Vitamin D Supplements Lower Risk of Cardiovascular Events and Atrial Fibrillation in Older Adults

A clinical trial published in The BMJ suggests that vitamin D supplements may reduce the risk of major cardiovascular events, such as heart attacks, in people aged over 60. The trial involved over 21,000 Australians and found that the rate of major cardiovascular events was 9% lower in the group taking vitamin D supplements compared to the placebo group. The researchers note that the absolute risk difference was small, but further evaluation is needed, particularly in individuals taking statins or other cardiovascular disease drugs.
