This review examined studies on the use of multiple micronutrient powders (MNPs) in pregnancy, compared with supplements or no additional micronutrients. Overall, MNPs were similar to multiple micronutrient supplements in their effect on anemia and hemoglobin in mothers at or near term. The authors concluded that future trials should assess MNP adherence and evaluate the effects on birth outcomes and morbidity.
