A potentially novel target to treat obesity and type 2 diabetes is nicotinamide-N-methyltransferase (NNMT), a cytosolic enzyme with newly identified roles in cellular metabolism and energy homeostasis

Whether it's an in vitro cell study or an in vivo animal model, the desired outcomelike fat metabolism or NAD+ modulationwill dictate the appropriate concentration and administration schedule
