NAD+: Peptide Profile
Sequence, molecular data, research status and testing standards for NAD+ — written for Canadian researchers.
What Is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to cellular redox reactions, supplied as a high-purity lyophilized powder for in-vitro research.
What the Research Says About NAD+
NAD+ is an essential coenzyme in cellular energy metabolism and DNA-repair pathways. It is widely studied in ageing and metabolism research, including how NAD+ levels change over the lifespan. Strictly speaking it is a nucleotide, not a peptide, but it is commonly grouped with peptides by Canadian researchers and suppliers.
Peptide Authority summarizes published research for educational purposes only. Nothing here is medical advice or a claim that NAD+ is safe or effective for any use.
NAD+ Storage & Handling
Lyophilized (freeze-dried) NAD+ is most stable frozen at −20°C or colder for long-term storage, or refrigerated at 2–8°C for short periods. Keep vials sealed, dry and away from light, and allow them to reach room temperature before opening to prevent condensation.
What to Look for in a NAD+ Certificate of Analysis
- HPLC purity of 98–99% or higher, shown as a chromatogram with one dominant peak
- Mass spectrometry with an observed mass matching 663.4 g/mol
- A lot number that matches the label on your vial
- An independent, named laboratory and a recent test date

Is NAD+ Legal in Canada?
NAD+ is not authorized by Health Canada as a drug. It may only be sold in Canada as a research chemical for in-vitro laboratory use — not for human or animal consumption. Read how peptides are regulated in Canada.
NAD+ FAQs
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to cellular redox reactions, supplied as a high-purity lyophilized powder for in-vitro research. It is also known as β-Nicotinamide adenine dinucleotide (oxidized form).
Is NAD+ legal in Canada?
NAD+ is not authorized by Health Canada as a drug, so it cannot legally be sold for human or animal use. In Canada it is sold as a research chemical for in-vitro laboratory use only. This is general information, not legal advice.
Where can I buy NAD+ in Canada?
Peptide Authority supplies HPLC-tested, lot-coded NAD+ for research use, now serving Edmonton with Canada-wide shipping coming soon. Wherever you buy, insist on a third-party COA that matches the lot number on your vial.
How should NAD+ be stored?
Store lyophilized NAD+ frozen at −20°C for long-term stability or refrigerated at 2–8°C short-term, protected from light and moisture.
