Why You May Want to STOP Taking Vitamin D

Almost anyone, including your physician, says you should take Vitamin D. I say you need to know a little more in depth about vitamin D BEFORE you supplement. Ninety percent of people taking D do not need it!

Yes, this is what ALL the controversy is about with Hormone-D… getting from one state to the next!


The molecule on the Left is Calcidiol, aka 25(OH)D or the “Storage” form of the Hormone.

The molecule on the Right is Calcitriol, aka 1,25(OH)2 D3 or the “Active” form of the Hormone.

And you can’t get from Left state to Right state without consuming Magnesium and Mg-ATP… And that’s a fact.

Well, if you do nothing else today, please take the 10-min to watch this interview with Kenny L. De Meirleir, MD, PhD, a pre-eminent physiologist, internist and ME/CFS researcher based in Brussels:

He is MOST clear in his position re Hormone-D:

  • “Low 25(OH)D is just a ‘witness’ that you have too much 1,25(OH)2 D3…”  (this is ~4:30 in the video…)
  • He is critical of his professional colleagues for recommending so much “D”-pendence on this supplement…
  • He indicates the ratio of 1,25(OH)2 D3 (“Active”) to 25(OH)D (“Storage”) SHOULD BE 1.5, “maybe” 2 times greater, but what he is now finding are patients with FOUR TO FIVE TIMES (4-5X) more “Active” Hormone, compared to their “Storage” Hormone. It sets the stage for severe mineral and metabolic imbalance.

I have LOOOOONG suspected and theorized that this was, in fact, exactly what was happening, and now have clinical proof from one of the foremost authorities on this very dynamic. And why is this so alarming? Because HIGH levels of “Active” Hormone-D are indications of excess, unregulated Calcium in the blood. (And what makes it “unregulated?” — Too little Magnesium, as you no doubt imagined!…)

So, what to do?…

Please look BEFORE you “D”cide to supplement!

Conduct the following four blood tests to have certainty of your need for additional supplemental “D” — not because you read a glitzy article, or that your neighbor stressed the need, or worse yet, that your not-fully-informed doctor “ordered” you to do so. That they are choosing to overlook the metabolic foundation of this issue is a bit unsettling, at best…

The tests that get to the metabolic truth are as follows:

  • Magnesium RBC (Red Blood Cell): it’s the KEY catalyst for creating “Storage” and “Active” forms  of this Hormone…Should be 5.0-7.0 mg/dL.
  • 25(OH)D blood test: it’s the measure of the “Storage” form, the precursor to “Active” form of this Hormone…Should be 30-89 ng/dl.
  • 1,25(OH)2 D3 blood test: it’s the measure of the “Active” form of this Hormone…Should be 22-45 pg/dl.
  • “Ionized” Serum Calcium blood test (NOT a standard serum test!): given that Calcitriol’s JOB in the body is to put MORE Calcium into the blood stream, it only makes sense to know exactly how much you have there already, right?

If your Magnesium RBC is below 5 and 1, 25 (OH)2 D3 is blow 22, then and ONLY then do you need Vitamin D!

So, please, look BEFORE you take a “D”ive!

And if you need a refresher on why excess, unregulated Calcium is NOT your friend, please review this article that Carolyn Dean, MD, ND and I wrote in December, 2012:

I’m confident that this new information will be troubling to some, a bit confusing to others, but absolutely beneficial to all who take the time to read this, and act on it… I strongly encourage you to do so!

A votre sante!

    Why does Dr. Wilson suggest on his website that everyone needs vitamin d unless they eat sardines three times a week then?

    • I personally feel Dr. Wilson is wrong on this supplement. Newer research shows that vitamin D causes kidney stones, strokes, heart attacks, heart palpitations, low thyroid function, low adrenal function. It lowers potassium and raises calcium in the body and on hair mineral analysis. I ONLY give Vitamin d to about 10% of my clients who have had blood tests confirming they need it. The blood tests most Dr’s give is not the correct test to determine Vitamin D deficiency. The correct tests are listed in the article – 1,25 (OH)2 and RBC Magnsium. Only if these two tests are below the reference range do I give the hormone Vitamin D.

    • I don’t take issue with FOOD BASED Vitamin D intake. The issue is taking 5000IU a day, which I personally think is insane. This article does not talk about avoiding food. Of course you want some vitamin D in food and will make some naturally if you are in the sun.

      To advise anyone to take Vitamin D without proper testing is unwise. Vitamin D’s job is to retain calcium in the intestines.

    How do you get an ionized serum calcium test? Iv’e never heard of that. This sounds like a problem that is solved by taking all of the co factors including mg. most people are deficient.

    • There are many labs that test for ionized serum calcium. You just ask your doctor. If he’s a good doctor, he’ll have a lab that does it. I believe requestatest.com does ionized serum calcium so you can get one on your own without a doctor’s prescription.

  • kim

    Your references are in support of vitamin d supplementation.

    I wish you would write about this in more detail. I would really like to understand what you are saying here. I take very high amounts of d and have only benefited from it.


    • Remember, we are not saying NO one should take d, just that you should only take it if you need it.

  • Maryke

    How about the importance of taking vitamin K2 with D3? From what I understand, K2 makes sure the calcium and phosphorus get transported into the bones and the teeth. I had a calcification deposit on the knuckle of one of my thumbs and it disappeared after a few months of supplementation with D3, A and K complex.

  • sickofthis!

    My D,25 is 14 ng/ml..my doc wants me on supplements but I haven’t had my magnesium (serum or otherwise) checked, only my calcium which was 9.0..I do feel like I am deficient in magnesium as I am diabetic for four years without medication and have many symptoms of a mag deficiency..should I go ahead and supplement, I can’t stand to take medication or even supplements if they are not needed..and yes it was crazy not to have taken meds for the diabetes but I thought I could keep it in check with diet..but I got too comfortable and had really high numbers in the 300’s at times..but I have learned my lesson and managed much better lately with really good numbers..I have been mag deficient in the past by looking back on my numbers through my records but was never informed at the time by my doc, I only see it now on my records..what do you think? Oh, also I have a lot of other health issues like fibromyalgia high blood pressure (mostly around 140-170/88-110 with it being on the highest end when I have the doc check it, but I also have TERRIBLE anxiety most days (general, and I can HEAR the pumping of the bp cuff and i get a rush of adrenaline and anxiety) which drives my doc nuts because she can’t tell exactly what my bp is! Also have sleep apnea and am grossly overweight..I also have Raynaud’s and carpal tunnel really bad..there are other things but these are the biggest issues right now..what should I do in your opinion? Thanks so much!

  • Well, you have a really complicated case it sounds like. Everyone needs magnesium. I like magnesium glycinate 5x your body weight in pounds. High blood pressure is caused by mag deficiency.

    It also sounds like you have copper toxicity. Many times people with pain issues have excess copper in their bodies, which promotes pain syndromes like fibromyalgia. This can be helped by take systemic enzymes.

    • sickofthis!

      Okay thanks, but do you think its okay to supplement D3? The doc seems to be pushing it pretty hard!

      • I typically don’t have client supplement unless they meet to following criteria.

        1) Mag RBC (correct Reference Range: 5.0-7.0mg/dL — please totally ignore the current Ranges — OMg!)
        2) 25(OH)D — Storage Form (Calcidiol) 30-89 ng/dl
        3) 1,25(OH)2 D3 — Active Form (Calcitriol) 22-45 pg/dl
        If #1 is >6.0mg/dL AND #3 is LOW (please, just IGNORE #2…)
        Then, and ONLY THEN. take a food-based form of Hormone-D like cod liver oil.
        Indicators on a hair mineral test that they need D is fast metabolizer with high Na and K and Low Ca and Mg.

        • sickofthis!

          Okay great, my last mag was 2.1 or 2.3 maybe, so the current reference range is THAT far off!? Wow!

  • These vitamins taken in the right ratios are ok. But most people take 5000 plus IU of vitamin D without the right ratios of these vitamins. I prefer when people eat butter and other foods that have the correct ratios of these vitamins.

  • You need to take Mag glycinate, which is the form that raises RBC Magnesium. You may also have too much cell permeability. this can happen when people take too much omega-3.

    Thank you for this information. I truly wish more doctors were educated on this subject. I started seeing an alternative doctor this year for my thyroid and he placed me on 6,000 iu’s of vitamin D3 per day. At first I was seeing some good results, but then I began having horrible nausea and liver pain daily. We discovered that my calcitriol was in the 130s and as I stopped the vitamin D, the nausea has mostly subsided. But I still feel like I’m recovering from it. I was told that this is just my body, but not a common experience; however, I’m not sure that is true. Glad that you are educating people so they can make more informed decisions prior to taking vitamin D blindly and potentially running into toxicity issues like I did. Would you suggest also avoiding something like Fermented Cod Liver oil from Green Pastures until I can get things sorted out?

    • I give my clients cod liver oil. I think it’s great. It doesn’t have that much vitamin D. The goal is not to avoid all vitamin D. It’s just that in our calcified culture, we don’t need EXTRA. Food forms of D are great like butter and oily fish. so many of my clients have excess calcium in their tissues that taking D, whose job is to retain calcium in the body, is crazy. I alway advocate: Test, don’t guess. Even when it comes to vitamin D. Don’t take it unless tests show that you need it! and the 25OH most doctors are doing is NOT the tests that determines your need.
