Nicotinamide N-methyltransferase (NNMT) is a key enzyme located in the cytosolic milieu that catalyzes the transfer of methyl group from the co-factor S-(5-Adenosyl)-L-methionine (SAM) to substrates such as nicotinamide (NCA), pyridine, and related analogs, such as quinoline, isoquinoline, and the1,2,3,4 tetrahydroisoquinoline.aliphatic amine NNMT directly regulates the detoxification of endogenous and exogenous drugs/xenobiotics by the formation of methylated metabolic products, such as 1-methyl nicotinamide (1-MNA), methylated pyridiniums, and methylated related analogs
This may lead to a less efficient oxidative phosphorylation process, resulting in the production of more free radicals and reactive oxygen species (ROS) (Reid et al., 2018)

For example, a study published in 2020 found that a multivitamin containing B vitamins didnt show a statistically significant association with reduced risk of hangover symptoms in its sample
