NMN has been able to suppress age-associated weight gain, enhance energy metabolism and physical activity, improve insulin sensitivity, improve eye function, improve mitochondrial metabolism and prevent age-linked changes in gene expression

NMN is a precursor to NAD+ (Nicotinamide Adenine Dinucleotide), a crucial molecule found in every cell of the body. It plays a significant role in energy production, DNA repair, and cellular ageing. 

NMN supplementation is believed to boost NAD+ levels, which may help improve energy metabolism and cellular health.
