About NAD+

NAD+ (Nicotinamide Adenine Dinucleotide) is a foundational coenzyme present in every living cell, central to redox reactions, sirtuin-mediated deacetylation, PARP-driven DNA repair and mitochondrial energy metabolism. NAD+ levels decline with age, driving intense research interest in NAD+ replenishment as a longevity and cellular-repair model. Supplied as ≥98% HPLC lyophilised powder with third-party CoA.

Research areas

  • Sirtuin activation (SIRT1/SIRT3)
  • PARP-mediated DNA repair
  • Mitochondrial redox
  • Cellular senescence
  • Longevity pathway modelling

NAD+ 500mg — mechanism, research applications & compound data

NAD+ (Nicotinamide Adenine Dinucleotide) is a foundational coenzyme central to redox metabolism, sirtuin-mediated deacetylation and PARP-driven DNA repair in every living cell. Cellular NAD+ levels decline with age, driving intense research interest in NAD+ replenishment as a longevity and cellular-repair model.

01

NAD+ research applications

The 500mg vial supports extended in-vitro and cell-culture protocols. Published research on NAD+ and its precursors (NR, NMN) covers:

  • Sirtuin activity and gene-silencing models
  • Mitochondrial function and PGC-1α expression
  • DNA-repair capacity via PARP activity
  • Cellular senescence and telomere research
  • Longevity pathway pharmacology
  • Metabolic health models
02

Storage and stability

Store the lyophilised NAD+ powder at -20°C, sealed and protected from light. NAD+ is moderately hygroscopic — allow the vial to reach room temperature before opening. Refrigerate the reconstituted solution at 2–8°C and use within 28 days.

NAD+ oxidises on prolonged exposure to air, so keep the vial sealed between draws.

03

≥98% HPLC purity verified

Every NAD+ 500mg lot is independently HPLC-UV tested to ≥98% purity by an accredited independent laboratory, with mass-spectrometry identity confirmation against the published molecular weight of 663.43 Da. The signed PDF Certificate of Analysis is supplied with every order.

References & further reading

Primary sources cited on this page

Nicotinamide adenine dinucleotide (NAD+) is a foundational cellular coenzyme that participates in redox reactions and is a required substrate for the sirtuin family of NAD+-dependent deacetylases and for poly(ADP-ribose) polymerases (PARPs) in DNA repair. Cellular NAD+ concentrations decline with age, which underpins research interest in NAD+ replenishment strategies.
