Are you or someone you love suffering from depression or an autoimmune disorder? It appears vitamin D deficiency may be to blame.
Vitamin D is essential for proper immune functioning and alleviation of inflammation. The beneficial effects of vitamin D on protective immunity are due in part to its impact on the innate immune system and has numerous effects on cells within the immune system. Vitamin D is also involved in maintaining the proper balance of several minerals in the body. And, it helps to ward off the flu and many viruses and treat them. The latest research links vitamin D deficiency to many disease states. These disease states include cancer, osteoporosis, heart disease, depression, arthritis, and just about every other degenerative disease.
"Vitamin D reduces depression. In a randomized, double-blind study, People with depression who received vitamin D supplements noticed a marked improvement in their symptoms." - Journal of Internal Medicine
According to the Nutrition Research Journal, as many as 80% of people are deficient in vitamin D. Inadequate exposure to sunshine, poor eating habits, malabsorption, the VDR genetic mutation, and accelerated catabolism due to certain medications, dark skin pigment color, and too much sunscreen can be to blame.
A doctor can check vitamin D levels with a simple blood test. Many mainstream doctors will suggest that you are within normal limits if your levels are 20-30ng/mL. However, for optimal health, the Endocrine Society and many functional medicine M.D.s and naturopaths will recommend levels of between 40-70 ng/mL for both children and adults. These doctors will also recommend a more aggressive replenishment program. For example, at age five, my son's level was 24. The pediatrician recommended 500iu daily of supplementation, while our naturopath recommended 5,000iu daily for six months before retesting. Six months later, his levels were almost normal.
“Through several mechanisms, vitamin D can reduce risk of infections. Those mechanisms include inducing cathelicidins and defensins that can lower viral replication rates and reducing concentrations of pro-inflammatory cytokines that produce the inflammation that injures the lining of the lungs, leading to pneumonia, as well as increasing concentrations of anti-inflammatory cytokines” - PubMed
How to Increase Your Vitamin D Levels
Get enough sun. Vitamin D3, "the sunshine vitamin," is the only vitamin your body that is made, with the help of the sun. So be sure to get enough sun exposure to help the body make this essential nutrient. Hold off trying to protect ourselves from the rays of the sun at every turn by slathering sunscreen. Allow yourself to play outside, garden, and enjoy the rays in moderation.
If you must use some sunscreen, avoid chemical sunscreens made with toxic chemicals that cause thyroid dysfunction, endocrine disruption, allergies, organ toxicity, reproductive toxicity, skin cancer, development, brain, and metabolism problems. Shop for natural mineral-zinc-based certified products instead. When exposed to scorching climates or in the sun for extended periods, we use sunscreens by Babyganics, Badger, Babo Botanicals, and Goddess Garden products.
Eat a well-balanced diet, with foods higher in vitamin D. Although it is believed that we only get twenty percent from the foods we eat. Some foods higher in D include cod liver oil, fish, oysters, caviar, meat, eggs, and mushrooms.
Get checked for the VDR mutation. A blood test will determine if you have mutations in the vitamin D receptor. The consequence can be lower vitamin D levels and the inability to absorb vitamin calcium and many other minerals properly. According to a 2020 scientific report, supplementation of vitamin D can help improve VDR gene expression, so more supplementation may be necessary if you have this mutation.
"Something so simple. Vitamin D supplementation could improve the health status of millions and so becomes an elegant solution to many of our health problems today." – Carol L. Wagner, MD – Medical University of South Carolina
Supplementation 101. Supplementation is often critical if you cannot properly metabolize or absorb enough vitamin D or not get enough sunshine. In areas with long winters and specific populations of people with darker skin color, supplementation may be even more critical. There are many supplements on the market. However, many tablet forms are not as bioavailable and harder to absorb. Therefore, it has been recommended that liquid forms are better. In addition, liquid D is often suspended in olive oil, which helps the vitamins to absorb more easily since it is fat soluble. One of my favorite brands is by Seeking Health. It does not contain any impurities or allergy-inducing ingredients.
Boosting the immune system naturally works on your body's innate wisdom. It supports the body to operate like a well-oiled machine, protects it from unwanted pathogens and disease and helps ensure a healthy body and mind.
