The Full Form of NADH is‍ Nicotinamide Adenine Dinucleotide – Hydrogen.

Nicotinamide adenine dinucleotide exists in two forms, an oxidized and reduced form abbreviated as NAD+ and NADH respectively.

NAD+ is found in every cell in the body and is essential to life. NAD+ enables the transfer of energy from the foods we eat to vital cell functions. It is also required to “turn off” genes that accelerate degenerative aging processes.

NADH (the reduced form of NAD+) is a coenzyme and is an activated form of the B vitamin niacin. It is present in all living cells. As a coenzyme, NADH plays a role in numerous biological reactions in the body including the generation of cellular energy as well as the synthesis of neurotransmitters in the brain.
