New and Old Research on Vitamin Supplements

New and Old Research on Vitamin Supplements

A growing body of research shows that for most people with a normal diet, taking vitamins may do nothing at all -- and overdoing it can even be harmful. We explore the risks and benefits of taking your vitamins.

But a growing body of research shows that, for many people, taking supplements may do nothing at all -- and overdoing it by taking several times the recommended daily allowance can even be harmful. FDA oversight of vitamin supplements is limited, so it's up to consumers to watch what they take. We explore the risks and benefits of taking your vitamins.
