NAD+ is a crucial coenzyme involved in cellular energy production, DNA repair, and metabolic regulation. It serves as a co-substrate for sirtuins and PARPs, supports mitochondrial function, regulates circadian rhythms, enhances cellular antioxidant defenses, and declines naturally with age. Supplementation with precursors (NR, NMN) restores NAD+ levels.
