Mitochondrial and Energy Production
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. People use NADH supplements as medicine.
NADH is used for improving mental clarity, alertness, concentration, and memory; as well as for treating Alzheimer's disease. Because of its role in energy production, NADH is also used for improving athletic endurance and treating chronic fatigue syndrome (CFS).
Some people use NADH for treating high blood pressure, high cholesterol, jet lag, depression, and Parkinson's disease; boosting the immune system; opposing alcohol's effects on the liver and the hormone testosterone; reducing signs of aging, and protecting against the side effects of an AIDS drug called zidovudine (AZT).
