β-Nicotinamide Mononucleotide (NMN)

β-Nicotinamide Mononucleotide (NMN)

NMN is β-nicotinamide mononucleotide. NMNAT feeds it into NAD+ salvage; research watches muscle metabolism and perceived fatigue.

Raises cellular energy

Cells hand NMN to nicotinamide mononucleotide adenylyltransferase, which joins AMP to make NAD+. NAD+ is the electron carrier for glycolysis, the citric-acid cycle, and DNA-repair enzymes; tissue NAD+ often falls with age, and daytime energy production and metabolic flexibility are the uses this salvage path is most often aimed at.

Supports muscle metabolism

Health or aging-related trials often look at grip strength, walking distance, arterial stiffness, or glucose handling. After oral absorption, NMN can be measured in blood and drives NAD metabolites up; muscle insulin sensitivity and walking endurance are the endpoints more often measured, and change usually takes several continuous weeks.
