Vitamin D Supplements: A Promising Defense Against Cardiovascular Events

A randomized controlled trial called the D-Health Trial investigated the effects of monthly vitamin D supplementation on major cardiovascular events in older adults. The trial involved 21,315 participants aged 60-84 years and found that vitamin D supplementation might reduce the incidence of major cardiovascular events, particularly among those taking cardiovascular drugs at baseline. However, the absolute risk difference was small, and further evaluation is needed to determine the role of vitamin D supplementation in preventing or treating cardiovascular disease.
