Approach again in 2014, I wrote a column about vitamin D dietary supplements, explaining that they don’t work. I added vitamin D to my earlier listing, the High 5 Nutritional vitamins That You Ought to Not Take, to create a listing of 6 ineffective vitamin dietary supplements.
Collectively, these two columns had effectively over 1,000,000 views. And but it appears the message didn’t get by. Nicely, now an enormous new research printed within the New England Journal of Medication experiences that I used to be proper all alongside: taking vitamin D drugs isn’t good for you. Let’s overview the findings, we could?
In 2014, I wrote about two research, each printed in The Lancet. The primary paper, an enormous overview of 462 different research, concluded that taking supplemental vitamin D didn’t assist to stop coronary heart illness, weight acquire, temper issues, a number of sclerosis, and metabolic issues, all of which had been linked to decrease vitamin D. Nope, they stated: it seems that low ranges of vitamin D are a outcome of unhealthy well being, not the trigger.
Ah, you is likely to be pondering, however vitamin D is usually about bone well being, proper? Nicely, the second study that I wrote about in 2014 seemed exactly at that query. That paper concluded that vitamin D dietary supplements don’t enhance bone density, and they don’t scale back the danger of osteoporosis.
In different phrases, vitamin D dietary supplements are a whole waste of cash.
Nonetheless, individuals preserve taking vitamin D, and medical doctors within the U.S. proceed to advocate it (based mostly on printed tips that urgently want revision), on a really massive scale.
So now we’ve spent tens of millions of {dollars} on an enormous new trial, which adopted almost 26,000 women and men for greater than 5 years, to see if vitamin D dietary supplements would do something to stop bone fractures. (And by “we” I imply U.S. taxpayers, who funded this research by grants from the Nationwide Institutes of Well being.)
The outcome: individuals who took vitamin D had precisely the identical danger of bone fractures as those that didn’t. It didn’t matter how a lot vitamin D they took: even these taking 1200 mg per day. And it didn’t assist individuals who had comparatively low ranges of vitamin D both. Taking vitamin D dietary supplements simply didn’t make any distinction to anybody.
So we should always cease taking vitamin D–however there’s extra. In an editorial accompanying the new study, Steven Cummings and Clifford Rosen level out that “Greater than 10 million serum 25-hydroxyvitamin D checks are carried out yearly in america.” These checks add prices to our already exorbitant well being care system, they usually don’t present sufferers with any profit.
Cummings and Rosen put it bluntly: “suppliers ought to cease screening for 25-hydroxyvitamin D ranges or recommending vitamin D dietary supplements, and other people ought to cease taking vitamin D dietary supplements to stop main ailments or lengthen life.” Or as my Hopkins Eliseo Guallar, Lawrence Appel, and Edgar Miller wrote again in 2013, “Sufficient is sufficient: cease losing cash on vitamin and mineral dietary supplements.”
On the high of this text I discussed that my listing of ineffective vitamin dietary supplements has 6 nutritional vitamins on it, so right here they’re:
- Vitamin C
- Vitamin A and beta carotene
- Vitamin E
- Vitamin B6
- Multi-vitamins
- Vitamin D

Lastly, I ought to level out {that a}lthough routine supplementation is nugatory and megadoses of nutritional vitamins could be dangerous, when you suppose you have got a vitamin deficiency, seek the advice of together with your physician. Severe vitamin deficiencies is likely to be the results of different well being issues that your physician can assist you deal with, and coverings for particular circumstances or ailments could embody nutritional vitamins.
