NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell and a central player in energy metabolism. It has become a major focus of aging and metabolic research because cellular NAD+ levels decline with age. This primer summarizes the research context for educational reference only.
What is NAD+?
NAD+ is an essential coenzyme that shuttles electrons in the reactions that produce cellular energy. It also serves as a substrate for enzymes involved in DNA repair and cellular signaling. As a research compound it is supplied as a lyophilized powder.
Research focus areas
- Cellular energy: central to mitochondrial electron-transport and ATP-production research.
- DNA repair and sirtuins: a required substrate for enzymes studied in longevity research.
- Aging models: investigated because tissue NAD+ declines with age.
Handling and quality
Reconstitute lyophilized NAD+ with bacteriostatic water for research handling, and store protected from light. Confirm purity and identity through a batch-specific Certificate of Analysis before use. Browse the full research peptide catalog.
