NAD+
Buy 1, get 1 50% off — optional add-on, you choose whether to include it.
NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme present in every living cell and a central redox carrier in the reactions that generate ATP. It is the required substrate for sirtuin deacetylases and PARP enzymes, which govern DNA repair, chromatin regulation, and cellular stress responses. In-vitro and animal-model research examines the age-associated decline in NAD+ pools, the role of CD38 activity in that decline, and the effects of NAD+ restoration on sirtuin signaling, mitochondrial efficiency, and DNA-repair capacity. As the cofactor linking energy metabolism to longevity-associated pathways, NAD+ is one of the most extensively studied compounds in cellular-senescence, mitochondrial, and neurodegeneration research. NAD+ is supplied as a lyophilized reference compound for redox-biology and cellular-energy research.
For laboratory and in-vitro research use only. Not for human or veterinary use.
