{"product_id":"nad","title":"NAD+","description":"\u003cp\u003eNicotinamide adenine dinucleotide (NAD⁺) is a coenzyme present in all living cells, derived from vitamin B3 (niacin) precursors. It functions as an electron carrier in redox reactions and as a substrate for NAD⁺-consuming enzymes including sirtuins, PARPs, and CD38.\u003c\/p\u003e\n\u003cp\u003eNAD⁺ levels have been observed to decline with age in research models, which has motivated extensive study of NAD⁺ biology in the context of aging, mitochondrial function, DNA repair, and metabolic disease. Research has also examined NAD⁺ precursors such as NMN and NR.\u003c\/p\u003e\n\u003cp\u003eIt is used as a reference cofactor in studies of cellular metabolism and aging biology.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eFor research purposes only.
