NAD+​

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and central to redox reactions and energy metabolism, a small molecule rather than a peptide. In research it is used as a reference material to study these pathways in vitro. NOX supplies NAD+ as a lyophilised research reference material for research use only; this text is educational and not human-use guidance.

NAD+ has two broad roles that make it a frequent research reference: as a redox carrier it cycles between NAD+ and NADH to move electrons through glycolysis, fatty-acid oxidation and the electron-transport chain, and as a substrate it is required by non-redox enzymes such as the sirtuins, PARPs and CD38. Because these enzymes draw on a shared NAD+ pool, the molecule is central to metabolism, DNA-repair and longevity research. NAD+ from NOX is supplied for research use only, with no medical or therapeutic claim.

NAD+ features in research on cellular energy metabolism, redox balance, DNA-repair signalling and age-related decline, tissue NAD+ levels fall with age in many organisms, typically in cell and biochemical assays that examine mechanism rather than any applied study. As with every NOX compound, NAD+ is provided as a research reference material for research use only and is not intended for human or veterinary use.

Lyophilised NAD+​ is supplied as a sealed, freeze-dried powder and is generally kept frozen and away from light, typically stored at around -20°C for long-term stability, while for shorter periods it can be kept in the fridge at 2–8°C. Keeping the vial sealed limits moisture uptake and helps preserve the dry material. This describes general laboratory handling of lyophilised research compounds and is provided for research use only, not as guidance for any other use.

NAD+​ is supplied as a lyophilised disodium salt and is reconstituted with sterile water for injection, the solvent listed on its specification, rather than the bacteriostatic water used for most peptides. The dry salt dissolves into solution so it can be handled and measured in the laboratory. This reflects general laboratory handling of research materials and is provided for research use only.

NAD+​ is supplied as a lyophilised powder in 500 mg and 1000 mg. The stated strength is the mass of compound sealed in the vial before reconstitution; the working concentration depends on the volume of solvent a researcher adds during preparation. All presentations are research reference materials supplied for research use only.

Lyophilisation freeze-dries the material into a dry powder that is considerably more stable than a solution and tolerates storage and shipping far better. This is why research compounds such as NAD+​ are supplied lyophilised and reconstituted only when a study requires. The description is educational; the material is supplied strictly for research use only.

Yes. NAD+​ is supplied by NOX strictly as a research reference material for laboratory and analytical use. It is not a medicinal product, food, cosmetic or veterinary product, and nothing in these answers should be read as guidance for human or animal use.
