Daily iron and folic acid supplementation during pregnancy
It is estimated that more than 40% of pregnant women worldwide are anaemic. At least half of this anaemia burden is assumed to be due to iron deficiency.
Pregnant women require additional iron and folic acid to meet their own nutritional needs as well as those of the developing fetus. Deficiencies in iron and folic acid during pregnancy can potentially negatively impact the health of the mother, her pregnancy, as well as fetal development.
Evidence has shown that the use of iron and folic acid supplements is associated with a reduced risk of iron deficiency and anaemia in pregnant women.
Daily oral iron and folic acid supplementation is recommended as part of the antenatal care to reduce the risk of low birth weight, maternal anaemia and iron deficiency.
Additional information for this recommendation, including a suggested scheme for supplementation, can be found in the guidance summary and in the guideline, under 'WHO documents' below. This is one of several WHO recommendations on iron and folic acid supplementation. The full set of recommendations can be found in 'Full set of recommendations'.
