Nicotinamide adenine dinucleotide, or NADH, is a coenzyme made from niacin. As a coenzyme, NADH serves an important role in helping enzymes to function as they should.
Until recently, NADH could only be given intravenously because stomach acid would rapidly destroy the delicate molecule.
But a new enteric-coated, oral tablet containing NADH is now available.
Health Benefits Oral NADH supplementation has been used to combat simple fatigue as well as such mysterious and energy-sapping disorders as chronic fatigue syndrome and fibromyalgia.
Researchers are also studying the value of NADH supplements for improving mental function in people with Alzheimer's disease, and minimizing physical disability and relieving depression in people with Parkinson's disease.
Some healthy individuals also take NADH supplements orally to improve concentration and memory capacity, as well as to increase athletic endurance.
