Coenzyme Q10 (CoQ10) is a naturally occurring vitamin-like substance that has three functions of relevance to cardiovascular function: (i) its key role in the biochemical process supplying cardiac cells with energy; (ii) its role as a cell membrane protecting antioxidant; (iii) its direct effect on genes involved in inflammation and lipid metabolism. Although some CoQ10 is obtained from the diet, most is manufactured within the liver, the capacity for which declines with age. These data therefore provide a rationale for the importance of CoQ10 in cardiovascular function, and its dietary supplementation. The objective of this article is therefore to provide a brief overview of the pharmacology of CoQ10, and its role in the prevention and treatment of cardiovascular disease.
