    Before you decorate the nursery, pick out a name, or test-drive strollers, one item should rise to the top of your to-do list: Take a daily prenatal vitamin.

    “Ideally, you’d start taking it before you become pregnant to tune up your body with certain vitamins and minerals that you and your baby need to have a healthy pregnancy,” says Ashlesha Dayal, MD, an associate professor of obstetrics and gynecology and women’s health at Albert Einstein College of Medicine/Montefiore Medical Center.

    Since half of pregnancies are unplanned, regular prenatal vitamins ensure that you get those nutrients even before you find out that you’re expecting.

    If you already know you’re pregnant, the sooner you start taking a prenatal vitamin, the better. Even if you eat right, they’re still a good idea.

    “There are a couple of vitamins and minerals that pregnant women need more of than you can usually obtain from a healthy diet alone,” Dayal says.

    Folic Acid

    How much you need: 600 micrograms daily. The least you should get in a vitamin/supplement is 400 mcg. The rest women can usually get from their diet.

    Why you need it: Folate helps your baby’s brain and nervous system develop, which happens early in your pregnancy. And it helps prevent some birth defects. (Folate is naturally in food. Folic acid is the supplemental form.)

    You can also find it in: Dark green leafy vegetables, nuts, beans, peas, and foods fortified with folic acid such as bread, cereal, flour, pasta, and rice. But take the vitamin just in case.


    How much you need: 27 milligrams daily

    Why you need it: Iron helps your body keep up with the increase in blood that happens when you’re pregnant.

    You can also find it in: White beans, lentils, spinach, beef, cashews, chicken, and iron-fortified foods such as bread and cereal.


    How much you need: 1,000 milligrams daily

    Why you need it: Calcium is crucial to help your baby’s bones develop. Your baby will draw calcium from your own bones if he doesn’t get enough. This can you put you at risk for bone loss and breaks.

    You can also find it in: Milk, yogurt, cheese, and calcium-fortified foods such as tofu and cereal.
