NAD+ Research Compound
Lyophilized Format • ≥99% HPLC Purity • Ships in 1–2 Business Days • U.S. Warehouses
NAD+ (Nicotinamide Adenine Dinucleotide, beta-NAD) is an endogenous dinucleotide coenzyme found in all living cells, supplied by Nextday Peptides for laboratory and analytical research applications. First discovered in 1906 by Harden and Young during investigations into yeast fermentation, NAD+ has since become one of the most extensively studied coenzymes in cellular biology. Each vial is independently verified to ≥99% HPLC purity with a Certificate of Analysis available on request. For scientific research use only.

Why Research Laboratories Select NAD+
NAD+ is one of the most fundamental and extensively studied coenzymes in biological research. As a central mediator of redox reactions — alternating between its oxidized (NAD+) and reduced (NADH) forms — it participates in over 500 enzymatic reactions and serves as an essential reference compound for laboratories investigating cellular energy metabolism, sirtuin biology, DNA repair pathways, and redox signaling.
- Essential dinucleotide coenzyme — mediates electron transfer in cellular metabolic pathways
- Substrate for sirtuin enzymes (SIRT1-7) studied in the context of gene regulation and cellular stress response
- Substrate for PARP enzymes studied in DNA repair pathway research
- Studied as an extracellular signaling molecule in neuronal and vascular biology research models
- Central to glycolysis, citric acid cycle, and electron transport chain research models
- Referenced in hundreds of peer-reviewed publications across cellular and molecular biology
- Batch and lot identifiers on all labeling for full laboratory documentation compliance
Research Background
NAD+ was first identified in 1906 and has been the subject of continuous scientific investigation for over a century. Modern research has examined its role as a substrate for sirtuin deacetylases, PARP enzymes, and CD38, as well as its involvement in mitochondrial function and cellular redox homeostasis. Preclinical studies in rodent models have investigated NAD+ precursor supplementation and its effects on metabolic parameters.

Frequently Asked Questions
What is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is an endogenous dinucleotide coenzyme found in all living cells. It mediates electron transfer in cellular metabolic pathways and serves as a substrate for sirtuin and PARP enzymes. It is supplied strictly for scientific, analytical, and in-vitro laboratory research use only.
How does NAD+ differ from NMN and NR?
NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are NAD+ precursors — compounds that can be converted to NAD+ through cellular metabolic pathways. NAD+ is the active coenzyme form itself. All three are distinct compounds studied separately in laboratory research settings.
What purity is your NAD+?
Every batch is independently verified to ≥99% HPLC purity. A Certificate of Analysis is available for each lot.
