Research background
NAD+ and Cellular Energy: The Coenzyme Revolution in Aging Research
How NAD+ works as both a redox coenzyme and a consumed substrate for sirtuins, PARPs and CD38, what the evidence on age-related decline actually shows, and practical notes on using and storing NAD+ in the lab.

Overview
Biochemical Characteristics
NAD+ consists of two nucleotides joined through phosphate groups: adenine bound to ribose phosphate connected to nicotinamide riboside phosphate. The nicotinamide ring undergoes reversible reduction to NADH, enabling its function as an electron carrier in experimental models.

Common questions
- What purity is NAD+, and how is it tested?
- NAD+ is supplied at 99%+ purity. Each production lot is tested by an independent third-party laboratory, with HPLC for purity and mass spectrometry for identity. Published certificates can be looked up by the lot number printed on your vial in our COA library.
- Does NAD+ come with a Certificate of Analysis?
- Certificates are published online rather than printed in the box. You can view and download the certificate on this page before you buy, and match the lot number on your vial to its certificate in the COA library. Our guide on how to read a peptide COA explains each section.
- How fast does NAD+ ship?
- Orders placed before 2 PM EST ship the same day from the United States, with tracking and discreet packaging.
- How should NAD+ be stored?
- Store at -20°C. Our storage and handling guide covers temperature, light and moisture in more detail.
- What if independent testing doesn't confirm the stated purity?
- Our Purity Guarantee covers it: if independent testing does not confirm the stated purity, you get a full refund and a free replacement.
- Is NAD+ for human use?
- No. NAD+ is sold strictly for laboratory research use only. It is not for human or veterinary use, and we do not provide dosing or administration guidance.
