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.
Iron supplements are are prescribed for all pregnant patients to prevent anemia. Pregnant women should take folic acid supplements of 4 mg daily to decrease the risk for neural tube defects in the infant for a patient who takes anticonvulsant medications. Vitamin D supplements are prescribed daily, because anticonvulsant medications can interfere with production of the active form of vitamin D. Vitamin K deficiency is not seen in patients who take anticonvulsant medications; it is seen in infants exposed in utero to phenobarbital, phenytoin, and primidone.
