Quest Diagnostics Health Trends™ study examines vitamin D's effect on cholesterol

A new peer-reviewed Quest Diagnostics Health Trends™ study finds that vitamin D supplementation may not improve total cholesterol and other blood lipids, key markers of risk for cardiovascular disease.

The study, by researchers at Quest Diagnostics and The Rockefeller University, is the first large-scale examination of the clinical impact of correcting vitamin D deficiency on lipid levels and associated cardiovascular-disease risk. Circulation, a peer-reviewed journal of the American Heart Association, published the study.
