EurekAlert: After 16 weeks, the researchers measured the participants' flow-mediated dilation again and found that flow-mediated dilation had improved in the treatment group, but not in the placebo group. "This points to a beneficial effect of Vitamin D supplementation on endothelial cell function," says Dr. Harris. He adds that this is good news for African-Americans, given their risks for CVD. "If you're deficient in Vitamin D and you take supplements, you have a good probability of increasing endothelial function and therefore decreasing the risk of cardiovascular disease."
