About NAD+

NAD+ is a coenzyme found in every living cell, central to energy metabolism, redox chemistry and a range of signalling pathways. It is a foundational research reagent across metabolism and ageing biology. RetaNord supplies it as a lyophilized 10-vial kit in sizes from 100 mg to 1000 mg per vial.

RetaNord supplies NAD+ as fixed kits of 10 or 30 lyophilized vials, each verified at 99%+ identity purity by independent third-party HPLC (Janoshik), and every kit ships with a lot-specific Certificate of Analysis. Supplied for laboratory and in vitro research use only.

How NAD+ works

NAD+ is a coenzyme, not a peptide — nicotinamide adenine dinucleotide, present in every living cell. Its first role is as a redox carrier, cycling between NAD+ and NADH to shuttle electrons through glycolysis, the citric acid cycle and oxidative phosphorylation.

Its second role is as a consumed substrate. Sirtuins, PARPs and CD38 cleave NAD+ as part of their catalytic cycle, which links its cellular concentration to DNA repair, deacetylation signalling and calcium signalling. That consumption is why NAD+ availability, rather than just NAD+/NADH ratio, is a subject of study in its own right.

What the research shows

A 2021 review in Nature Reviews Molecular Cell Biology covers NAD+ metabolism and its role in ageing; a 2015 Science review covers the same ground across metabolism and neurodegeneration.

NAD+ is a foundational reagent rather than an investigational drug candidate — it appears in enzymology, metabolism and ageing-biology work as a standard cofactor.

Storage & handling

Sealed, lyophilized vials. 2–8 °C for routine storage; −20 °C or below for long-term. Room temperature is for transit and handling only — it is not a storage state for a compound.

Once reconstituted. Keep at 2–8 °C and never freeze — ice crystals cause irreversible damage. Reconstituted with bacteriostatic water (0.9% benzyl alcohol) a vial is commonly used within about 30 days; with plain sterile water, within 24–48 hours.

Keep vials sealed and protected from light, and minimise freeze–thaw cycles of frozen stock — each cycle costs potency.

NAD+ — questions

Do the kits come with a Certificate of Analysis?

Yes — every kit ships with a lot-specific third-party Certificate of Analysis: independent HPLC purity and content testing by Janoshik, with the batch matching your vials. View the current CoA.

Why the large mg sizes?

NAD+ is a coenzyme used at higher masses than most peptides, so vial sizes run from 100 mg up to 1000 mg. Choose the size that suits your research; the kit price updates accordingly.

Why is this sold as a 10-vial kit?

These research compounds are supplied in fixed kits of 10 identical vials — the standard research quantity. One kit (10 vials) is the minimum order to the EU.

How should NAD+ be stored?

Sealed lyophilized vials keep at 2–8 °C, or −20 °C for long-term storage. Once reconstituted, keep refrigerated and never freeze it. See storage & handling for the full detail.

How do I work out the concentration?

The volume of bacteriostatic water you add sets the concentration — the vial size alone does not. Enter your vial size and diluent volume in the reconstitution calculator to calculate the concentration for your assay.

Is NAD+ the same thing as NAD or NADH?

NAD+ and NADH are the oxidised and reduced states of the same coenzyme; “NAD” without a sign usually refers to the pair. What is supplied here is the oxidised form, NAD+.
