NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and one of the most abundant molecules in biology, documented to take part in over 500 enzymatic reactions. In redox research it is the electron carrier that cycles between NAD+ and NADH, carrying high-energy electrons to the mitochondrial electron transport chain, the machinery cells use to synthesise ATP. It is a molecule with a century of pedigree, first identified in 1906 and tied to the 1929 Nobel Prize in Chemistry. Laboratory studies have observed that NAD+ levels decline with age across multiple tissues, which is the finding that made it a flashpoint in longevity and mitochondrial research.
