Prenatal vitamins are multivitamins for pregnant women or women who are trying to get pregnant. Compared to regular multivitamins, prenatal vitamins contain nutrients specifically needed for a healthy baby. During pregnancy, the baby gets all the necessary nutrients from the mother. For this reason, more nutrients are needed during pregnancy than before it. Taking prenatal vitamins is very important. Make sure that the prenatal vitamins being taken contain folic acid, iron, and calcium. Most have the right amount for each of these. Take a prenatal vitamin every day during pregnancy. If you’re planning to get pregnant, start taking prenatal vitamins before you get pregnant.
