Rating (out of 5): 5

Iron supplementation during pregnancy is strongly supported by scientific evidence. Pregnancy significantly increases a woman's need for iron, primarily because of the expansion of maternal blood volume, the needs of the developing fetus and placenta, and anticipated blood loss during delivery. Iron deficiency is the most common nutritional deficiency worldwide and is a leading cause of anemia, particularly in pregnant women. Anemia during pregnancy is associated with increased risk of preterm delivery, low birth weight, and maternal morbidity.

Numerous clinical trials and systematic reviews have demonstrated that iron supplementation prevents and treats iron-deficiency anemia in pregnancy. The World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and the American College of Obstetricians and Gynecologists (ACOG) all recommend routine iron supplementation or screening for iron status in pregnant women, especially in populations where anemia is prevalent. Oral iron (in the form of ferrous sulfate, ferrous gluconate, etc.) is the most commonly used supplement.

Historically, iron-rich foods and tonics have been recommended for pregnant women in many cultures, but the primary justification for its use is contemporary scientific validation. Randomized controlled trials confirm that supplementation improves maternal iron stores, reduces rates of anemia, and can improve pregnancy outcomes. Therefore, iron is considered an essential supplement for most pregnant women unless contraindicated.
