Vitamin D Supplements Cut Risk for Autoimmune Disease in VITAL!
-
I'd like to talk about recent promising research from the vitamin D and omega-3 in the prevention of autoimmune diseases (VITAL) trial, recently published in The BMJ . Vitamin D 2000 IUs daily and marine omega-3 fatty acids 1 g daily in a study population of more than 25,000 US adults were applied who were older than age 50 years and were treated for more than 5 years. The main goals were the prevention of cancer and cardiovascular disease, including autoimmune diseases.

@keya vitamin D significantly reduced the risk for a composite of autoimmune disorders — a 22% significant reduction. When compared with a reference group who received double placebos (placebo for vitamin D and placebo for omega-3s), the reduction in composite autoimmune diseases was greater than 30% with vitamin D. Then accounting for latency, among those who were in the trial for at least 2 years, the reduction was closer to 40%. For the omega-3s, promising signal — about a 15% reduction.
