Jorgensen JM, et al. – This study was undertaken to assess the impact of lipid–based nutrient supplements (LNSs) on milk bioactive protein and human milk oligosaccharide (HMO) concentrations at 6 mo postpartum in women in rural Malawi. These were secondary outcomes of a previously published randomized controlled trial. Findings did not support the presumption that supplementation with an LNS or multiple micronutrient (MMN) capsule during pregnancy and postpartum would increase HMO or bioactive milk proteins at 6 mo postpartum.
