NAD+

Nicotinamide adenine dinucleotide — cellular redox cofactor studied in sirtuin and mitochondrial research.

NAD+ is supplied by Bench Grade Peptides as a lyophilized powder in a sealed, lot-numbered vial, for laboratory research use only — not for human or veterinary use.

Its published Certificate of Analysis (lot 00011/0011, analyzed September 3, 2026) is from AV Analytics, a third-party laboratory, and reports 99.82% purity by HPLC; every published lot is listed on the product's COA page. Vials ship at ambient temperature in protective packaging from Florida (Bench Grade Peptides LLC is registered in Dover, Delaware), with storage notes on the lot's certificate.

NAD+ — nicotinamide adenine dinucleotide — is not a peptide at all, but a coenzyme so central to biology that no serious longevity-research catalog omits it. Every living cell uses NAD+ as the electron shuttle of energy metabolism and as the substrate for sirtuins and PARPs, the enzyme families most studied in aging biology.

Cellular NAD+ levels decline with age in essentially every tissue examined, and that decline is one of the most reproduced observations in geroscience. The research questions that follow — whether restoring NAD+ changes mitochondrial function, DNA-repair capacity, or senescence markers — drive a large and active literature.

Bench Grade supplies NAD+ as a research-grade lyophilized preparation with per-lot verification. Its molecular identity (663.43 g/mol, C21H27N7O14P2) is confirmed on every Certificate of Analysis.

Research use only. Everything on this page describes laboratory research. This compound is supplied strictly for in-vitro research use; it has not been evaluated or approved by the FDA and is not for human or veterinary use, and nothing here is a protocol or a recommendation.
