Nicotinamide mononucleotide (NMN) is a naturally occurring compound found in small amounts in various foods, such as broccoli, cabbage, and avocado. It is a nucleotide derived from niacin (vitamin B3) and plays a crucial role in the production of NAD+, a vital molecule involved in energy metabolism and cellular repair. Research suggests that NMN may have potential health benefits, particularly in aging and metabolic disorders. By boosting NAD+ levels, NMN may help improve cellular function, enhance energy production, and support overall health. However, more studies are needed to fully understand its effects and potential therapeutic uses.
