Anemia is a significant public health problem in low- and middle-income countries (LMICs). The co-existence of other micronutrient deficiencies and iron deficiency among pregnant women may be the reason for the inability to control anemia through iron and folic acid (IFA) supplementation. Multiple micronutrient supplementation (MMS) in pregnancy may help to overcome this problem. However, the recent World Health Organization (WHO) guidelines on MMS supplementation in pregnancy raised concerns regarding the adequacy of a 30mg iron dose in the MMS supplements in LMICs. The review summarized the literature to answer this question. Though most studies showed a comparable effect of MMS with 30mg iron and IFA with 60mg iron on maternal anemia outcomes, anemia persisted in the third trimester in both groups. There is a need to consider the use of a higher iron dose in MMS, especially in LMICs, to combat the problem of anemia, alongside correcting other micronutrient deficiencies.
