NADH (Reduced Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that is derived from vitamin B-3, also known as niacin. NADH is an essential cofactor for hundreds of biochemical reactions, and is used extensively in the production of cellular energy (ATP). NADH also plays a notable role in the synthesis of neurotransmitters in the brain. Although NADH is normally unstable outside of the body, PANMOL NADH uses a patented process to naturally preserve its effectiveness, thereby delivering stable and bioavailable NADH to the body. Added Ribose improves cellular energy production of ATP via different pathways than NADH, enhancing the overall effectiveness of this formula.
