NAD+: the cellular cofactor in research

NAD+ (nicotinamide adenine dinucleotide) is not a peptide but a coenzyme, and it features heavily in metabolic and longevity research. This overview explains what it is and how it is handled, with no therapeutic or dosing claims.

What it is

NAD+ is a coenzyme found in all living cells, central to the redox reactions that power cellular metabolism. In research it is studied both directly and via precursors. It is supplied as a lyophilised solid for in-vitro work.

Why it is studied

NAD+ biology is a major theme in cellular-aging and metabolic literature. As with every entry here, the findings belong to the studies and are not extended to any human context.

Handling notes

  • Reconstitute gently; NAD+ is sensitive to heat and prolonged light.
  • Keep the dry solid sealed, cold and dark.
  • Refrigerate after reconstitution and use promptly; aliquot if needed.

For in-vitro research use only. Not for human or veterinary use.
