NAD+ (nicotinamide adenine dinucleotide) is a foundational coenzyme research compound central to cellular energy, redox balance, and repair. It is studied as an essential substrate for the sirtuin, PARP, and CD38 enzyme families, and for its role in mitochondrial function and the DNA-repair pathways tied to cellular aging—processes whose decline is linked to age-related cellular dysfunction. Supplied for laboratory investigation, NAD+ offers researchers a window into the metabolic and longevity-related mechanisms that underpin cellular vitality.
