NAD+ (nicotinamide adenine dinucleotide) is a pyridine dinucleotide coenzyme supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is NAD+ associated with?

Published preclinical laboratory work in this class concerns redox cofactor chemistry and sirtuin/PARP enzyme systems in vitro. We supply the material only; we make no representation as to any outcome, effect, or suitability for any purpose.

Is NAD+ approved for human use?

No. NAD+ is not a drug, supplement, food, cosmetic, or medical device, and has no approved human or veterinary indication. It is sold strictly for in-vitro laboratory research use by qualified professionals.

What purity is NAD+ supplied at, and how is it verified?

Each lot is assayed by HPLC and ships with its own lot-specific Certificate of Analysis, published in our COA registry. Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.

Proof, not promises. Every batch, tested by an outside lab.

Every batch of NAD+ is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot 4AXHX7: 99.90% pure by HPLC, tested by Freedom Diagnostics on 08 Oct 2026. The signed report is right here. Purity is the number the lab measured, never “at least 99” — and a batch that misses its spec never ships.

How NAD+ works

A central metabolic coenzyme studied for the cellular routes that decline with age.

Cellular energyNAD+ pools

Studied for fueling the energy metabolism that every cell depends on.

DNA repairsirtuins / PARPs

Investigated for supplying the repair enzymes (sirtuins, PARPs) that depend on NAD+.

Longevityaging hallmarks

Researched for restoring pools tied to nearly every hallmark of aging.
