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.
Generally, men and non-menstruating women should receive about 10 mg of iron daily, menstruating or nursing women 15 mg, and pregnant women 30 mg daily.
