NAD+
Nicotinamide adenine dinucleotide coenzyme · cellular research materials
NAD+ (nicotinamide adenine dinucleotide) is a naturally occurring pyridine-nucleotide coenzyme central to cellular redox reactions. It is a small-molecule cofactor — not a peptide — supplied as a lyophilized powder for laboratory use.
Research context
In published literature, NAD+ is studied in the context of cellular-energy metabolism, redox-balance, and sirtuin-pathway research using in-vitro and preclinical models. Glow Peptides supplies NAD+ strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.
Handling & storage
NAD+ is supplied lyophilized (freeze-dried). General laboratory handling practice for research materials of this type:
- Sealed vials: store lyophilized powder cold and away from light; long-term storage is typically in a freezer. Sealed, dry vials are stable far longer than reconstituted material.
- Reconstitution: research protocols typically reconstitute with bacteriostatic or sterile water introduced slowly against the vial wall, swirled (not shaken) until dissolved. See our reconstitution & storage guide.
- After reconstitution: keep refrigerated and protected from light; material in solution is less stable than the dry powder.
- Documentation: record the lot number and its Certificate of Analysis for your records.
Quality & testing
Every lot of NAD+ we supply is independently tested at a U.S. laboratory and ships with a lot-specific Certificate of Analysis. Testing includes HPLC with UV detection for purity and mass spectrometry for identity, with our purity standard at ≥99%.
You can search any lot and view its documentation on our Quality & COA verification page, and learn what the numbers mean in how to read a Certificate of Analysis. Our published customer rating is 4.5 on Trustpilot.
NAD+ is available as an independently tested, ≥99%-purity research reference material with a per-lot Certificate of Analysis.

Is NAD+ intended for human use?
No. NAD+ is supplied strictly as a reference material for in-vitro laboratory and preclinical research. It is not a drug or supplement and is not for human or veterinary use.
How is NAD+ tested for purity?
Each lot is independently tested at a U.S. laboratory by HPLC with UV detection (purity) and mass spectrometry (identity), and ships with a lot-specific Certificate of Analysis. Our purity standard is ≥99%.
How should NAD+ be stored?
Sealed lyophilized vials are stored cold and away from light, typically frozen for long-term storage. Once reconstituted for research, material is kept refrigerated and protected from light.
