Maternal antenatal multiple micronutrient supplementation for long-term health benefits in children: a systematic review and meta-analysis.

Multiple micronutrient supplementation for pregnant women reduces low birth weight and has been recommended in low- and middle-income countries (LMICs) to improve child survival, growth and health. We aimed to review the evidence from long-term follow-up studies of multiple micronutrient supplementation beginning in the later first or second trimester.
