This study estimated the impact of scaling up iron-folic acid (IFA), calcium, multiple micronutrients (MMS), and balanced energy protein (BEP) supplementation for pregnant women, on human capital outcomes in low- and middle-income countries (LMIC). Results showed that across 132 LMIC, scaling up prenatal nutrition interventions to 90% coverage was estimated to increase school years and lifetime income per birth cohort by: 2.28 million y and $8.26 billion for IFA; 4.08 million y and $18.9 billion for calcium; 5.02 million y and $18.1 billion for MMS; and 0.53 million y and $1.34 billion for BEP supplementation. Therefore, increasing coverage of prenatal nutrition interventions in LMIC may lead to substantial gains in schooling and lifetime income, particularly for MMS compared to IFA.
