Nicotinamide Adenine Dinucleotide (NAD) is a coenzyme found in all living cells. The compound is a dinucleotide, because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base and the other nicotinamide. 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 stands for “nicotinamide adenine dinucleotide (NAD) + hydrogen (H).” This chemical occurs naturally in the body and plays a role in the chemical process that generates energy.
NADH is a coenzyme, and is an activated form of the B vitamin niacin. It’s present in all living cells. As a coenzyme, NADH serves an important role in helping enzymes to function as they should. (An enzyme is a protein that works like a catalyst in the body to prompt chemical changes in other substances; breaking down food into energy is an example.) Most coenzymes are synthesized from vitamins, and for optimal energy production, the body needs good amounts of them. The coenzyme, NADH, is no exception.
NADH is used for improving mental clarity, alertness, concentration, and memory. NADH is also used for improving athletic endurance and treating fatigue.
Some people use NADH for treating high blood pressure, high cholesterol, jet lag, depression; boosting the immune system; mitigating alcohol’s effects on the liver; and reducing signs of aging.
