Take your vitamins.
Prenatal supplements offer vitamins and minerals that you can't always absorb from food. These nutrients serve many functions, from releasing the energy in food to building bones and normalizing heartbeat. Plus, supplements help you meet your increased folic-acid and iron needs during pregnancy. Get your doctor's approval of a supplement before taking it, and never take more than the recommended amount of any nutrient. Too much vitamin A, for instance, can cause birth defects. In addition, avoid all herbal supplements while you're pregnant.
