Supplementing mothers with nicotinamide riboside (NR), a precursor to NAD, led to lasting benefits for offspring in animal studies Compared with controls, pups from NR-supplemented mothers had higher lean mass, faster physical development, reduced anxiety-like behavior, and increased hippocampal neurogenesis A key driver was enhanced lactation, with NR-supplemented mothers producing more milk and transferring more calories and bioactive nutrients during early development These animal data highli
