Prenatal vitamins

To reduce your risk of having a baby with a neural tube defect (like spina bifida or anencephaly), it’s important to take a prenatal vitamin—especially during the first trimester of pregnancy. Prenatal vitamins are available over-the-counter or as a prescription from your provider. Each vitamin should contain:

Iron – 30 mg
Calcium – at least 250 mg
Folate – at least 0.6 mg
DHEA or fish oil
