NMN supplements, which boost NAD levels in the body, have been shown to support aging gracefully by aiding DNA repair, fighting free radicals, and enhancing ATP production. Research led by Harvard professor David Sinclair suggests that NAD mimics the benefits of calorie restriction, activating protective genes called sirtuins to promote cell health and improve energy levels. Sinclair’s own experience with NMN supplements has led to claims of increased vitality, improved lipid profiles, and reduced fatigue, showcasing the potential of this cutting-edge anti-aging compound.
