NAD+ 500mg Vial

NAD+ 500mg in a single research vial — the coenzyme central to cellular energy, DNA repair and sirtuin/longevity research. Reconstitute with bacteriostatic water and dose subcutaneously; injectable delivery bypasses NAD+ poor oral absorption. Third-party tested, 99% purity.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell and one of the most fundamental molecules in metabolism — it shuttles electrons in mitochondrial respiration to produce cellular energy (ATP), is a required substrate for PARP DNA-repair enzymes, and fuels the sirtuin (SIRT1-7) family central to longevity research. NAD+ levels fall substantially with age (roughly halving from young adulthood), a decline linked in research to reduced mitochondrial function, slower DNA repair and lower sirtuin activity. Because the molecule is large, unstable and survives oral absorption poorly, injectable delivery is used to bypass that degradation. This 500mg vial is supplied as research-grade NAD+ for reconstitution with bacteriostatic water and subcutaneous (SubQ) research use — inject slowly, as buffered NAD+ reduces site stinging. Supplied for research use only. 99% purity, third-party tested by Janoshik Analytical.
