What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and central to metabolism. It is the electron carrier that makes redox reactions possible, and it is also consumed as a substrate by the sirtuin and PARP enzyme families — which means the cell is continuously spending it, not merely cycling it.
It is supplied as a lyophilized powder in a sealed vial. Our reconstitution guide covers technique and the reconstitution calculator works out the dilution for your target concentration.
Research context
Cellular NAD+ declines measurably with age, and that observation drives most of the research interest: models examine the consequences of depletion for mitochondrial function and sirtuin activity, and whether restoration strategies alter senescence endpoints.
Because NAD+ availability can be approached from several directions, it is often studied against compounds that act on the same pool by different routes — 5-Amino-1MQ inhibits the enzyme that diverts nicotinamide away from salvage, while MOTS-c and SS-31 act on mitochondrial function itself. Epithalon is the usual comparator in telomere-focused longevity designs.
Purity and third-party testing
Every batch is independently analysed by Testides and Peptide Test Canada and ships with a certificate of analysis reporting HPLC purity and MS identity. See how to read a certificate of analysis and what a purity figure actually means, or our Research and Quality page.
Handling and storage
NAD+ is hygroscopic and hydrolyses in solution more readily than most peptides, so it is kept dry and cold until use and reconstituted preparations are used promptly. The storage guide covers both states, and bacteriostatic vs. sterile water explains diluent choice — bacteriostatic water is stocked alongside.
