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 Does NADH Work?).
The best dosage for NADH has not yet been established, since the supplement has not been thoroughly studied
(see NADH Dosage).
There are no known side effects of NADH. However, this probably reflects a lack of clinical studies on the product, not a real absence of side effects
(see NADH Side Effects to learn more, including potentially serious side effects you should report to your healthcare provider.)
At this time, it is not known if NADH interacts with other supplements or medications
(see NADH Drug Interactions).
Some people may be more likely to experience problems with NADH than others. Therefore, you should talk with your healthcare provider before taking it if you have:
- Liver disease, such as liver failure, cirrhosis, or hepatitis
- Kidney disease, such as kidney failure (renal failure)
- Any other serious or chronic health condition
- Any allergies, including allergies to medications, foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
Make sure to tell your healthcare provider about all of the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

What If I Take an Overdose?
It is not known what exactly to expect from an overdose of NADH. If you think you may have taken too much, seek immediate medical attention.
How Should NADH Be Stored?
Refer to the label of your individual NADH product for information on how best to store it. Keep this and all other medications or supplements out of the reach of children.
