Introduction
NAD+ (nicotinamide adenine dinucleotide) is one of the most studied molecules in modern longevity and metabolic research. As the obligate cofactor for sirtuins, PARPs, and CD38, NAD+ sits at the intersection of energy metabolism, DNA repair, and gene expression regulation.
Forms of NAD+ Available for Research
NAD+ (oxidized form): The biologically active form used as a direct sirtuin and PARP substrate — the most commonly used form in cellular and molecular research. NADH (reduced form): Used in studies of mitochondrial electron transport and cellular redox state. NAD+ precursors (NMN, NR): Biosynthetic precursors, not NAD+ itself. See our NAD+ precursors comparison for details.
Purity and Documentation Requirements
Research-grade NAD+ should meet: Purity ≥98% by HPLC; identity confirmed by mass spectrometry (MW: 663.43 Da); moisture content <5% for lyophilized preparations; and an independent COA from an accredited third-party laboratory.
Storage Considerations
NAD+ is hygroscopic and sensitive to heat, light, and moisture. Lyophilized NAD+ should be stored at -20°C in a desiccated environment. Once reconstituted, solutions should be used promptly or stored at -80°C in aliquots to prevent oxidation.
Pure Pharm Peptides NAD+
Pure Pharm Peptides supplies NAD+ in 500mg and 1000mg vials (10 vials per kit) with independent USA laboratory COA verification at ≥98% purity. View the NAD+ product page for current batch documentation and specifications.
