Prenatal vitamins typically contain iron. Taking a prenatal vitamin that contains iron can help prevent and treat iron deficiency anemia during pregnancy. In some cases, your health care provider might recommend a separate iron supplement. During pregnancy, you need 27 milligrams of iron a day.
Good nutrition can also prevent iron deficiency anemia during pregnancy. Dietary sources of iron include lean red meat, poultry and fish. Other options include iron-fortified breakfast cereals, dark green leafy vegetables, dried beans and peas.
The iron from animal products, such as meat, is most easily absorbed. To enhance the absorption of iron from plant sources and supplements, pair them with a food or drink high in vitamin C — such as orange juice, tomato juice or strawberries. If you take iron supplements with orange juice, avoid the calcium-fortified variety. Although calcium is an essential nutrient during pregnancy, calcium can decrease iron absorption.
