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.
Recommended Intake. Men and women over 50 need at least 8 milligrams of iron per day, while women 50 and under need at least 18 milligrams of iron per day. You shouldn't consume more than 45 milligrams of iron per day from supplements or food, as this could cause toxicity symptoms.
