NADH, short for nicotinamide adenine dinucleotide, is an important pyridine nucleotide that functions as an oxidative cofactor in eukaryotic cells.NADH plays a key role in the production of energy through redox reactions.icotinamide adenine dinucleotide (NAD) is one of the most important coenzymes in the cell. Not surprisingly, NAD and the closely related NADP are the two most abundant cofactors in eukaryotic cell.
Normal aging is accompanied by a noticeable increase in fatigue and loss of motivation. The tiredness we outwardly feel reflects inward impairment of cellular functions critical to sustaining life. NAD+ is the term used in the scientific literature to describe a cellular compound called nicotinamide adenine dinucleotide. NAD+ is found in every cell in the body and is essential to life.1,2 NAD+ enables the transfer of energy from the foods we eat to vital cell functions. It is also required to âturn offâ genes that accelerate degenerative aging processes.3,4.
