About NAD+
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme central to cellular redox reactions and energy metabolism. In research it is studied for its role in mitochondrial function, sirtuin signaling, DNA repair pathways, and aging-related endpoints.
NAD+ is sold worldwide as a research-use-only (RUO) compound, typically as a lyophilized powder. Purity and consistency vary between suppliers, which is why third-party lab testing (HPLC, mass spectrometry) and certificates of analysis matter when comparing options.
NAD+ Suppliers
Suppliers below surface lab data, COAs, and shipping details so you can compare with more context.
What to look for
When comparing NAD+ suppliers, the most useful transparency signals are:
- Third-party COAs — independent HPLC and mass spectrometry results from a recognised lab (Janoshik, Chromate, etc.)
- Batch consistency — multiple recent COAs across different batches, not a single static document
- Endotoxin & heavy metals — additional safety testing for research use
- Vial size — NAD+ is typically supplied in 100mg–500mg vials; check what suits your protocol
- Shipping clarity — published transit times to your country, with tracking
Frequently Asked Questions
What is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell, central to redox reactions and energy metabolism. In research it is studied for its role in mitochondrial function, sirtuin signaling, DNA repair, and aging-related pathways.
Where can I buy NAD+?
NAD+ is sold by multiple research suppliers worldwide. The suppliers above ship to the United States, Europe, the UK, and other regions, with available lab data and transparency signals.
What should I look for in a NAD+ supplier?
Look for third-party COAs (HPLC and mass spectrometry), endotoxin and heavy-metals testing, transparent batch documentation, and consistent community reviews. All suppliers above surface this data.
How is NAD+ different from NMN or NR?
NAD+ is the active coenzyme itself. NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are precursors the body converts into NAD+. Research peptide suppliers typically sell the lyophilized NAD+ form for laboratory study.
