NAD+ Enhancers: The Molecular Key to Cellular Rejuvenation
The decline of nicotinamide adenine dinucleotide (NAD+) with age represents one of the most compelling targets for anti-aging interventions. As an essential coenzyme in energy metabolism and DNA repair, NAD+ depletion reaching up to 50% reduction by age 60 directly contributes to mitochondrial dysfunction, epigenetic dysregulation, and impaired sirtuin activity. Recent breakthroughs have demonstrated that…
