Dietary supplements are vitamins, herbs and minerals. Some herbs and supplements have shown to have major health benefits, such as taking folic acid while pregnant to avoid certain birth defects. But not all dietary supplements have been tested as carefully as drugs, so it’s important to understand the safety and effectiveness of dietary supplements before you take them.
