Stop taking Vitamin D already!

Back in 2014, I wrote a column about vitamin D supplements, explaining that they don’t work. I’ve added Vitamin D to my previous list, Top 5 Vitamins You Shouldn’t Take, to create a list of 6 useless vitamin supplements.

Together, these two columns have had over 1,000,000 views. However, it seems that the message did not arrive. Well, now a huge new study published in New England Journal of Medicine I mentioned I was right all along: Taking vitamin D pills is not good for you. Let’s review the results, shall we?

In 2014, I wrote about two studies, both of which were published in scalpel. The first paper, a comprehensive review of 462 other studies, concluded that taking vitamin D supplements did not help prevent heart disease, weight gain, mood disorders, multiple sclerosis, and metabolic disorders, all of which are linked to low vitamin D. No, they said: The lower levels of vitamin D seem to be A result From poor health, not the cause.

Ah, you might be thinking, but vitamin D is mostly about bone health, right? Well, the second study I wrote about in 2014 looked specifically at this question. That paper concluded that vitamin D supplementation does not improve bone density, nor does it reduce the risk of osteoporosis.

However, people continue to take vitamin D, and doctors in the United States continue to recommend it (based on published guidelines that need urgent review), very widely.

So we’ve now spent millions of dollars on a massive new trial, which followed nearly 26,000 men and women for more than 5 years, to see if vitamin D supplements would do anything to prevent bone fractures. (By “we,” I mean the American taxpayers, who funded this study through grants from the National Institutes of Health.)

The result: People who took vitamin D had the same risk of bone fractures as those who didn’t. It doesn’t matter how much vitamin D they took: even those taking 1,200 mg daily. It didn’t help people with relatively low levels of vitamin D either. Taking vitamin D supplements didn’t make any difference for anyone.

So we should stop taking vitamin D – but there’s more. In an editorial accompanying the new study, Stephen Cummings and Clifford Rosen note that “more than 10 million 25-hydroxyvitamin D serum tests are performed annually in the United States.” These tests add costs to our already expensive healthcare system, and provide no benefit to patients.

“Caregivers should stop checking 25-hydroxyvitamin D levels or recommending vitamin D supplements, and people should stop taking vitamin D supplements to prevent major diseases or extend life,” Cummings and Rosen said frankly. Or, as Hopkins Eliseo Goulard, Lawrence Appel, and Edgar Miller wrote to me in 2013, “Enough is enough: stop wasting money on vitamin and mineral supplements.”

At the top of this article, I mentioned that my list of unhelpful vitamin supplements contains 6 vitamins, so here they are:

  1. Vitamin C
  2. Vitamin A and beta-carotene
  3. Vitamin E
  4. Vitamin B6
  5. multi vitamins
  6. Vitamin D

If you want to know the science behind the other five, take a look at my column on the top five vitamins you shouldn’t be taking.

Finally, I must point out that aAlthough routine supplementation is worthless and large doses of vitamins can be harmful, If you think you may have a vitamin deficiency, consult your doctor. Serious vitamin deficiencies may be the result of other health problems that your doctor can help you treat, and treatments for certain conditions or diseases may include vitamins.
