Iron Supplements While Pregnant

According to the March of Dimes, half of women do not have enough iron in their bodies. Pregnancy exacerbates this problem as pregnant women have increased iron needs. Iron is necessary in the production of red blood cells and oxygen delivery to the mother and the baby.

Pregnancy Needs

Iron in red blood cells helps carry oxygen to both you and your baby's organs and tissues. Due to an increased blood supply during pregnancy, iron requirements are higher for pregnant women than for non-pregnant women. The recommended daily allowance for iron in pregnancy is 27mg per day. Inadequate iron intake can lead to anemia. Anemia may lead to hemorrhaging, fatigue and decreased ability to fight infection.

Sources

Foods such as leafy greens, meat, nuts and beans are good sources of iron. Many pregnant women do not get enough iron from their diet and require a supplement. Prenatal vitamins often contain iron, but if yours doesn't, you will need an additional iron supplement. You will also need an additional iron supplement if your prenatal vitamin doesn't contain at least 27mg of iron.

Absorption

Your body's absorption of iron is increased by vitamin C, also known as ascorbic acid. Taking iron supplements with orange juice or other citrus fruits will help increase the absorption of the iron. Do not take iron with milk, coffee or tea, all of which inhibit absorption.

Side Effects

Iron supplements may cause constipation. Dividing your dose throughout the day may decrease constipation. Other ways to prevent constipation include drinking plenty of fluids and eating foods containing fiber or taking a fiber supplement. Foods high in fiber include whole grains, fruits and vegetables. Consuming a liquid iron supplement may help as well.
