NAD+ Purity & COA Verification
For laboratory research use only. Not for human consumption, diagnosis, or treatment.
NAD+ COA and third-party testing
Every NAD+ batch is analysed by an independent laboratory before release. HPLC measures purity against a ≥99% standard, mass spectrometry confirms identity, and the published panel records heavy-metals, endotoxin and sterility screening where applicable. The NAD+ certificate of analysis is tied to the batch number printed on the vial, so the result can be verified at source rather than taken from a summary claim.
Testing documentation is supplied for laboratory research use only and does not support human, veterinary, cosmetic, diagnostic or therapeutic use.
What is NAD+?
NAD+ is nicotinamide adenine dinucleotide, a coenzyme present in every living cell. Unlike most of the catalogue, it is not a peptide: it is a dinucleotide formed from nicotinamide mononucleotide and adenosine monophosphate, and it cycles between its oxidised (NAD+) and reduced (NADH) forms as an electron carrier in redox reactions.
That redox cycling places NAD+ at the centre of cellular energy metabolism — glycolysis, the citric acid cycle and oxidative phosphorylation all depend on the NAD+/NADH pool. NAD+ is also consumed as a substrate by sirtuin and PARP enzymes, which is why published laboratory work examines it alongside mitochondrial function, metabolic flux and cellular longevity endpoints in cell and animal models.
Those references describe measurements recorded in research settings only. They do not establish an effect, benefit, anti-ageing outcome or suitability for any person, and nothing here constitutes medical, dosing or therapeutic guidance.

NAD+ research questions
+What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells. It is not a peptide — it is a dinucleotide built from nicotinamide mononucleotide and adenosine monophosphate, and it functions as an electron carrier in redox reactions that support cellular energy metabolism. It is supplied here as a research compound for laboratory use only.
+Why is NAD+ studied in research?
Published laboratory literature examines NAD+ in the context of mitochondrial function, oxidative phosphorylation, sirtuin and PARP enzyme activity, and cellular longevity endpoints in cell and animal models. These describe measurements recorded in research settings only and do not establish any effect, benefit or outcome for any person.
+Does NAD+ come with a certificate of analysis?
Yes. Every NAD+ batch is released against a third-party certificate of analysis tied to the batch number printed on the vial. You can look the batch up directly through the COA lookup on this site.
+How is NAD+ tested?
Identity and purity are confirmed by HPLC against a ≥99% standard, with mass spectrometry used to confirm identity. The published panel also records heavy-metals, endotoxin and sterility screening where applicable. Testing is performed by an independent laboratory, not in-house.
+What purity is the NAD+?
NAD+ is released to a ≥99% HPLC purity specification. The measured figure for the batch you receive is recorded on that batch's certificate of analysis rather than quoted as a generic claim.
+What vial sizes are available?
NAD+ is available in 100mg, 500mg and 1000mg lyophilised vials.
+How should NAD+ be stored?
Sealed lyophilised vials are stored refrigerated and protected from light. NAD+ is sensitive to moisture and light, so vials should be kept sealed until use and handled under standard laboratory conditions. Batch handling documentation is included.
+Where does NAD+ ship from?
NAD+ is shipped domestically within the USA with tracked delivery. Batch documentation ships with the order.
+Is NAD+ intended for human use?
No. NAD+ sold here is supplied strictly for laboratory research use. It is not for human or veterinary use, is not a drug, food or cosmetic, and has not been evaluated by the FDA for any use.

Analytical Testing Panel
Verified by Janoshik Analytical — full panel, every batch. Second independent lab confirmation is being added batch by batch.
Quantifies the main peak against related-substance peaks, so the stated purity percentage is measured rather than assumed.
Every NAD+ lot passes all 8 stages before it is released. Expand a stage to see the method and why we run it.
- Method on the COARP-HPLC (UV 214 nm)Why Ares runs it
Quantifies the main peak against related-substance peaks, so the stated purity percentage is measured rather than assumed.
- Method on the COAQuantitative HPLC mass/concentration assayWhy Ares runs it
Confirms the vial actually contains the labeled amount — purity alone says nothing about how much material is in the vial.
- Method on the COAMass Spectrometry (ESI-MS)Why Ares runs it
Confirms the measured molecular mass matches the declared compound — the check that catches a mislabeled or substituted vial.
- Method on the COAICP-MSWhy Ares runs it
Screens for elemental contaminants carried over from synthesis, reagents, or packaging.
- Method on the COAMembrane filtration, USP <71> methodologyWhy Ares runs it
Checks the finished lyophilized vial for microbial growth after fill and closure.
- Method on the COALAL assay (kinetic chromogenic)Why Ares runs it
Measures bacterial endotoxin load, a contamination marker that purity testing alone will not reveal.
- Method on the COAIndependent batch review against release specificationWhy Ares runs it
Ties the analytical numbers back to the paperwork — the lot you receive is the lot on the certificate.
- Method on the COALC-MS/MS targeted screenWhy Ares runs it
A contamination check most research suppliers never run, and the reason we run it on every batch regardless of compound.
PASS reflects the batch release standard every lot must meet before it ships. Per-lot results are published on that lot's Certificate of Analysis.
