Research context
Nicotinamide adenine dinucleotide is a coenzyme present in every living cell, where it carries electrons through the reactions that produce cellular energy. Its measured decline with age in research models is what put it at the centre of the longevity literature.
That literature spans mitochondrial function, sirtuin activity and DNA repair enzymology, and remains one of the most active areas of cellular research.
Supplied as a laboratory research reagent. No anti-ageing, longevity or health benefit is claimed for any product on this site.
This summary describes published scientific literature only. It is not a claim of effect, benefit or suitability. All products are supplied strictly for laboratory research use and are not for human consumption, therapeutic use, diagnosis or treatment.
