β-Nicotinamide Mononucleotide (NMN) is a dietary supplement and a cofactor that plays an important biochemical role in the human body. NMN is an intracellular active substance catalyzed by enzyme synthesis of niacinamide (vitamin B3 or niacin).
NMN is rapidly converted into another cofactor in the body, nicotinamide adenine dinucleotide (NAD+). NAD+ plays an important role in energy metabolism, cellular respiration and DNA repair, and NMN is an important intermediate in the synthesis of NAD+.
Studies have shown that NMN supplementation may help increase NAD+ levels. Increased levels of NAD+ are thought to be beneficial for cell metabolism, gene stability, and the aging process. Several laboratory studies and animal experiments have shown that NMN supplementation may have potential benefits in improving energy metabolism, enhancing mitochondrial function, increasing DNA repair capacity, and delaying the aging process.
NAD+ (nicotinamide adenine dinucleotide) is an important cofactor that plays an important biochemical role in cells. NAD+ plays a key role in energy metabolism processes, particularly in cellular respiration and mitochondrial function. It is involved in many metabolic pathways, including glycolysis, fatty acid oxidation and oxidative phosphorylation.
Biochemical reactions that require NAD+ / NADH include alcohol metabolism, glycolysis, gluconeogenesis, fatty acid metabolism, and the tricarboxylic acid cycle.
In addition to its role in REDOX, NAD+ is a coenzyme required for several proteins, including PARP family proteins involved in DNA repair, CD38 and CD157 proteins involved in calcium balance, and Sirtuin family proteins involved in longevity.
However, NAD+ cannot be directly absorbed by the human body, so NMN, the precursor of NAD+ that can be absorbed by the human body, has become the first choice of supplements.
