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.
The amount of iron prescribed by your doctor will be in milligrams (mg) of elemental iron. Most people with iron deficiency need 150-200 mg per day of elemental iron (2 to 5 mg of iron per kilogram of body weight per day). Ask your doctor how many milligrams of iron you should be taking per day. If you take vitamins, bring them to your doctor's visit to be sure. There is no evidence that any one type of iron salt, liquid, or pill is better than the others, and the amount of elemental iron varies with different preparations.
