NAD+ 500mg

NAD+ — Nicotinamide Adenine Dinucleotide

NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a pyridine nucleotide coenzyme central to every major energy-producing pathway in the cell. Intracellular NAD+ pools decline measurably with age, a phenomenon that has positioned NAD+ restoration at the center of modern longevity and metabolic research. Unlike precursors such as NR or NMN, NAD+ itself is delivered directly in research protocols for rapid pool expansion.

Mechanism of Action

NAD+ is an obligate cofactor for sirtuin deacetylases (SIRT1–SIRT7), which regulate transcription, DNA repair, mitochondrial biogenesis, and circadian metabolism. It also serves as a substrate for PARP-family enzymes during the DNA damage response and for CD38, a plasma-membrane ectoenzyme whose age-related upregulation contributes to declining NAD+ pools. Restoration of intracellular NAD+ supports activity at all three enzyme classes, with downstream consequences for mitochondrial function, chromatin state, and genomic stability.
