A critical coenzyme in cellular energy metabolism, DNA repair, and sirtuin activation; widely studied in longevity, aging, and mitochondrial function research.
Nicotinamide adenine dinucleotide (NAD⁺) is a dinucleotide found in all living cells and a central player in hundreds of metabolic reactions. It functions as a hydride transfer agent in the electron transport chain and as a substrate for sirtuins (SIRT1–7) and PARP proteins — enzymes whose activity is directly dependent on NAD⁺ availability.
Declining NAD⁺ levels with aging have become a major focus of longevity research. Studies in animal models link NAD⁺ repletion with improved mitochondrial function, enhanced DNA damage repair, reduced inflammatory signaling, and extended healthspan. Research groups examine NAD⁺ in the context of its biosynthetic precursors (NMN, NR) and the enzymatic pathways through which intracellular NAD⁺ is maintained and regulated.
At 500mg per vial, this preparation is suitable for cell culture experiments, biochemical assays, enzyme kinetics studies, and metabolic research protocols. NAD⁺ is water-soluble and hygroscopic — proper lyophilized storage is essential to maintain integrity prior to reconstitution.
