nicotinamide-adenine dinucleotide (NAD) a coenzyme that is involved in many biochemical oxidation-reduction reactions. The symbols for the oxidized and reduced forms are NAD and NADH. nicotinamide-adenine dinucleotide phosphate (NADP) a coenzyme similar to nicotinamide-adenine dinucleotide but involved in fewer reactions.
For example, " [NAD] activates enzymes called sirtuins, which have many different effects on the body, including decreasing inflammation, and there're some theories that it may help the body" by increasing longevity, says Neil Paulvin, D.O., a physician specializing in functional medicine and integrative sports medicine.
