NADH (Reduced Nicotinamide Adenine Dinucleotide) is the metabolically active form of Vitamin B-3, also known as Niacin. NADH is essential for the production of cellular energy (ATP) from glucose and fat. Therefore, the more NADH a cell has available, the more energy it has available to operate with efficiency. NADH is also directly involved in neurotransmitter production, the maintenance of genetic integrity and the support of healthy immunity. Although NADH is normally unstable outside of the body, PANMOL-NADH, found in this NOW NADH supplement, uses a patented process to naturally preserve its effectiveness, thereby delivering stable and bioavailable NADH to the body.
