NMN, known as beta nicotinamide mononucleotide, is a direct precursor of NAD+, which is rapidly converted to NAD+ in the human body to help the body maintain sufficient NAD+ and play an anti-aging role.NMN supplements may have the following advantages for the fitness population:
1. Improving muscle mass and strength: a study published in 2019 in the Journal of Nutrition reported that muscle mass and strength can be improved in older adults through NMN supplementation. This may be related to the boosting effect of NAD+ on energy metabolism and protein synthesis in muscle cells.
2. Promoting athletic performance: Another study found that athletic performance, including running speed and endurance, could be improved in mice through NMN supplementation. This may be related to the promoting effect of NAD+ on mitochondrial function.
