Researchers sourcing NAD+ for preclinical studies need a supplier that understands the analytical characterization of a small molecule coenzyme that is not a peptide but is often studied alongside research peptides in integrated metabolic research programs. NAD+ has specific purity and stability requirements that differ from peptide research products, and research grade supply has to address those requirements. This guide covers supplier evaluation criteria and shows how Midwest Peptide meets those criteria.

Frequently Asked Questions
What is NAD+ in research contexts?
+
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, central to redox metabolism and serving as a substrate for sirtuins, PARP enzymes, and CD38. It is studied in research models for cellular energy, mitochondrial function, DNA repair, and aging biology.
What sourcing standards apply to research NAD+?
+
Verify HPLC purity above 98%, mass spec identity confirming the molecular structure, content quantification, endotoxin testing where applicable, clear documentation of the form (free acid, disodium salt), and stability data. Storage conditions are critical for NAD+ integrity.
Where can research labs source verified NAD+?
+
Midwest Peptide supplies research-grade NAD+ with comprehensive COA documentation, HPLC purity verification, mass spec identity, and lot tracking for reproducible cellular metabolism, mitochondrial, and longevity research.
Is NAD+ approved for human use?
+
No. NAD+ is not approved by the FDA for any human therapeutic use. It is supplied strictly for in-vitro and preclinical research purposes by qualified investigators.
Glossary
Key terms used in this article.
- NAD+/NADH
- The oxidized (NAD+) and reduced (NADH) forms of nicotinamide adenine dinucleotide, central to redox metabolism.
- Sirtuin
- A family of NAD+-dependent deacylase enzymes (SIRT1 to SIRT7) that regulate metabolism, stress response, and aging.
- PARP
- Poly(ADP-ribose) polymerase, a family of NAD+-consuming enzymes critical for DNA damage repair.
- NMN
- Nicotinamide mononucleotide, a direct biosynthetic precursor to NAD+ studied as a supplementation strategy.
- NR
- Nicotinamide riboside, an NAD+ precursor that is converted to NMN by NRK enzymes before incorporation into NAD+.
- Disodium Salt
- A common stable salt form of NAD+ used for research, with two sodium counter-ions.
- Coenzyme
- A non-protein chemical compound that binds to enzymes to support their catalytic activity, of which NAD+ is a primary example.
