NMN is a very important precursor of coenzyme I (NAD+) in that the cells in our body use NMN to make NAD+. NDA+ plays an essential role in our body for converting the food into energy and participating many other important biological functions, such as DNA repair and cell revitalization, that are directly related to our overall health.
Chemically, NMN belongs to vitamin B3 which is a group of natural chemical compounds called niacin. These niacins include NA, NAM(nicotinamide), NR, and their derivatives, such as NMN. Niacins are all NAD+ precursors that can be converted into NAD+ through various biological pathways in human cells as shown on the left. Among all these NAD+ precursors, NMN is relatively more efficient to be convert to NAD+.
