What is vitamin D?

Vitamin D helps your body absorb calcium. It also helps your body’s nerves, muscles, and immune system work. Your immune system protects your body from infection. Your baby needs vitamin D to help his bones and teeth grow.

During pregnancy, you need 600 IU (international units) of vitamin D each day. You can get this amount from food or your prenatal vitamin. Good sources of vitamin D include:

1. Fatty fish, like salmon
2. Milk and cereal that has vitamin D added to it (check the package label)

Your body also makes vitamin D when your skin comes in contact with sunlight. But too much sun can lead to skin aging and cancer.
