Nicotinamide adenine dinucleotide
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to cellular energy metabolism and redox reactions — a core research reagent in metabolism, ageing and cellular-biology studies.
Both kit sizes ship within the EU — free shipping either way.
Every package is tracked — to a parcel locker or your door. We email you the tracking code as soon as it ships.
Plain, unbranded packaging. No product names, no logos — nothing on the outside indicating what is inside.
For laboratory and in vitro research use only. Not for human or veterinary use, and not for use in diagnostic procedures.
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.

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.
Mechanistic summary drawn from published literature, provided for research context only. Not a therapeutic claim.
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.
An educational summary of published literature. It is not a claim about any outcome for any buyer, and RetaNord supplies this compound for laboratory research use only.
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+ 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.
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.
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.
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.
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+.
Every RetaNord kit ships within 24–48 hours, discreetly packaged and tracked. All kits ship within the EU. For laboratory research use only.
