What is NAD+?
Updated October 2026
NAD+ isn't a peptide at all — it's a coenzyme that sits at the center of cellular energy metabolism, which is why it shows up constantly in longevity research.
What it is
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell. It shuttles electrons in the redox reactions that produce cellular energy and is a required cofactor for sirtuins, a family of enzymes studied heavily in aging research.
Research directions
- Cellular-metabolism and redox-balance studies
- Sirtuin-enzyme activity research
- Energy-pathway and mitochondrial-function models
