NAD+ 1,000mg

Description

Essential coenzyme for energy production and DNA repair research.

NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme present in every living cell, serving as a critical electron carrier in metabolic redox reactions including glycolysis, the citric acid cycle, and oxidative phosphorylation. Beyond energy metabolism, NAD+ functions as a substrate for sirtuins (SIRT1-7), poly(ADP-ribose) polymerases (PARPs) involved in DNA repair, and CD38/CD157 ectoenzymes involved in calcium signaling. NAD+ levels decline significantly with age, and this decline has been implicated as a driver of metabolic dysfunction and cellular senescence. Seminal research by Imai and Guarente (2014) in Trends in Cell Biology established the NAD+ depletion theory of aging, demonstrating that declining NAD+ levels impair sirtuin activity and mitochondrial function. Studies by Yoshino et al. (2011) in Cell Metabolism showed that NAD+ precursor supplementation restored metabolic function in aged and diet-induced obese mice. Research in Science by Li et al. demonstrated that NAD+ repletion improved muscle stem cell function and extended lifespan in aged murine models through SIRT1-dependent mechanisms. This 500mg formulation provides a direct NAD+ supply for research applications. Compared to precursors like NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside), which require enzymatic conversion, direct NAD+ bypasses biosynthetic pathway bottlenecks, though its larger molecular size presents different cellular uptake considerations. Each approach offers distinct advantages depending on the research model. Store lyophilized NAD+ at -20°C, protected from light and moisture, as it is hygroscopic. Reconstitute with bacteriostatic water and store at 2-8°C, using within 2-3 weeks, as NAD+ is susceptible to hydrolytic degradation in solution. NAD+ is studied by aging researchers, metabolic scientists, DNA repair biologists, and mitochondrial function specialists.
