I’ve written many posts where I discuss the relationship among magnesium, calcium, Vitamin D, and Vitamin Kthe magnesium factorthe calcium myth, and Vitamin K2 recommendations. Today I am going to share one of my most controversial views – you can supplement too much and/or the wrong kind of Vit D.

Too Much Vitamin D?

There’s been a lot of interest over the past few years about Vit D to the point that most doctors will do a Vit D blood test during your annual checkup.  When the results come back, your doctor says that your Vit D is too low. He/She then gives you a prescription for high dose Vit D (50,000 IU). You start using the supplements, and you may experience eye twitches, headaches, heart palpitations, or muscle spasms. What’s wrong with this picture? Aren’t vitamins supposed to make your feel better? 

I’ve been practicing medicine since 1979 and high-dose, synthetic Vit D supplementation has never made sense. Here are the reasons why:

  • When our customers start taking high-dose Vit D, many would complain that their magnesium deficiency symptoms were coming back and they didn’t know why.  
  • The standard Vit D test measures its storage form, not the active form. So, how do we know what’s really going on?
  • The body can’t possibly process incredibly high doses, like 50,000 IU, of synthetic Vit D.
  • Synthetic Vit D2 is made from irradiated fungus. Vit D3 is made from sheep wool lanolin. That’s why I recommend sunlight and/or a fermented cod liver oil for natural Vit D3.
  • Vit D is not even a vitamin but it’s really a hormone that requires magnesium to properly transform into the active form.
  • Since Vit D is a hormone with a feedback loop for calcium, when D levels are low, that can mean the body has enough calcium and doesn’t want to make more Vit D to pull in more calcium.
  • When you take high-dose Vit D, the strain on magnesium is dramatic. The accumulation of calcium is dramatic. And there are probably many other consequences that we don’t even realize.
  • A very intensive randomized, double-blind, placebo-controlled study concluded that: “Calcium and Vitamin D supplementation may cause hypercalciuria (excess calcium in the urine) and hypercalcemia (a condition in which the calcium level in your blood is above normal) in some postmenopausal women.”
  • Kidney stones have been reported in women who take calcium and Vit D supplements compared with placebo.

My Vitamin D Recommendation

My recommendation for Vit D supplementation is contained in my Supplement Recommendations– No. 9. As you can see, you can spend 30 minutes in the sunlight (You will still need magnesium to convert this Vit D to a usable form.) or 1,000-2,000 IU of Vit D3 daily. In my next post, I will talk about the product I use as well as give you a starting point for your research on Vitamin K2.

Start Your Own Exploration

In order to get the most benefit from supplementing Vit D, please make sure to supplement with ReMag so you don’t create magnesium deficiency. To start exploring the importance of this combination, please begin your research with Magnesium and Vitamin D – It Takes Two to Tango!
