5-amino-1mq clinical trial human NNMT Inhibitor for Research Reduced calorie diet combined with

NNMT catalyzes transfer of a methyl group from S-adenosyl-L-methionine (SAM) to nicotinamide, producing 1-methylnicotinamide (1-MNA) and S-adenosyl-L-homocysteine

The result is preserved intracellular pools of nicotinamide ( NAD+ salvage substrate) and SAM ( methyl-donor pool)

One study in diet-induced obese mice found that an NNMT inhibitor combined with a calorie-restricted diet was associated with shifts in gut bacterial populations, suggesting metabolic intervention can have knock-on effects on gut composition

There may be temporary pain and discomfort during the IM injection itself, but these tend to ease quite quickly
