Don't rely on supplements to make up for an unhealthy diet. Vitamin and mineral supplements cannot replace a healthy diet. Get a Daily Food Plan for Moms that is right for you. Follow its advice for amounts to eat from each food group.
Talk with your doctor or health care provider about a vitamin and mineral supplement.
For pregnant women: Most doctors recommend that pregnant women take a vitamin and mineral supplement every day, in addition to eating a healthy diet. Doctors often recommend this for those trying to get pregnant as well. Supplements designed for pregnant women are called "prenatal supplements."
For breastfeeding women: Your nutrient needs also increase when you are breastfeeding. To meet these needs, some breastfeeding women may also need a vitamin and mineral supplement. Talk with your doctor about taking a supplement while you are breastfeeding.
