Nicotinamide adenine dinucleotide (NADH) is the active coenzyme form of vitamin B3 (niacin). NADH deficiency is known to occur only in the presence of vitamin B3 deficiency, which is rare in Western society except in some alcoholics.

What it does

NADH plays an essential role in the energy production of every human cell. It is thought that some people may have difficulty converting Vitamin B3 to NADH making them prone to disorders which affect energy levels. There is some NADH in meat, fish and poultry but it is thought that it may not be well absorbed in sufficient quantity.
