Nicotinamide Mononucleotide (NMN) is a naturally occurring compound found in small amounts in various foods, such as broccoli, cabbage, and avocado. It serves as a precursor to Nicotinamide Adenine Dinucleotide (NAD+), a vital molecule involved in energy metabolism and cellular repair. As NAD+ levels decline with age, NMN has gained attention for its potential role in promoting healthy aging and enhancing cellular function. Research suggests that NMN supplementation may help boost NAD+ levels, which could improve metabolic health and support various biological processes. While studies in animals have shown promising results, more research is needed to fully understand its effects on humans and its long-term safety.
