02Mechanism of Action
NAD+ (nicotinamide adenine dinucleotide) is a fundamental coenzyme in redox reactions, cycling between NAD+ and NADH to shuttle electrons through central metabolism. It is the rate-limiting cofactor for the sirtuin family (SIRT1–7) of deacetylases studied in cellular-aging research.
NAD+ is also consumed by PARP enzymes during DNA-damage repair and by CD38. These intersecting pathways make it a core tool in cellular-energetics and DNA-repair research.

05FAQ
What is NAD+ used for in research?
NAD+ is an essential redox coenzyme and sirtuin cofactor studied in cellular energy metabolism, DNA repair (PARP), and aging-related sirtuin research. It is sold for research use only.
What is the CAS number of NAD+?
NAD+ has CAS number 53-84-9 and a molecular weight of approximately 663.43 g/mol.
How is NAD+ stored?
NAD+ is supplied as a lyophilized powder and stored cold (2–8°C, or frozen for long-term storage) to preserve stability, with a certificate of analysis provided per lot.
How should NAD+ be stored?
NAD+ ships lyophilized and should be handled per standard research-peptide practice — kept cold, protected from light and moisture, and reconstituted only for laboratory use. Cold-chain handling is used where required. For research use only.
Is NAD+ approved for human use?
No. NAD+ is sold strictly for laboratory research use only and is not a drug or supplement. It is not approved for human or veterinary use or consumption.
How is NAD+ tested at Ethos Bio?
Every NAD+ lot is independently verified by MZ Biolabs, a third-party analytical laboratory in Arizona, on a five-point panel — RP-HPLC purity, HPLC-MS identity, endotoxin (LAL), heavy metals, and sterility. A lot-specific certificate of analysis ships with the vial. See How We Test for the full methodology.
