NAD+ (Nicotinamide Adenine Dinucleotide) is a pyridine nucleotide essential for electron transport, cellular redox reactions, and as a co-substrate for sirtuins (SIRT1-SIRT7), PARPs, and CD38. Intracellular NAD+ pools decline with age, making NAD+ a central molecule in metabolism and aging research.

NAD+ is used in sirtuin-activity assays, mitochondrial-bioenergetics research, aging models, and redox-state profiling where the NAD+/NADH ratio is a central readout.
