They are not as bioavailable because they become metabolized in passing through the stomach
Its activity intersects two major metabolic pathways simultaneously: the NAD+ biosynthesis pathway (by consuming nicotinamide, an NAD+ precursor, NNMT competes with the NAD+ salvage pathway) and the methyl-donor pathway (by consuming SAM, NNMT reduces the availability of methyl groups for epigenetic and metabolic methylation reactions)
This is faster than manual calculation and eliminates the transcription errors that happen when converting between milligrams, micrograms, milliliters, and syringe units by hand
