of a hockey player with a history of six documented concussions using at-home intracranial and intranasal NIRL found improved markers of health using brain imaging. Other human studies looking at behavioral outcomes have observed benefits such as improved sleep, improved cognition, and reduced anxiety and depression. Chronic Traumatic Encephalitis Chronic traumatic encephalitis (CTE) is a brain disorder caused by repeated head injuries. The injuries damage brain neurons and the condition worsens over time. CTE occurs most commonly in athletes that play contact sports, like football and boxing. CTE highlights the importance of healing traumatic brain injuries, as approximately 17% of people with repeated TBI progress to CTE. As with TBI, light therapy has been found to benefit CTE. A study of four ex-football players with suspected CTE treated with RL and NIRL to the head found that three of the four players showed improvements in outcomes including depression, pain and sleep. More research is needed to confirm these preliminary findings. Using Light Therapy for Brain Health There are an increasing number of devices on the market that directly target brain health. Most apply light therapy to the head (often as a hat or helmet), some deliver light to the brain through the nose (intranasally), some target specific areas only (such as the forehead or back of head), and some even shine light on distant areas on the body (such as the abdomen). With so many options available, how can you know which device is best for you? Here are five issues to consider. Style Preference: Your personal level of comfort with a device is important. If it isn’t easy to use, and if it doesn’t feel good on your body, you probably won’t use it consistently. Imagine yourself wearing the device – would you be comfortable wearing a hard helmet, or would you prefer a soft hat? Do you want a device that is wireless, or can you commit to being close to an electrical outlet so that you can plug it in? Do you want the flexibility of being able to lie down while wearing the device? Are you comfortable with having multiple contact points on the body, or would you prefer the device be on only one part? Think about your personal preferences and choose accordingly. Laser vs LED: Light therapy is administered using either laser or LED lights. While early light therapy research was done using lasers, LED lights have become much more popular over the last decade. The research described in this article includes both types of light sources. In 2018, Dr. Michael Hamblin – the world’s leading light therapy expert – concluded that LED lights using comparable parameters to lasers performed “equally well”, which is very important because LED powered light therapy devices can be made at a fraction of the cost of laser devices. Consumers can rest assured that using at home LED powered devices for the treatment of brain disorders is supported by research evidence. For at home use, look for a device that uses LED lights as safe and affordable option. Light Color/Wavelength: As described in this article, both RL and NIRL have been used in studies of light therapy to treat brain disorders. Although NIRL has been used most often, some studies have also found benefit from RL. Light with wavelengths between 600 and 1300nm, in the red and near infrared light spectrums, have been found to penetrate maximally into the brain. So, look for products that provide both RL and NIRL in combination, or NIRL only. Light Intensity: Light intensity refers to the amount of light being delivered by a device. It is also referred to as irradiance. The required intensity when using light therapy to impact brain disorders is unclear. The assumption is often made that for light to influence the brain, it must receive light photons, which must pass through the hair, skin, skull, and cerebrospinal fluid. Studies have found that the deepest penetration comes from higher intensity light sources using NIRL. However, studies have also shown that there are benefits to light therapy that can’t be explained by the depth of light penetration into the brain. For example, cognition and blood flow in the brain have been found to improve when light therapy is applied to the front and back of the neck. Similarly, depressive symptoms improve when light therapy is applied to either the periphery of the body, as well as directly to the brain. Although this isn’t well understand, there are several possible explanations, including effects on superficial blood and lymphatic vessels in the head and neck area as well as connections between the brain and other areas of the body, such as the gut. These “indirect” benefits to the brain from applying light therapy to somewhere on the body are increasingly being recognized as being neuroprotective. The penetration issue has led many companies to develop high intensity devices to support brain health. While these devices have been found to helpful, devices that are lower intensity have been also. Devices across a range of intensities may provide benefit, and consumers aren’t limited to a specific intensity range. Education: While light therapy education will not change the specific functionality of a device, it does have the potential to profoundly impact how someone uses the technology. When a company provides evidence-based education that teaches consumers why, how, and when to use a product, devices can be used to better support healing. Look for products with accompanying education and instructions for use, whether in printed and/or digital formats. You can also look for companies that provide support by phone or email to current or prospective customers. Conclusion Light therapy with red and near infrared light has shown great promise in supporting brain health. Benefits of treatment have been observed across a wide range of populations, ranging from young healthy adults to elderly people with dementia. Light therapy affects the foundational pathologies that underlie virtually all brain disorders, including oxidative stress, impaired metabolism, and neuroinflammation. This occurs, at least in part, through stimulation of brain mitochondria, which produce energy. Research using light therapy to support brain health has applied a range of technical specifications, including style of device, light source, light wavelength, and light intensity. Benefits have been observed in most studies, which suggests that consumers have options when it comes to choosing the device that is right for them. Factors such as comfort, cost, and ease of use can be considered. Therapy with RL and NIRL can be used to safely support brain health across the lifespan, making light therapy devices a wise investment for all. shop red light therapy head wrap For more information about Fringe light products, go to: https://fringeheals.com/shop-all-products/

Light Therapy for Inflammation
Inflammation is one of the most popular topics in healthcare, and rightfully so. It is a hallmark of many diseases currently ravaging modern society, such as arthritis, ulcerative colitis, inflammatory bowel disease, heart disease, diabetes, cancer, Alzheimer’s Disease, and depression. Inflammation is also associated with acute diseases involving the heart, pancreas, liver, and other organs, as well as trauma and infection. The personal and economic burden of these diseases cannot be overstated. Treatment of inflammation associated diseases makes up the majority of health care spending in the US, costing billions of dollars annually. There are also indirect costs of illness, such as reduced work and productivity. The most common treatments for inflammation are pharmaceuticals, including prescription (such as Celebrex) and the over-the-counter drugs (such as Aspirin and Alleve). However, many of these drugs have serious side effects, such as hypersensitivity reactions and ulcers. Given these risks, many people are turning to non-invasive therapies to fight inflammation, some of which are highly effective and have far fewer side effects than their pharmaceutical counterparts. One of these is treatment with red and near infrared light (also called red light therapy or photobiomodulation), which uses light waves at specific frequencies to decrease inflammation at a cellular level. Red Light Therapy The term “red light therapy” usually describes the use of both red and near infrared light, although only the red light produced by the device is visible to the naked eye. Infrared light can still be perceived by the body as heat when it contacts skin. Red and near infrared light therapy is the application of artificially generated light in the red and near infrared spectral bands. Red and near infrared light are naturally produced by the sun, which gives off solar radiation. The term radiation describes energy that is transmitted in the form of waves or particles. The spectrum of light in our environment consists of both light we can see (visible light) and light that our eyes can’t perceive (invisible light). This is called the electromagnetic spectrum. The visible light spectrum is quite narrow, consisting of wavelengths that range from 400 to 700nm and span from violet to red in color. Red light is part of this visible light spectrum, while near infrared light is not. While early research on light therapy used primarily lasers, more recent research has found that LED’s can also be used, which also have the advantage of applying light to a larger area of the body as well as an improved safety profile. The use of LED in red/near infrared light therapy devices has also greatly reduced the cost of treatment, making it something that can be done in the comfort of one’s own home. Inflammation The inflammatory process is mediated by the immune system, specifically the innate (or non-specific) component. Inflammation protects the body from injury and infection. There are many goals of the inflammatory response, including reducing the extent of injury, limiting the spread of infection, and restoring the body back into balance. While we mostly think of inflammation as being harmful, it’s actually a natural and essential physiological function. Inflammation becomes harmful when it is uncontrolled, lasts for a long time, or just generally occurs when it shouldn’t. There are three types of inflammation, which are mainly defined by their length. Acute inflammation is short term, lasting days. This is what happens when you sprain your ankle, and it swells up, becomes warm, and may show color changes. That response is designed to limit movement, which prevents further injury and allows the damaged tissue to heal. Sub-acute inflammation lasts from two to six weeks, and often follows acute inflammation as healing progresses. The response here is similar, but less intense, than acute inflammation. Chronic inflammation lasts for months or even years, and at this point, inflammation has ceased to be a normal (and healthy) response to a stimulus and has become pathological. Chronic inflammation is the type that is associated with most diseases. It is also associated with oxidative stress. Chronic inflammation is not associated with visible signs of inflammation (such as redness, heat, and swelling), so people often aren’t even aware it is happening. This contrasts with acute inflammation, which is usually visible and occurs because of trauma or infection. Red Light Therapy for Inflammation As described by Dr. Michael Hamblin, former Associate Professor at Harvard Medical School, “one of the most reproducible effects of is an overall reduction of inflammation”. Studies have found that light therapy affects levels of many molecules involved in inflammation, including reactive oxygen species, reactive nitrogen species, and prostaglandins. Light therapy has even been found to reduce inflammation in the brain, known as neuroinflammation. Red light therapy has been shown to have anti-inflammatory effects in the following conditions: Brain Disorders – Neuroinflammation is one of the foundational pathologies underlying a wide range of brain disorders. Light therapy has been found to decrease inflammation in Alzheimer’s Disease, as well as to improve cognitive function. Several clinical trials have been published which have shown positive results. Most studies have exclusively used near infrared light, which has been found to penetrate more deeply into the brain. Light therapy has also been found to decrease inflammation and improve recovery after a stroke. When used to treat brain disorders, light therapy is usually applied to the head area, using devices such as hats and helmets. Traumatic Brain Injury - Traumatic brain injuries (TBI) occur when there is a violent blow to the head. Approximately 17% of people with repeated TBI progress to chronic traumatic encephalitis (CTE), a brain disorder caused by repeated head injuries. Concussions are another common type of TBI. TBI’s result in acute neuroinflammation, which can become a chronic problem if not treated properly. Research using light therapy (both red and near infrared) for TBI has looked at both immediate and chronic effects in animal and human models. Animal studies have shown a reduction in the size of the brain lesion when light therapy was applied to the head immediately following trauma, which correlated with the severity of neurological symptoms, which may be due (in part) to decreased inflammation. Depression – Neuroinflammation is similarly found in people suffering from depression, and it is thought to be a key factor and therapeutic target in depressive disorders. Several clinical trials of light therapy in depression have been conducted, all of which used near infrared light applied directly to the head. A 2022 systematic review concluded that light therapy “can be classified as strongly recommended for moderate grade of major depressive disorder”. Similarly, a 2023 meta-analysis concluded that there is a “promising role of in the treatment of depressive symptoms”. Gut Disorders – Inflammatory gut diseases like colitis and inflammatory bowel diseases may benefit from red light therapy. Research has found that application of red light to the abdomen of rats with experimentally induced colitis (a form of inflammatory bowel disease) improved many markers of gut health, including reducing inflammation. There is interest in studying the use of light therapy to improve gut health in human subjects as well, with research currently ongoing to see if it helps patients with inflammatory bowel disease. When treating gut disorders, light therapy is usually applied directly to the abdomen. Pain - Pain creates a huge burden of disability, both personal and economic. There is evidence that red light therapy decreases many types of pain, including knee, neck, low-back, temporomandibular joint, and post-surgical pain. Red light therapy can also reduce pain associated with arthritis and fibromyalgia. One of the primary mechanisms of pain reduction by light therapy is by decreasing inflammation. Red light therapy also reduces pain by decreasing oxidative stress, reducing the sensitivity of neurons, and decreasing the transmission of pain related nerve impulses. Arthritis – In addition to reducing arthritis pain by decreasing inflammation, the anti-inflammatory effects of red light therapy on arthritis also yields other benefits. Inflammation in arthritis is responsible for much of the observed pathology, including cartilage breakdown. Treatment with red light therapy may have a range of positive effects, such as preserving joint function, avoiding joint deformities, and reducing drug side effects and toxicities. Delayed Onset Muscle Soreness – Delayed onset muscle soreness (DOMS) is pain that occurs in the muscles between 12 and 24 hours after a workout. DOMS is caused by tiny muscle tears that results in inflammation, which causes pain. Treatment with red light therapy to muscles after a strength training session has been shown to decrease markers of inflammation, as well as to improve other outcomes like decreased fatigue and increased protein synthesis. Injury – In addition to its anti-inflammatory effects on muscle tissue, including speeding recovery from post-exercise damage, red light therapy also reduces inflammation and speeds wound healing, such as from burn injuries. Red light therapy can also reduce inflammation and speed healing from injuries to bone, including fractures and more complex bone injuries that require the use ceramic materials. Tendon injuries also benefit from red light therapy. Skin Disorders – Many skin disorders are characterized by inflammation, including acne, psoriasis and eczema. Light therapies treat acne through anti-inflammatory and antimicrobial effects, and by decreasing the production of oil. Inflammatory acne is more responsive to light therapy than non-inflammatory acne, and studies have even found it to be superior to some medications. Red and near infrared light is also recommended in the treatment of psoriasis in part because of its anti-inflammatory effects. And in eczema, an inflammatory skin disease, treatment with near infrared light therapy has been found to decrease skin itching and lesions. Alopecia Areata – Alopecia Areata (AA) is an autoimmune disease that causes the body to attack its own hair follicles. This causes the hair to fall out, resulting in patches of baldness. AA can affect hair on any part of the body but is most common on the head. It is characterized by inflammation around hair follicles during the growth phase. The anti-inflammatory effects of light therapy may decrease this inflammation. In fact, treatment with red and near infrared light has been found to increase hair growth in bald patches. How To Use Red Light Therapy To Reduce Inflammation There is no single right way to use red light therapy to reduce inflammation. It all depends on what condition you are trying to treat and what your personal preferences are as far as treatment approach. The following are a few simple questions that can be used to guide you towards selecting the device that is most suitable for your needs: 1. What are your specific health concerns? Red light is usually applied to the affected body part, either directly in contact with the skin or at a distance of around 4 to 12 inches away. Some devices are location specific, such as knee wraps, head wraps or helmets, shoulder and neck wraps, or elbow and wrist red light wraps. Other devices are non-specific, such as square or rectangular light wraps, or red light panels. If you are dealing with a single, region-specific concern – such as knee arthritis or Alzheimer’s Disease - you may prefer to get a regionally targeted red light therapy device. However, if you are dealing with inflammation in more than one area of the body and want a device that can be used in multiple locations, a non-specific wrap may be preferable. Red light panels can also be used to address multiple body parts, although they may be difficult to position properly for some locations, such as the feet and ankles. 2. What are your preferred treatment conditions? Treatments using red light panels are most often done in a seated position, with the panel oriented towards the face, neck, torso, or other affected body part. They can also be done in a standing position, although this is not as relaxing. Lying down is possible if the treatment location allows it. Red light panels are wired and require the user to stay in the same position throughout the duration of the treatment. In contrast, treatments using red light wraps can be done in any position, including standing, sitting, and lying down. They can even be worn while moving around. Some red light wraps are wired, while others are wireless, with wireless models providing more flexibility. 3. What device specs should you look for? At home red light therapy devices almost always use LED’s as the light source. However, they do vary in other parameters, such as light wavelength(s) and intensity. When it comes to choosing the optimal wavelengths, you should look for light in the red and/or near infrared spectrums - but avoid the range of 700-780nm which has been found to be ineffective. Multi-wavelength devices including both red and near infrared light may be the most versatile. In terms of intensity, it has been found that it is ideal to mimic the intensity of the sun, which is around 24 mW/cm2 at the skin. This is described as the “sweet spot” between higher intensities, which can have harmful effects, and lower intensities, which will have no effect at all. Many devices on the market are at a much higher intensity than the sun, so choose a sun-mimicking product and don’t overdo it when it comes to treatment frequency and duration. Conclusion Red light therapy (with red and near infrared light) may be used to reduce inflammation in a wide range of diseases, both acute and chronic. There are very few contraindications to red light therapy, and it can be safely used at home as part of a regular wellness regime. Choose a device that suits your needs and preferred treatment conditions, and which delivers both red and near infrared light at an appropriate intensity. Combine red light therapy with an anti-inflammatory diet and supplements, regular exercise, stress management, and good sleep hygiene for best results.
