Nicotinamide mononucleotide (NMN) is a molecule that plays a crucial role in cellular energy production and metabolism by serving as a precursor to nicotinamide adenine dinucleotide (NAD+). NAD+ is essential for various cellular functions, including DNA repair, energy metabolism, and the regulation of circadian rhythms. As we age, NAD+ levels naturally decline, contributing to aging and age-related diseases. Supplementing with NMN has shown potential benefits in boosting NAD+ levels, which may improve energy levels, enhance cognitive function, support cardiovascular health, and promote longevity. Additionally, NMN supplementation has been linked to improved muscle function and metabolic health, making it a promising candidate for mitigating the effects of aging.
