Clinical Study Title:
Vitamin C Supplements Improve Endothelial Functioning

Plain English Summary:
There are many risk factors associated with coronary artery disease, including abnormalities in endothelium-derived nitric oxide. There has been some evidence that the use of vitamin C supplements can help to improve endothelial functioning and thus lower risk of coronary artery disease. Participants who already have coronary artery disease were given a one time dose of vitamin C, a daily supplement of vitamin C or a placebo. The function of the endothelial and brachial systems was then measured. The use of the daily vitamin C supplementation may help to maintain healthy functioning of the heart, especially for people who already have coronary artery disease.
