{"product_id":"nad","title":"NAD+","description":"\u003cp\u003eNAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme present in every living cell, central to energy metabolism, mitochondrial function, and DNA repair. It shuttles electrons in the reactions that generate cellular ATP and serves as the required substrate for sirtuins and PARP enzymes that govern DNA repair, gene expression, and stress responses. Research shows NAD+ levels decline substantially with age, by up to 50% between young adulthood and middle age, driven in part by rising CD38 activity, contributing to mitochondrial dysfunction and reduced cellular resilience. Studies demonstrate that restoring NAD+ reactivates sirtuin signaling, improves mitochondrial efficiency, and enhances DNA-repair capacity in aged models. Declining NAD+ is closely linked to hallmarks of aging, metabolic decline, and neurodegeneration. As the master cofactor connecting metabolism to longevity pathways, NAD+ is one of the most extensively studied model compounds in aging, mitochondrial, and cellular-energy research.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eFor laboratory and research use only.
