维生素，矿物质和多种维他命剂用于心血管疾病和癌症的初级预防

Importance

Use of dietary supplements is common in the U.S. adult population. Forty-nine percent of adults used at least 1 dietary supplement between 2007 and 2010, and 32% reported using a multivitamin–multimineral supplement (1). Supplement use is more common among women and older adults than men and younger adults (2). Most dietary supplements are used to improve or maintain overall health (1). The substantial effect of cardiovascular disease and cancer on health status and mortality in the United States has been well-described (3), and many supplements are promoted to prevent these conditions (4).
