What the research literature covers
The characterization below reflects published research literature only. It describes what that literature examines; it is not a statement about use in people. NAD + is investigational research material and is not an approved product.
NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a naturally occurring dinucleotide coenzyme, supplied as a lyophilized powder for laboratory research use only.
It is a central redox cofactor studied extensively in mitochondrial-biology, metabolic-signalling, and cellular-senescence research. Salt forms such as the disodium salt differ in molecular weight from the free-acid value listed here.
Reported mechanism · literatureIn biochemistry NAD+ functions as a redox coenzyme that shuttles electrons via the NAD+/NADH couple, and is widely used as a defined research reagent.

NAD + and Epitalon, side by side
These two are frequently discussed together. They are different molecules, with different sequences and different molar masses. The table states what each one is and what its latest published report assayed. It does not say which is preferable for any purpose, and nothing on this site does.

Purity, and how to check it yourself
Purity here is a measurement, not a position. A report from Janoshik, an independent laboratory, is published for NAD +: net content, with no purity figure. We do not test our own material.

Enter that key at janoshik.com/verify and the laboratory returns the report it issued for this batch. You are confirming the result with them, not with us. The full certificate is published as a report image on the NAD + certificate page.
We report assayed purity and net content only. We do not run heavy-metal, microbial, endotoxin, or sterility analysis, and we do not claim it anywhere on this site.

Questions
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a naturally occurring dinucleotide coenzyme and a central redox cofactor. Ouralus supplies it as a lyophilized powder for laboratory research use only.
What is the molecular formula of NAD+?
The free-acid form is C21H27N7O14P2 (molar mass ≈ 663.4 g/mol; PubChem CID 5892, CAS 53-84-9). Salt forms such as the disodium salt have a different molecular weight.
Is NAD + third-party tested?
Yes. A report from Janoshik, an independent laboratory, is published for NAD +; it prints a measured content figure and no purity figure. Its batch field matches the lot currently shipping. The certificate carries verify key VC63IEZ7H6YF, which you can confirm directly at janoshik.com/verify.
Is NAD + an approved product?
No. NAD + is supplied strictly as a research chemical for laboratory research use only. It is not a drug, not a supplement, and not a food, and it is not for human or animal consumption.
