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.
Summary. Iron replete pregnant women often are routinely advised to take a daily supplement of 30â40 mg iron. An extensive review of controlled trials has failed to demonstrate that this practice improves clinical outcome of mother or newborn. However, this iron loading has long been assumed to be harmless.
