Magnesium & Cardiovascular Disease
Cardiovascular disease remains a leading cause of death worldwide, accounting for millions of deaths annually. Heart disease is especially prevalent in the US, where one person dies from the condition every 33 seconds. While many factors contribute to the development of cardiovascular disease, including genetics, lifestyle, and environmental influences, one critical yet often overlooked nutrient is magnesium. Shop Fringe Magnesium Magnesium & heart heath Sometimes referred to as the “forgotten electrolyte”, magnesium is a mineral that plays a critical role in maintaining cardiovascular health. Despite its importance in human physiology, magnesium deficiency is widespread, driven by dietary habits and environmental factors. It’s also very difficult to diagnose, since levels of magnesium in blood serum tend to stay within a normal range even when levels in tissues are low. In this article, we’ll explore the relationship between magnesium and cardiovascular disease, delving into the evidence, mechanisms, and practical recommendations for supplementation. What is magnesium? Magnesium is an essential mineral and electrolyte involved in over 800 enzymatic reactions in the human body. It plays a crucial role in energy production, DNA and RNA synthesis, protein synthesis, and the regulation of muscle and nerve function. Approximately 60% of the body’s magnesium is stored in bones, while the rest is distributed across muscles, soft tissues, and blood. Magnesium deficiency and inadequate intake have become increasingly prevalent, particularly in developed countries, due to both dietary habits and agricultural practices. The modern Western diet, often high in processed foods and low in magnesium-rich items like leafy greens, nuts, seeds, and whole grains, frequently fails to meet recommended magnesium levels. This dietary pattern contributes to suboptimal magnesium status in the population. Compounding this issue is the progressive depletion of magnesium in agricultural soils, a consequence of modern farming techniques such as monocropping and the extensive use of synthetic fertilizers that do not replenish essential minerals. This soil degradation leads to reduced magnesium content in crops, further diminishing dietary magnesium intake. For example, the magnesium content of vegetables has decreased by 80-90% over the last century. In epidemiological research, magnesium intakes below 200–250 mg/day are frequently associated with increased risks of cardiovascular disease. These levels are significantly below the Recommended Dietary Allowance (RDA) of 400–420 mg/day for men and 310–320 mg/day for women, highlighting the importance of adequate magnesium intake for cardiovascular health. Moreover, it has been suggested that the RDA’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. What is Cardiovascular Disease? Cardiovascular disease refers to a group of disorders affecting the heart and blood vessels. + These conditions include: Coronary artery disease: Narrowing or blockage of coronary arteries, often leading to angina or heart attacks. Stroke: A disruption of blood flow to the brain, caused by a blockage (ischemic stroke) or bleeding (hemorrhagic stroke). Hypertension: Chronic high blood pressure, a major risk factor for cardiovascular disease. Heart failure: The inability of the heart to pump blood effectively. Arrhythmias: Irregular heart rhythms that can lead to complications like stroke or cardiac arrest. Peripheral artery disease: Narrowing of blood vessels in the limbs, leading to pain and poor circulation. What is the Evidence? Magnesium's Importance for Cardiovascular Disease: Numerous clinical trials and epidemiological studies have investigated the link between magnesium and cardiovascular health. Here is a list of positive cardiovascular related outcomes that have been observed in scientific research: + Positive cardiovascular related outcomes: Blood Pressure Regulation: In clinical research, supplementation of 300–400 mg/day of magnesium significantly lowered systolic (2–4 mmHg) and diastolic (1–3 mmHg) blood pressure, particularly in individuals with hypertension. Improved Endothelial Function: In a study of patients with coronary artery disease, magnesium supplementation of 365mg/day for 6 months improved endothelial function and reduced cardiovascular risk. Improved Lipid Profiles: Research suggests that magnesium supplementation may reduce LDL cholesterol and triglycerides while increasing HDL cholesterol, which may lower atherosclerosis risk. Reduced Risk of Type 2 Diabetes: Epidemiological studies show that higher magnesium intake is associated with a lower risk of developing Type 2 diabetes. And in patients with established Type 2 diabetes, supplementation with 250mg magnesium/day for three months reduced insulin resistance and improved glycemic control. Reduced Cardiovascular Mortality: Research has shown that people who consume higher amounts of dietary magnesium have a 34% lower risk of cardiovascular mortality than low magnesium consumers. Reduced Risk of Stroke: In an analysis of studies looking at the relationship between magnesium intake and stroke, higher daily magnesium intake was linked to a reduced risk of stroke, especially in women. Mechanisms Underlying the Cardiovascular Benefits of Magnesium Since magnesium is involved in so many of the body’s physiological processes, it’s not surprising that it plays a role in several outcomes related to cardiovascular health. Here’s an overview of some of its most impactful mechanisms: + Most impactful mechanisms: Vascular Smooth Muscle Relaxation: Magnesium may promote relaxation of the muscles that line blood vessels. It also may enhance the production of nitric oxide, which helps blood vessels to dilate and reduces blood pressure. Ion Channel Stabilization: Magnesium may stabilize cardiac ion channels, which might reduce the risk of arrhythmias like atrial fibrillation and ventricular tachycardia. Prevention of Vascular Calcification: Magnesium may inhibit mineral deposits in arterial walls, reducing the vascular calcification which occurs in atherosclerosis. Reduction of Oxidative Stress: Magnesium may reduce oxidative stress by lowering the production of reactive oxygen species and supporting mitochondrial function, which might improve blood vessel health. Anti-Inflammatory Effects: Magnesium may reduce levels of molecules that promote inflammation, which might lower the risks of cardiovascular disease, insulin resistance, and diabetes. Glycemic Control and Insulin Sensitivity: Magnesium may enhance insulin signaling and glucose metabolism, which might reduce the risk of insulin resistance and diabetes, which are cardiovascular disease risk factors. Evidence-Based Recommendations for Magnesium Supplementation Based on current scientific evidence, it can be concluded that magnesium supplementation may be a valuable strategy for supporting cardiovascular health. The level of supplementation used in clinical trials of magnesium for cardiovascular health is typically in the range of 200 to 400mg. Since epidemiological studies have shown an increased risk of cardiovascular disease at levels of intake below 200 to 250mg per day, this level of supplementation would bring most people into the recommended daily intake range, leaving room for some extra based on higher body weight. When supplementing with magnesium to support cardiovascular health, it’s important to consider the form of magnesium being used. Elemental magnesium (Mg²⁺) is highly reactive and does not exist in a free, stable form. Instead, it naturally binds to other molecules, forming compounds that allow it to be absorbed and utilized by the body. Each magnesium complex will have unique properties, including differences in bioavailability and side effects (like gastrointestinal upset). Magnesium orotate, a compound consisting of magnesium and orotic acid (orotate), has gained attention for its potential cardiovascular benefits. The orotate component is thought to facilitate magnesium transport into cells, improving bioavailability and delivering additional benefits related to its metabolic and energy-enhancing properties. Research has shown that magnesium orotate may reduce hypertension and heart disease, lower the risk of heart attack, and help manage diabetes. It has also been shown to support gut and mental health, speed exercise recovery, and help with brain function in an animal model of Alzheimer’s Disease. Other forms of magnesium, including magnesium glycinate and magnesium malate, are also preferred due to their better absorption and fewer gastrointestinal side effects compared to forms such as magnesium oxide, magnesium citrate, and magnesium hydroxide. Fringe magnesium mix Fringe Magnesium Mix contains three forms of magnesium, including magnesium glycinate, magnesium malate, and the heart-friendly magnesium orotate. All three forms been shown to be better absorbed into the body, and they’re easily digested, so you don’t have to worry about the gastrointestinal issues associated with some forms of magnesium. The other ingredients in Fringe magnesium powder are all natural and include non-GMO chicory root inulin to help with dosing, organic monkfruit extract for a bit of natural sweetness, and 90mg of vitamin C for an antioxidant boost. Fringe Magnesium Mix is part of our “Essentials” line – meaning that it we recommend it for use by most people, on most days.

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 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

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.

Red Light Therapy for Gut Health
The Human Gut The human gut, also known as the gastrointestinal tract (GI tract), consists of the esophagus, stomach, small intestine, and large intestine. In simple terms, it is a tube or passageway for food that passes from the mouth to the anus. Each part of the gut has its own job to do, which is usually described as the digestion and absorption of food, and the excretion of digestive waste products. In recent years, however, a critical new role has emerged for the human gut, specifically the large intestine. As the last part of the GI tract, the large intestine receives food after most of the nutrients are absorbed and functions to reabsorb water and some remaining minerals. While this final step in the processing of food is essential, equally (if not more) important is the role of the large intestine as host to the gut microbiome, which is being described as a “major determinant of health.” The Gut Microbiome The human body contains over 150 times more genes from resident microorganisms (such as bacteria, viruses, and fungi) than from its own human cells. With a total weight of just over 2kg, microbial cells outnumber human cells by around 10 to 1. Most of these organisms went unrecognized until the last two decades. However, we now know that the body is literally teeming with invisible inhabitants, which comprise what is referred to as the human microbiome. The combined human and microbiome genome is referred to as the “holobiome”. The term “resident” is an apt descriptor when it comes to the microbiome. These organisms live inside the body, from birth to death. They also reside on the surface of the skin. And while the germ theory of disease has conditioned us to believe that most microorganisms are pathological, in fact the human microbiome is one of the most important biological predictors of health. The opposite is also true: alteration in the microbiome is an important predictor of disease. The microbiome communicates with the body, and the body communicates with the microbiome. This crosstalk is essential for human health. The human microbiome can be broken down into several divisions, based on location. The microbiome that lines the mouth is the oral microbiome; the microbiome that lines the skin is the cutaneous microbiome; the microbiome that lines the vagina is the vaginal microbiome; and the microbiome that lines the digestive tract is the gut microbiome. The gut microbiome is the most well researched biome. The role of the gut microbiome is complex and spans a wide range of diverse functions. Gut microbes are involved in the metabolism of carbohydrates, lipids, and proteins, and help to extract nutrients from food. In the gut, they produce useful molecules such as short chain fatty acids and vitamin K. Gut microbes also manufacture neurotransmitters such as serotonin, and through the gut brain axis, regulate many aspects of cognitive function. The microbiome is also involved in the metabolism of ingested drugs and toxins. The gut microbiome starts its development in utero and continues throughout the fetal period, with further colonization during delivery. Most gut microbes are acquired post partem, with breast milk as an important source in early life. A diet containing predominantly plants and whole foods is considered optimal to support the gut microbiome, with fiber being of utmost importance. Processed food, food that is high in sugar, and low fiber diets are bad for gut health. It has been recommended that dietary guidelines be revised to support a healthy gut microbiome. In addition to diet, there are several other factors that influence the health of the gut microbiome. According to the Canadian Digestive Health Association, non-dietary ways to strengthen the microbiome including: avoiding antibiotics, regularly sleeping for at least 8 hours per night, getting regular exercise, and engaging in stress reducing activities. Evidence is also accumulating that gut microbiome health can be supported by therapy with red and near infrared light. 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 Gut Health? Red light can affect gut health both through effects on the microbes in the microbiome, as well as on the gut cells of the human host. It’s hard to tease out precisely what is happening in this complex microenvironment, but one thing is clear: light therapy administered to the gut has a positive biological effect. Research has indeed shown that light can modify the microbiome. For example, when RL or NIRL 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. Bacteria have also been found to respond to the direct application of RL. Light therapy also impacts human cells. Light is absorbed in cells by molecules called chromophores, many of which are found inside the mitochondria. Mitochondria are the powerhouses of the cell, which make the energy currency of the cell known as ATP. Mitochondria are also involved in regulating the production of molecules called reactive oxygen species (ROS), which play a role in normal cellular function but can be harmful in high amounts. This is known as oxidative stress. Through its effects on mitochondria, light therapy can increase cellular energy production and modulate oxidative stress. Intestinal oxidative stress is associated with disease. Through effects on cellular metabolism and ROS production, as well as through reduction of other molecules such as reactive nitrogen species and prostaglandins, light therapy can decrease inflammation. Both RL and NIRL have anti-inflammatory effects, and unlike anti-inflammatory medications (such as NSAID’s), do not cause side effects. Inflammation is a hallmark of many gut disorders, such as Crohn’s Disease and Ulcerative Colitis. By improving the health of the gut (both the microbiome and human gut cells), a wide range of positive effects are observed, including: Improving communication between microbiome and the rest of the body. Improving digestion of food and production of energy and nutrients. Decreasing inflammation and production of reactive oxygen species. Increasing production of short chain fatty acids involved in immune function. Improving the health of the gut lining. Gut Dysbiosis When the gut microbiome is dysregulated, there is an adverse effect on its human host. This is called gut dysbiosis. Poor dietary choices, sedentary lifestyle, increased stress, and use of antibiotics (and other pharmaceuticals) can cause the gut microbiome to become unhealthy. This causes a loss of integrity of the gut lining, also known as leaky gut. In turn, the gut becomes permeable to things like microbes and food fragments, which activate the immune system and trigger an inflammatory response. Chronic inflammation ensues, and a vicious cycle is established in which the gut becomes increasingly compromised, which worsens the inflammation. Dysbiosis also impairs metabolism. Gut dysbiosis has been associated with an enormous range of human disease, including metabolic syndrome, neurological disorders, immune system disorders, autism, psychiatric disorders, obesity, systemic inflammation/autoimmunity, type 2 diabetes, chronic pain, multiple sclerosis, inflammatory bowel disease, and eye diseases. A 2021 article in The Guardian described that “The great opportunity – but also the great difficulty – of gut microbiome science is that poor gut health is associated with such a vast range of conditions.” This means that there is enormous potential to reduce human disease by improving the health of the gut microbiome, although it is important to acknowledge that our understanding of these relationships is still limited. Clinical Applications of Light Therapy to the Gut The use of light to improve health dates back thousands of years. Sunlight has been used in medicine since at least the time of the Ancient Greeks, to treat conditions such as tuberculosis, skin disorders, and bacterial and fungal infections. However, the practice fell out of favor during the 20th century as modern societies embraced the medical pharmaceutical model of therapeutics. Over the last decade, there has been an increasing interest in harnessing the power of light as a therapeutic, and a wide range of applications are being explored. Several studies have investigated what happens when RL and/or NIRL light is applied to the abdomen. Interestingly, the bulk of this research has been done using abdominally applied light to treat brain disorders, rather than for GI tract diseases. This is because of the important relationship between the gut microbiome and the brain, through a pathway known as the gut-brain axis (GBA), which involves bidirectional communication between the gut (including the microbiome) and the brain. The GBA plays an important role in brain, gut, and immune health. Alterations in the gut microbiome may be associated with disease through the GBA. RL and NIRL applied to the abdomen (as well as the neck, head and nose) of Parkinson’s disease (PD) patients has been shown to modulate the composition of the gut microbiome, with a shift towards more “healthy” bacteria. Light applied to the abdomen and neck for 12 weeks also decreased symptoms such as impaired mobility in PD patients, with improvements lasting for up to a year. PD is a degenerative brain disease that causes motor symptoms (such as balance and gait problems) and non-motor symptoms (such as depression, sleep disorders, and cognitive impairment). It affects around one million people in the US, and over 10 million people globally. Application of RL and NIRL to the abdomen (as well as the head) has also been used in the treatment of Alzheimer’s Disease (AD). In a 2022 clinical trial of patients with mild to moderate AD, those receiving light therapy showed improved cognitive function relative to the control group. 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. It has been suggested that light therapy applied to the abdomen may be useful in reducing depression. The composition of the gut microbiome has been linked to depression, with depressive patients showing higher levels of certain bacteria that are involved in the synthesis of neurotransmitters such as serotonin and GABA. These neurotransmitters are involved in the regulation of mood. Gut microbiome composition has been strongly associated with mental well-being. Given the associations between brain diseases and the GBA, it has been suggested that targeting the microbiome holds great potential in the treatment of neurodevelopmental and neurodevelopmental diseases. In addition to AD and PD, these include diseases such as multiple sclerosis, autism spectrum disorder, attention-deficit hyperactivity disorder, migraine, post-operative cognitive dysfunction, and long COVID. According to researchers from Australia, many studies are currently underway “with the aim of restoring the microbiome and potentially altering the course of these brain conditions.” Light therapy may also be helpful in modifying the microbiome in diseases that primarily affect other body systems. For example, in a case report of a patient with breast cancer, application of NIRL to the abdomen was associated with increased diversity of gut microbes, which is considered to be a healthy change. The authors suggest that light therapy may be a way to improve gut health in patients with chronic disease. Most patients with chronic disease use medications which may adversely affect gut health (especially the microbiome). There is also great potential to use light therapy to treat gut disorders. For example, animal research has found that application of RL 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. Notably, a study using NIRL applied to the abdomen (as well as the front of both thighs) is currently underway to assess whether treatment reduces pain, fatigue, and depression in patients with inflammatory bowel disease. Effects on the gut microbiome will also be measured. Using Light Therapy for Gut Health There are many light therapy devices on the market today that could be used at home to target gut health. With so many options available, how can you know which device is best for you? Here are five issues to consider. Style Preference: To treat the gut with light therapy, light should be applied to the abdominal area. Two types of devices are most appropriate for abdominal applications: (i) a light panel, or (ii) a light wrap. Your personal level of comfort with a device is important. Imagine yourself using it – Do you want to stand in front of the device, or would you prefer the flexibility of being able to lie down while wearing it? 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? 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. 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 gut disorders. Positive results have been observed when these wavelengths were used either together or individually. So, look for products that use RL and NIRL either alone or in combination. 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 gut disorders is unclear. There is variability in light intensity between studies, and no studies have directly compared different intensities. Since light is being delivered to the skin of the abdomen, it may be prudent to follow the advice given for light therapy to the skin, and mimic the intensity of the sun, which is around 24 mW/cm2. 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. Placing a high intensity device directly on the skin could be harmful. Choose a sun-mimicking product and don’t overdo it when it comes to treatment frequency and duration. 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 Hippocrates is credited with stating that “All disease begins in the gut”. While today’s science does not yet support that level of conviction, we do know that gut health is intimately associated with the overall health of the human body. We also know that “what happens in the gut doesn’t stay in the gut”, but rather influences other organs and systems through complex communication networks. The gut microbiome is inextricable from our own human gut, and both are important for optimal health. When using light therapy for gut health, it’s important to also engage in other gut-friendly activities. These include eating a gut healthy diet, staying hydrated, exercising regularly, and limiting stress. It’s advisable to work with a health care provider with expertise in this area and who can provide appropriate support. Many questions remain about how light therapy can be used to support gut health, but preliminary pre-clinical and clinical evidence supports the use of RL and NIRL both to induce healthy shifts in the gut microbiome and to decrease inflammation. Since RL and NIRL also have other effects, such as increasing energy and decreasing ROS production, many other benefits are likely to be observed. This is certain to be an area of active research interest, especially given the amazing safety profile of light therapy and the increasing availability of at-home devices.
