Researchers conducted a systematic review to examine the health and nutrition outcomes of multiple-micronutrient (MMN) supplements with iron and folic acid (IFA) compared to IFA alone during pregnancy. They found that MMN supplements resulted in fewer babies that had low birthweight or were small-for-gestational-age; there were no significant differences between the two interventions when considering other outcomes like preterm births, stillbirth, maternal anemia in the third trimester, miscarriage, maternal mortality, perinatal or neonatal mortality, and risk of caesarean section delivery. The findings show benefits for use of MMN supplements in pregnant women.
