From the Desk of Carolyn Dean MD ND

In my blog of April 11, 2024, I gave an overview of what Dr. James DiNicolantonio wrote about magnesium and the immune system. His book referenced magnesium 243 times. Another search found Vitamin D mentioned 220 times, so Dr. D. obviously thinks Vitamin D is very important. There are several chapters that feature Vitamin D and its complex functions, but in Chapter 9, DiNicolantonio tackled the question, “Should You Take a Vitamin D Supplement?”

To most of us, the importance of Vitamin D is obvious, but the supplement research funding is tainted by Big Pharma, leading to lots of “inconclusive” findings that confuse the public about this vitamin/hormone. Maybe it’s just too complex for them or maybe it’s competing with their drugs. After all, during Covid, reports showed that people with low Vitamin D had a poor outcome. People who had darker skin, which diminishes Vitamin D absorption from sunlight, had a poor outcome when infected with Covid. Since Covid I’ve seen a tremendous uptick in the number of negative supplement studies – because supplements interfere with drugs.

Controlling Supplements

I’ve seen this correlation for decades. The most egregious display was at the Codex Alimentarius meetings I attended in Bonn and Rome in 2005. Codex was designed to standardize dietary supplements and the amount of poisons allowed in foods. The actual stated purpose of controlling supplements that I heard with my ears was so that they wouldn’t interfere with prescription drugs. Case Closed!!

It seems complicated for some people, including doctors, to get the notion out of their heads that Vitamin D promotes bone growth, and if you don’t have enough, you get rickets. The research on Vitamin D is pretty recent, and doctors may have missed the memo on its importance.

Why You Should Supplement with D

Here are some facts about Vitamin D supplementation that Dr. D. wants you to know as he encourages people to supplement with this necessary nutrient:

  1. Vitamin D increases the intestinal absorption of calcium, magnesium and phosphate.
    NOTE: ReMag® doesn’t need any help with absorption. Its picometer size as a stabilized ion gives it free entry into cells. Then magnesium works to activate Vitamin D, which cannot happen without this interaction.
  1. There are different types of vitamin D – D1, D2, and D3, the last two being the most important (D2, which is called ergocalciferol, and D3 aka cholecalciferol). Vitamin D3 is about twice as potent at raising blood vitamin D levels compared to vitamin D2.
    NOTE: We think of D3 as the natural D and D2 as the synthetic D.
  1. Vitamin D3 is what our skin produces naturally when exposed to sunlight not D2.
  2. Vitamin D functions like a hormone that gets synthesized when your skin is exposed to sunlight. UVB radiation from the sun triggers a reaction that synthesizes cholesterol in your body into cholecalciferol (vitamin D3).
    NOTE: And, as mentioned about, magnesium is necessary for this biochemical process.
  1. The role of vitamin D is to regulate calcium metabolism and also control functioning of muscles and the immune system.
    NOTE: Many studies show that Vitamin D increases muscle strength. There are Vitamin D receptors in muscle fibers that may control serum calcium concentrations, directly impacting muscle contraction. Also, Vitamin D modulates inflammation that affects muscle function. This relates to the micro-damage that various forms of exercise cause and that leads to muscle growth as the muscle is repaired.
  1. Higher levels are associated with a lower risk of cardiovascular disease.
    NOTE: Even though his book is about immunity, Dr. D. mentions this strong association throughout.

The next list reflects the widespread research being conducted on Vitamin D.

  1. May reduce the risk of getting influenza in schoolchildren.
  2. Higher levels are associated with a lower risk of multiple sclerosis.
  3. May help to maintain a healthy mood.
  4. Deficiency is associated with anxiety and depression in fibromyalgia.
  5. Higher levels are associated with a lower risk of cancer.
  6. Higher levels are associated with a lower risk of Type 1 diabetes.
  7. May help with weight loss by suppressing appetite.
  8. May protect against osteoporosis and arthritis
  9. May reduce the risk of dying.
  10. Obese people have 50% less bioavailable vitamin D compared to non-obese individuals and are 3-times more likely to be deficient in vitamin D.
    NOTE: During the Covid years, obesity was listed as one of the main risk factors.

Dr. D. finishes off the chapter by reminding us that most of the population is deficient in vitamin D, both from diet and natural sunlight exposure. They don’t even get the abysmally low RDA of 600 IU. He says, like I do, that a blood test can help you decide how much Vitamin D you need to take to reach an optimum level of 60/ml (his range is 30-50).

A few years ago, when I learned that my level was 19 ng/ml, I took 10,000 IU for three months, and my level jumped to 59. Now, I take two D3K2 capsules for a total of 8,000 IU of Vitamin D.

It’s not just about vitamin D. Dr. D. also emphasizes the importance of other fat-soluble vitamins A, E, K. These vitamins not only aid in the absorption of Vitamin D but also enhance their overall benefits. In our D3K2 capsules, we’ve included K2, and we’ve packed Vitamins E and A in our Omega-3 Algae capsules, ensuring a comprehensive approach to your health.

Not in Chapter 9 but in other sections of the book, Dr. D. recommends 500mg of magnesium for the vital function of activating Vitamin D.
