NAD+ — Nicotinamide Adenine Dinucleotide

Lyophilized NAD+ (Nicotinamide Adenine Dinucleotide), 500mg per vial, HPLC-verified to greater than 99% purity. This compound is a coenzyme found in all living cells, playing a central role in redox reactions and serving as a substrate for several enzyme families involved in cellular regulation.

In laboratory research, it is commonly studied for its role in cellular energy metabolism, particularly its function within the electron transport chain and mitochondrial ATP production pathways. Researchers investigating cellular aging and mitochondrial function examine these levels as a marker of metabolic health in cell culture and animal models, since the coenzyme’s concentrations have been observed to decline with age in various tissue studies. NAD+ also serves as a substrate for sirtuins and PARP enzymes, both of which are studied extensively in DNA repair and cellular stress response research.

Each vial is supplied in lyophilized (freeze-dried) powder form to maintain compound stability during shipping and storage. Once reconstituted with an appropriate diluent, solutions should be stored refrigerated, protected from light, and used within the timeframe recommended by your laboratory’s standard protocols. See our Reconstitution Guide for detailed handling instructions.
