However, a new paper on the risks that vitamin D may pose finally has convinced me that I was wrong. My view on vitamin supplements and the multi-billion dollar industry behind them altered radically after I began researching my book, The Diet Myth, in 2013. The industry and its PR is supported by celebrities who reportedly have high-dose vitamins drip fed into their veins, and around 50% of Americans and Britons take them regularly. But surprisingly, there is a lack of evidence to support the health benefit claims of virtually all vitamin supplements on the market.
Other pertinent points made:
However, two randomised trials found that at around 40,000 to 60,000 units per month Vitamin D effectively became a dangerous substance.
“High doses of vitamin D or those on lower doses that increased vitamin D blood levels within the optimal range (as defined by bone specialists) had a 20-30% increased rate of fractures and falls compared to those on low doses or who failed to reach “optimal blood levels”.”
“. . . low vitamin D levels are either irrelevant or merely a marker of the disease”.
“. . . our gut microbes are responsible for producing around a quarter of our vitamins and a third of our blood metabolites and also respond to changes in vitamin levels picked up by receptors in our gut lining. Any artificial addition of large amounts of chemicals will upset some sensitive immune processes”.
