Multivitamin and mineral supplements don’t help prevent heart attacks, strokes, or other cardiovascular events, according to a meta-analysis of 18 studies. The analysis, conducted by researchers at the Department of Medicine at the University of Alabama at Birmingham and published in Circulation: Cardiovascular Quality & Outcomes, also suggests these supplements provide no health benefits.
The studies involved more than 2 million participants total, with an average follow-up of 12 years. The researchers found no link between multivitamin and mineral supplement use and a lower risk of death from heart disease.
About 30 percent of Americans use multivitamin and mineral supplements, which rarely cause direct harm, but have been proven ineffective in a number of research studies. The American Heart Association doesn’t recommend supplements for cardiovascular disease prevention.
