NAD+ — The Longevity Coenzyme at the Heart of Aging Research
NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme found in every living cell. It plays a central role in energy metabolism, DNA repair, and cellular aging — making it one of the most researched molecules in longevity science.
How It Works
- Sirtuin activation: Powers SIRT1-7 enzymes that regulate aging and gene expression
- DNA repair: Fuels PARP enzymes responsible for repairing DNA damage
- Mitochondrial function: Essential cofactor in the electron transport chain for ATP production
- Redox balance: Regulates the NAD+/NADH ratio critical for metabolic health
Research Areas
- Aging and longevity (sirtuins, telomere maintenance)
- Cognitive function and neuroprotection
- Skin aging and cellular regeneration
- Metabolic health and mitochondrial biogenesis
Why It Stands Out
NAD+ sits at the intersection of energy, aging, and cognition. As levels naturally decline with age, researchers study NAD+ replenishment as a potential strategy to understand and counteract cellular aging mechanisms.
