Maternal Supplementation With Krill Oil On Lactation : Effect Of LC-PUFA Concentration On Human Milk
Background and aimsDocosahexaenoic acid (DHA) is a major constituent of neuronal lipid bilayer and retinal membranes, thus playing a crucial role in brain and visual development of neonates. Due to the lack of enzymes for the synthesis of its precursors, dietary intakes are fundamental to provide ne...
