Pregnant women aged 19 to 50 years should get 1,000 mg/day of calcium. Younger pregnant women need even more — 1300 mg/day.
Most women in the U.S. don’t eat enough calcium. So many pregnant women will have to change their diets to get their fill of this important mineral. Low-fat or non-fat milk, yogurt, cheese or other dairy products are great sources of calcium. Eating green leafy vegetables and calcium-fortified foods like orange juice and breakfast cereal can also provide calcium. If your diet is not providing 1,000 mg/day of calcium, talk to your doctor about taking a calcium supplement.
