What was done
Researchers investigated postpartum changes in the maternal NAD metabolome and evaluated the effects of maternal nicotinamide riboside (NR) supplementation during nursing in an animal model. They measured maternal liver, blood, and mammary gland NAD/NADP levels, prolactin synthesis, lactation behaviors, and milk transmission of macronutrients, micronutrients, and BDNF. Offspring were assessed at weaning for glycemic control, body size, and synaptic pruning, as well as in adulthood for physical performance, anxiety-like behavior, spatial memory, behavioral immobility onset, and hippocampal neurogenesis.
What was found
Postpartum mothers showed a depressed liver NAD metabolome while circulating blood NAD metabolites supported a >20-fold increase in mammary NAD+ and NADP+. NR supplementation synergized with lactation to stimulate prolactin synthesis, mammary biosynthetic programs, and nursing behaviors, increasing the delivery of macronutrients, micronutrients, and BDNF into milk. Pups of supplemented mothers showed improved glycemic control, larger size at weaning, and enhanced synaptic pruning. As adults, offspring retained advantages in physical performance, anti-anxiety profiles, spatial memory, delayed onset of behavioral immobility, and increased adult hippocampal neurogenesis. Specific numerical values beyond the >20-fold increase in mammary NAD+/NADP+ were not reported in the abstract.
Why it matters
The study suggests maternal postgestational micronutrient supplementation can alter milk composition and produce sustained metabolic, behavioral, and neurodevelopmental benefits across offspring lifespan.
Limits
The study was conducted in animals, so findings cannot be directly assumed to apply to human lactation and infant development. The abstract does not provide sample sizes, quantitative effect estimates, confidence intervals, or specific dosing regimens.
