Description
Research Use Only. This material is supplied for in-vitro laboratory research by qualified professionals. It is not a medicine, supplement, cosmetic ingredient or veterinary product, and it is not for human or animal consumption. The research summary below describes published scientific literature; it is not a claim of effect, benefit or suitability for any person.
NAD+ (nicotinamide adenine dinucleotide) is a core coenzyme in biology. It acts as a key electron carrier and also serves as a substrate for enzymes involved in DNA repair, the control of gene expression, and a range of cell-signaling pathways. Supplied as lyophilised material for in-vitro laboratory research.
Research context
Published research on NAD+ commonly sits within areas such as cellular energy metabolism, sirtuin-related activity, DNA repair mechanisms, cellular ageing models, and neuronal cell models.
Buy NAD+ for research (EU)
NAD+ is supplied as a 500 mg lyophilised vial for in-vitro work and ships from a warehouse inside the EU, so EU addresses face no customs formalities. Standard tracked shipping takes 2–5 working days and is free over 300 €; payment methods are listed on the payment and shipping page.
What the NAD+ reports measure
Latest published result. Purity shown 99.3%, tested August 28, 2026. The NAD+ reports in the archive do not all measure the same thing. Lot XD-NJ500-PO05, tested 28 August 2026, reports purity together with identity and endotoxin. Lot GY058, tested 12 May 2026, reports content: the measured amount of NAD+ in the vial, 509.15 mg, not a purity percentage. Read that figure as milligrams per vial, not as %. Both records are in the Certificate of Analysis archive.

Frequently asked questions
What is NAD+ used for in research?
NAD+ is a research compound studied in preclinical and in-vitro literature. Peptra Labs supplies it strictly for laboratory research use only, not for human or veterinary use.
Can I buy NAD+ in Europe from Peptra Labs?
Peptra Labs supplies NAD+ to European laboratory buyers. Orders contain a sealed, clearly labelled vial, with EU shipping and online Certificate of Analysis information for each lot that has been tested. No physical Certificate of Analysis or research papers are promised inside the parcel.
Does NAD+ have a Certificate of Analysis?
Where a lot of NAD+ has been tested, its Certificate of Analysis information is published in the Peptra Labs lab reports archive. Use the online report to review the batch number, HPLC purity data, test method, and source link, then compare the batch information with the vial label. If no report is listed for your lot, none has been published yet.
What purity signals should I check for NAD+?
Check the vial label, batch number, available HPLC purity data, Certificate of Analysis source, supplier identity, storage guidance, and the absence of human-use claims. A useful supplier page should make these checks clear instead of relying on generic purity promises.
How is NAD+ stored in research labs?
Keep NAD+ sealed, protected from light and stored as stated on the label for long-term laboratory storage. After laboratory preparation for in-vitro work, follow your institution's validated handling procedure.
Human or veterinary use?
No. NAD+ from Peptra Labs is supplied strictly as laboratory research material and must not be used as a human or veterinary product.
