NAD+

NAD+ (Nicotinamide Adenine Dinucleotide) is an endogenous nucleotide coenzyme essential for metabolism, energy production, and DNA repair. It serves as a substrate for sirtuins (SIRTs), poly ADP ribose polymerases (PARPs), and cyclic ADP ribose synthetases (cADPRS). Research indicates applications in aging, neurodegeneration, DNA repair, organ protection, and cardiovascular function.
