Researchers in France claim that low vitamin D levels are an effect — not a cause — of disease, and recommend against supplementation.
Just when it seemed like vitamin D was the new king of dietary supplements — with benefits that include regulating blood sugar, blood pressure, immune function, pain, inflammation, and muscle strength — a recent review of hundreds of studies and clinical trials is knocking D off its throne.
The new analysis, published online this week in Lancet Diabetes and Endocrinology, found that although low vitamin D levels are associated with higher risk of a wide variety of diseases, supplementation had little impact on disease occurrence.
According to the team of researchers at the International Prevention Research Institute in Lyon, France, low vitamin D levels are likely caused by disease-related inflammation. Inflammation is associated with a wide range of diseases, which would explain why vitamin D deficiency appears linked to so many conditions.
In their report, the researchers went so far as to advise against supplementation, calling it an “ill-advised practice.”
