NAD+
Also known as: Nicotinamide adenine dinucleotide · NAD
Nicotinamide adenine dinucleotide — a coenzyme central to mitochondrial energy and sirtuin activity, declining with age.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell, essential to the reactions that turn nutrients into usable energy and to the activity of sirtuins and DNA-repair enzymes. It is not a peptide but a metabolic cofactor.
NAD+ levels fall with age, which is why raising or maintaining the NAD+ pool is a central theme of longevity and cellular-energy research. It is studied directly and via precursors such as NMN.
