Can taking extra vitamins hurt you?

Vitamins and minerals aren't dangerous unless you get too much of them. It would be hard to "overdose" on vitamins or minerals that you get from the foods you eat. But if you take supplements, you can easily take too much. This is even more of a risk if you take fat-soluble vitamins.

Taking too much can also cause problems with some medical tests or get in the way of how some drugs work. It's very important to talk with your doctor before you take any vitamin and mineral pills, especially if you take prescription medicines, have any health problems or are elderly.
