NMN (β-nicotinamide mononucleotide/β-nicotinamide mononu cleotide) is a derivative of vitamin B3 (nicotinamide).

Research has shown that:
NMN is a precursor of the key coenzyme NAD+ in the human body. NAD+ is an important coenzyme in the tricarboxylic acid cycle, involved in the metabolism of almost all sugars, fats and amino acids and the production of energy. NAD+ is not only an important raw material in cells, but also a key contact factor between the cell nucleus and the mitochondria responsible for energy synthesis.
