How to read a dietary supplement label

The U.S. Food and Drug Administration (FDA) requires that certain information appear on dietary supplement labels. By reading the label, you can get a better idea of what you are putting into your body. It's also wise to talk with your healthcare provider about whether you need a supplement and, if so, which one to choose.
