NADH (nicotinamide adenine dinucleotide hydrate) is a naturally occurring molecule found throughout the human body. It is not considered a vitamin, since the body can make its own NADH. It is also used as an ingredient in
dietary supplements and has been claimed to help with the following conditions:
These are just some of the reported uses. NADH is often promoted as a supplement for general health and nutritional enhancement.
NADH is a molecule that works as a coenzyme in the human body. Coenzymes help other enzymes work in chemical reactions. Many essential chemical reactions in the body use NADH. It is not known exactly how supplementation could work for various conditions, especially since the body can make its own. NADH may have antioxidant activity, and this may be one way that it works for various conditions.
At this time, there is not enough scientific evidence available to suggest that NADH is truly effective for any use
(see
