Quest Diagnostics Health Trends™ study finds cholesterol levels stopped improving after 2008
Decades of declines in LDL cholesterol blood levels, a key marker of death risk from heart disease, abruptly ended in 2008, and may have stalled since, according to a multi-year, national study by Quest Diagnostics. The study, published in the peer-reviewed journal PLOS ONE, is the largest of LDL cholesterol levels in an American population, based on test results of nearly 105 million individual adult Americans.

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.
