During pregnancy a womanâs blood volume doubles to support and nourish the growing fetus, meaning she needs even more daily iron to meet the blood count demands. A pregnant woman needs 27 milligrams of iron per day -- 30 percent more than when she's not pregnant. If you're breastfeeding, your iron needs decrease to 9 milligrams a day.
Women carrying more than one baby are at a higher risk for iron-deficiency anemia during pregnancy. Your practitioner will monitor the level of iron in your blood to make sure you're getting enough. If you're not, she may recommend that you take an extra iron supplement.
