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.
However, men 19 years of age and older need only 8 mg of iron each day, a modest amount compared to pregnant women, who require 27 mg of daily iron.The Office of Dietary Supplements advises getting your daily iron from the food you eat rather than supplements.ompared to adult women, men generally require less iron during the course of their lifetimes. Male and female infants between the ages of seven months to one year of age need 11 mg of iron each day, states the University of Maryland Medical Center, or UMMC.
