The Link Between Vitamin D and Autoimmune Disease

AHA Publisher — Fri, 01 Apr 2022 08:04:02 +0000

Jillian Levy, CHHC via Dr. Axe – Vitamin D is a nutrient that has many roles within the immune system and central nervous system. For example, vitamin D benefits include having anti-inflammatory and immunoregulatory effects, in part by activating immune defenses and enhancing the function of immune cells (including T cells and macrophages). Higher intake of vitamin D — both from natural sunlight and food sources, plus supplements — is believed to offer protection against infections, viruses and also certain immune-related disorders. Can low vitamin D cause an autoimmune disease? Recent research suggests this might be a possibility. While vitamin D deficiency might not directly cause immune-related diseases, a link has been found between low vitamin D and autoimmune disease development. Study: Vitamin D and Autoimmune Disease A 2022 study published in the journal BMJ was conducted to determine whether or not vitamin D and omega-3 fatty acids could reduce autoimmune disease risk. The study was a randomized, double-blind, placebo-controlled trial that took place in the U.S. over the course of five-plus years and included more than 25,000 participants over the age of 50. The study concluded: Vitamin D supplementation for five years, with or without omega-3 fatty acids, helped reduce autoimmune disease by 22%. Omega-3 fatty acid supplementation, with or without vitamin D, helped reduce autoimmune disease rate by 15%. (This was considered “not statistically significant.”) Both treatments showed larger effects than placebos did. Supplementation with both vitamin D and omega-3 fatty acids helped decrease autoimmune disease by about 30% compared to taking placebos. Rheumatoid arthritis incidence was approximately 40% lower in the supplementation groups than in the placebo group. The study was designed so participants received vitamin D supplements (1,25-dihydroxyvitamin D) in doses of 2,000 IU/day or matched placebos and omega-3 fatty acids (derived from marine sources) in doses of 1,000 mg/day or matched placebos. Participants self-reported all autoimmune diseases throughout the study, which were then confirmed by medical reviews. Autoimmune diseases that were identified in participants included: rheumatoid arthritis polymyalgia rheumatica autoimmune thyroid disease psoriasis certain others For the vitamin D arm, 123 participants in the treatment group compared to 155 in the placebo group had a confirmed autoimmune disease. In the omega-3 fatty acids arm, 130 participants in the treatment group compared to 148 in the placebo group had a confirmed autoimmune disease. Within the group receiving only placebos, 88 were confirmed to have developed autoimmune diseases. Among participants who received vitamin D and omega-3 fatty acids, 63 developed autoimmune disease, while 60 who received only vitamin D and 67 who received only omega-3 fatty acids had confirmed autoimmune diseases. What It Means The BMJ study described above revealed that higher vitamin D intake had the strongest effects on helping prevent autoimmune diseases. Omega-3s also lowered risk for autoimmune problems but not quite as well as vitamin D. How does vitamin D help autoimmune diseases? Autoimmune diseases are chronic conditions characterized by inflammatory autoimmune responses to self-tissues. In other words, they occur when someone’s own immune system starts attacking the body. Vitamin D is thought to protect against autoimmune diseases via mechanisms such as: Regulating an array of genes, many involved in inflammation Suppressing inflammatory cytokines and chemokines (including C-reactive protein and IL-6) Inhibiting B cell autoantibody production and promoting monocyte differentiation into macrophages (other ways to lower inflammation) Increasing the production of anti-inflammatory regulatory T cells Can vitamin D exacerbate autoimmune disease? It’s unlikely, unless someone is taking very high amounts of vitamin D. As long as you follow guidelines, vitamin D should not worsen immune-related health problems. How much vitamin D should you take if you have an autoimmune disease? Aim for about 1,000 to 2,000 IU per day. In the study described above, adults were given 2,000 IU/day. Remember to stay consistent, since the most protective effects were found after two years of supplementation. Other Ways to Combat/Prevent Autoimmune Issues Here are other tips for supporting your immune system: Eat an anti-inflammatory diet to support gut health. Pinpoint whether you may have allergies/intolerances, such as to gluten or dairy. Reduce environmental risk factors, such as exposure to toxins, infections and stress. Get enough sleep and rest. Exercise regularly. Fight oxidative damage done by free radicals by avoiding smoking and too much alcohol. What are the best vitamins for autoimmune diseases? Experts believe that people with autoimmune diseases may benefit most from: Vitamin D Omega-3s Turmeric Glutathione L-glutamine A quality multivitamin Antioxidants, such as resveratrol (the same type found in berries and red wine) Are omega-3s good for autoimmune diseases? Do omega-3s reduce inflammation? Yes, as explained above, studies suggest higher intake of omega-3s may help protect against autoimmune disease development. It’s well-known that, generally speaking, omega-3 benefits can include fighting inflammation, supporting healthy blood flow and more. That said, supplementation with omega-3s alone did not significantly lower incidence of autoimmune disease in the BMJ study. This means you should focus on making other healthy lifestyle changes too, including improving your diet and taking vitamin D as well. On a positive note, other randomized, controlled trials of people with prevalent rheumatoid arthritis, systemic lupus and psoriasis have shown improvements in symptoms when they take omega-3s. For example, an observational study found a 49% reduction in rheumatoid arthritis risk for each 30-gram increase in daily fatty fish intake. What supplements should I avoid if I have an autoimmune disease? Be careful about using very high doses of vitamin C (too much isn’t always better), high doses of vitamin A/ beta-carotene and certain herbs on a long-term basis, such as echinacea and ginseng. These may all be helpful short term or in moderate doses, but depending on your immune system and sensitivities, you might not benefit from them when taken for long periods. Conclusion Should I take vitamin D if I have an autoimmune disease? Research suggests that yes, you should. A recent study found that vitamin D and omega-3 fatty acid supplementation had protective effects against autoimmune diseases (including rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease and psoriasis). In this large trial of older Americans, supplementation with vitamin D and omega-3s for five years were tied to a lower incidence of confirmed autoimmune disease compared to placebos. A link has especially been found between low vitamin D and autoimmune disease development because vitamin D helps fight inflammation in multiple ways. Does omega-3 suppress the immune system? No, omega-3s should help autoimmune disease symptoms in most cases, but you should still make lifestyle changes to support your immune system. To read the original article click here.

12 Easy Daily Healthy Immune Habits

AHA Publisher — Thu, 11 Nov 2021 08:00:52 +0000

Dr. Don Colbert – Each day you wake up to new experiences, challenges and opportunities. You likely think about the tasks ahead at the beginning of the day. Within that time, do you think about ways you can support your immune system? Or, healthy immune function habits that promote whole body health? If not, we have a cheat sheet for you. Here are 12 Daily Healthy Immune Habits that are easy to implement starting today. Moreover, here’s how simple habits affect immune function both positively and negatively. How Can Habits Support Immune Function? There are a few different ways lifestyle habits can affect immune function. First, they can reduce inflammatory actions and oxidative stress in the body. Next, they can activate immune cells directly. Third, they can indirectly affect your immunity. For example, high blood sugars are associated with increased infection risk (1), while controlled ones are not. Lastly, and on the other side, they can negatively impact immune function by diminishing the health of immune cells or degrading the body’s overall health. Your daily habits matter. Throughout each day, you can choose to support your immune function. Make your habit choices wisely. 12 Daily Healthy Immune Function Habits 1. GRATITUDE WHEN YOU WAKE How can you prioritize your health and immune function right when you wake up? You can be purposeful to start the day with gratitude. Whatever lies ahead in your day, you can be grateful for something or someone to start. How does this support immune health? Gratitude is one of our daily immune support habits because it can reduce stress and cortisol. Cortisol increases inflammation in the body. What’s more, gratitude can improve sleep while reducing stress. A study of 400 individuals found that writing gratitudes during the day and/or before sleep improves both the quality and duration of sleep (1). Another study found that gratitude was linked to a 10% improvement in sleep and a 19% decrease in sadness levels in patients with health issues and insomnia (2). For an extra boost, combine your time of gratitude with meditation. Focus on the moment, the day, and those things for which you are grateful. Be present in these thoughts, not thinking ahead or behind. Incredibly, this sort of mindful meditation can stimulate the immune system. Its benefits include improvements in specific markers of inflammation, cell-mediated immunity, and biological aging (3). 2. ICE-COLD SHOWER FOR BETTER IMMUNE FUNCTION Not everyone enjoys an ice-cold shower or burst of cold water in the morning. But for those who can stand it, it will support immune health! How? First, cold showers are linked to an improved immune system. A recent study from the Netherlands found that cold showers significantly reduced sick days in workers. In fact, 30 seconds or more of cold showering per day reduced sick days by 29% in the study. Additionally, more than half the participants decided to continue the cold-shower practice after the study since they were convinced by the results (4). Why would cold water improve immunity? It’s thought that cold-water-stress induces the production of catecholamines, which may play a critical role in supporting the immune system. 3. TAKE YOUR VITAMINS Specific vitamins, minerals and compounds support your immune function. While you can certainly eat foods that do so as well, supplements can bolster immunity with larger amounts of isolated nutrients. Specific immune-supporting nutrients include vitamin C, B-vitamins, elderberry, zinc, and vitamin D3 (5, 6). If you’re looking for a one-stop-shop for all of these compounds, try this supplement. Dr. Colbert’s Immune Support contains each one in amounts designed to support your immune system best. 4. GET OUTSIDE INTO THE SUNSHINE EARLY There are many benefits to getting outside. And, the earlier you do it, the better. Sunshine and time outdoors both support immune health, for free! They: Increase vitamin D production: Optimal vitamin D levels are associated with fewer seasonal illnesses. What’s more, optimal vitamin D levels support health throughout the body, from bones to skin to organs Improve melatonin levels, especially if you’re out in the early hours after waking. Why does this matter for immune function? Optimal melatonin improves sleep, and sleep is directly beneficial to the immune system Improve mood, which decreases cortisol to support healthy immune function Get outside whenever you can, and aim for early hours if possible. 5. DAILY HYDRATION FOR HEALTH AND REDUCED CORTISOL Did you know that fluid restriction and dehydration may increase cortisol in your body? This becomes especially true if you are participating in an outdoor activity (7). To reduce cortisol and therefore inflammation, hydrate your body regularly. As a bonus, you’ll promote overall cell health and skin. One recent study has shown that increasing water consumption by 2 liters per day improved skin condition and physiology, even in those who already consumed high amounts of water. The researchers concluded that this increase and improvement in skin health would likely have the most positive effect on those with lower daily water consumption (8). If you want to take the immune and health benefits even further, drink green tea for part of your daily hydration. 6. MEALS WITH IMMUNE SUPPORTING FOODS Throughout the day, choose foods that are anti-inflammatory and full of antioxidants. Vibrant fruits and vegetables, healthy fats, nuts, spices, and protein often fit the bill. Specific foods include: Fish and seafood Healthy fats such as extra virgin olive oil, avocados, MCT oil powder, and more Vibrant vegetables and small amounts of fruits Cacao, spices, and herbs such as ginger, garlic, basil, and more Potent greens and herbs like spirulina, wheatgrass, milk thistle, and more Great foods can be delicious and promote healthy immune function! 7. MOVE YOUR BODY Exercise provides a powerful 3-punch combination of immune function, health, and healthy aging. It: Modulates antioxidant and anti-inflammatory effects in the body by supporting neuroprotective action, increasing circulating of anti-inflammatory markers, and improving antioxidant defenses (9). Promotes overall body composition and healthy weights. Unhealthy weights are associated with a decline in immune function. Decreases blood glucose. High blood sugars are linked to worsened infections (1). 8. LAUGH AND ENJOY HEALTHY RELATIONSHIPS What do healthy relationships and laughter have to do with immune function and overall health? Incredibly, the Harvard Study of Adult Development has shown that good social relationships promote physical and mental health, provide a buffer against loneliness, increase longevity, and foster happiness. The Harvard Nurses’ Health Study found similar results. This means less anxiety and cortisol, and better health outcomes. Next, laughter further reduces cortisol, increases dopamine, and increases endorphins. These chemicals decrease discomfort, cortisol (10), and depressed moods (11) while elevating cellular health. 9. STARTING MID-EVENING, EMPLOY INTERMITTENT FASTING Around 7 pm in the evening, consider starting a daily intermittent fast to support your health and immune function. Amazingly, there are many documented benefits to intermittent fasting including: Immune function support (12) Improve cholesterol markers* Reduced triglyceride levels* Improved aging* Healthy weight changes without negative cellular adaptations* Reduced blood sugar abnormalities* In fact, many studies have shown that intermittent fasting supports healthy aging, brain health, heart health, and blood sugars (13). To add intermittent fasting to support immune health, aim to fast 15-16 out of the 24 hours per day. Simply finish eating dinner at 7 pm each night, and fast with only non-carbohydrate liquids (like coffee) until 10 am or so. 10. SLEEP: 7 OR MORE HOURS PER NIGHT Good quality sleep has many health and aging benefits. These include: Reduced daily cortisol* Healthy immune function* Better melatonin levels* Less depressed moods* Less inflammatory reactions* Healthy body weight* Healthy heart function* It’s a cycle. Good sleep begets good sleep, and lack of sleep increases cortisol for up to 24 hours which negatively affects sleep again (14). Lack of sleep has also been shown to reduce mental performance and alertness while increasing inflammation and cortisol (15). 11. DE-STRESS BEFORE BED Amazingly, stress and high cortisol levels can negatively affect immune function and response (22). You can fight back with an amazing all-natural stress-reducing oil. Hemp oil, specifically nano-particle oils like those in Dr. Colbert’s Nano-Science Hemp Oil, promotes health across the body’s systems while combatting stress. In fact, it’s nature’s best stress relief. It is a broad-spectrum hemp oil that is organically grown, vegan, and GMO-free. In terms of health, it have been shown to: Support healthy, stable moods (16) Promote stress relief and normalized cortisol levels Support comfortable, healthy joints (17) Encourage healthy sleep habits (18) Promote healthy skin with fewer irregularities and blemishes (19) Support healthy brain and nervous system functions (20) Encourage healthy cardiovascular functions and normalized inflammatory actions (21) 12. FAST FROM FROM DETRIMENTAL FOODS AND DETOX THE BODY REGULARLY Here’s another healthy habit with a big punch! Get rid and detox from the foods that have a negative effect on health and immune function. It’s time to reduce sweets, sugars, and refined carbohydrates, omit processed food fats like soybean oil, and help your body detox from the build-up of toxins and chemicals. How? The easiest and most effective way is to follow the Keto Zone Diet. In fact, Dr. Colbert’s Gut Zone Bookprovides a complete road map to reducing these foods, achieving a healthy weight, and supporting healthy immune function. Bottom Line Ready to support immune health every day? You can do it! These easy healthy immune function habits can be implemented together, or one at a time. Focus each day on your immune system and promote health throughout your body! To read the original article click here.
