NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It carries electrons in the reactions that turn nutrients into cellular energy.

What is NAD+ studied for?

NAD+ is studied in aging and cellular-energy research, including mitochondrial function, sirtuin and PARP activity, and DNA repair. Cellular NAD+ levels decline with age.

Every batch goes to an independent lab. The current batch was tested across three vials for purity (RP-HPLC), identity (LC-MS), net peptide content, endotoxins, heavy metals and sterility. Each batch's certificate of analysis is published on the lab results page.

How should NAD+ be stored?

Keep the sealed vial in the refrigerator at 36–46°F (2–8°C), dry and away from light. As a freeze-dried powder it tolerates room temperature for weeks, which is why it ships without ice. Once reconstituted, keep it refrigerated between uses. More in our guide, Do peptides need to be refrigerated?

What sizes does NAD+ come in?

NAD+ comes as a white lyophilized powder in 500mg and 1000mg vials.

Is NAD+ for human use?

No. NAD+ is sold for laboratory research use only.

NAD+ Overview

The coenzyme every cell uses to turn food into energy.

Technical overview

NAD+ is a dinucleotide: two nucleotides, one carrying adenine and one carrying nicotinamide, joined through their phosphate groups. It shuttles electrons in the reactions that produce cellular energy, switching between its oxidised form (NAD+) and reduced form (NADH).

Research applications

NAD+ is studied in aging and cellular-energy research, including mitochondrial function, sirtuin and PARP enzyme activity, DNA repair, and the decline of cellular NAD+ levels with age.
