How does NAD+ work?

Research overview of how NAD+ works at the molecular level — its proposed mechanism of action, what the published research shows, and where the gaps are.

Proposed mechanism of NAD+

A critical coenzyme involved in over 500 enzymatic reactions, researched for cellular energy production, DNA repair, and longevity pathways.

Research on NAD+ focuses on how the peptide interacts with specific biological targets in vitro and in laboratory animal models. Because NAD+ is sold strictly for research use, the mechanism is discussed here only in the context of published scientific literature — not as any suggestion of human efficacy.

What the research literature describes

Why is NAD+ important in research?

NAD+ is essential for sirtuin activation, mitochondrial function, and DNA repair. Levels decline with age, making it a key focus of longevity research.

What is the purity of Peptify NAD+?

Peptify NAD+ is 99%+ HPLC-verified with a full Certificate of Analysis provided with every batch.

How should NAD+ be stored?

Store lyophilised NAD+ at -20C for long-term stability. Reconstituted NAD+ should be kept at 2-8C.

Researchers working with NAD+ typically combine multiple analytical techniques — HPLC for purity, mass spectrometry for identity confirmation, and sometimes NMR for structural verification — before beginning any experimental protocol.

Important research limitations

Most published research on novel peptides is preclinical: conducted in cell lines, tissue samples, or animal models. Results from preclinical research do not automatically translate to human outcomes, and no peptide sold for research use is a substitute for an MHRA-approved medicine. All Peptify products are "for research use only" per UK regulations.
