Scientists explore the potential of nicotinamide mononucleotide (NMN) as an anti-aging supplement. They highlight the role of NMN in boosting NAD+ levels, which are crucial for various cellular processes and decline with age. The first source focuses on the scientific research exploring the potential of NMN in treating various age-related diseases including obesity, heart disease, and neurological disorders. The second source details the mechanisms by which NMN works, specifically its role in NAD+ biosynthesis and the activation of SIRT1, a key anti-aging protein. The third source provides a concise overview of NMN's properties, its potential benefits and risks, and its current use in the anti-aging market.
