NAD+ in published research

Verdin's 2015 Science review (PMID 28066005) and Rajman et al.'s 2018 Cell Metabolism paper (PMID 30693472) provide useful entry points into NAD+ metabolism research. Both publications describe NAD+'s role in mitochondrial-function and sirtuin-pathway research models.

NAD+ vs. NMN vs. NR research compounds

NMN and NR are NAD+ precursors studied for their conversion pathways. Research literature suggests divergent uptake mechanisms across cell types — researchers selecting between the three compounds should refer to the cited literature on the product page.

Vial sizes

Available in lyophilized 100 mg, 500 mg, and 1 g vials.

Research FAQ — NAD+

Frequently asked questions about this compound for laboratory researchers.

What is NAD+ in a research context?+
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to redox biology and sirtuin-pathway research. Published literature investigates NAD+ metabolism in aging, mitochondrial function, and metabolic-disease models.
How is NAD+ different from NMN and NR research compounds?+
NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are NAD+ precursors studied for their conversion pathways and bioavailability profiles. Research suggests divergent uptake mechanisms across cell types.
How is NAD+ stored in a research setting?+
Lyophilized NAD+ stores at −20 °C protected from light. Reconstituted solution is held at 2–8 °C and used within 30 days. Refer to product COA.
Is NAD+ third-party tested?+
Every NAD+ lot shipped by BioInfinity is HPLC-tested by Janoshik Analytical with a Certificate of Analysis referenced on the product page.
