The research team at the American Heart Association meticulously evaluated the 'body of scientific evidence' and they didn't find any clinical benefit of multivitamin and mineral use to prevent heart attacks and other cardiovascular problems.

Controversy about the effectiveness of multivitamin and mineral supplements to prevent cardiovascular diseases has been going on for years, despite numerous well-conducted research studies suggested that they don't help. The authors set out to combine the results from previously published scientific studies to help clarify the topic.
Although multivitamin and mineral supplements taken in moderation rarely cause direct harm, the study urged people to protect their heart health by understanding their individual risk for heart disease and stroke and working with a healthcare provider to create a plan that uses measures to reduce risk.
These include a heart-healthy diet, exercise, tobacco cessation, controlling blood pressure and unhealthy cholesterol levels, and when needed, medical treatment.
