NAD+ (Nicotinamide Adenine Dinucleotide) is a naturally occurring coenzyme found in all living cells. It plays an essential role in cellular energy metabolism, mitochondrial function and numerous biochemical reactions involved in maintaining cellular homeostasis.
NAD+ is a central component of oxidation-reduction reactions, acting as an electron carrier during metabolic processes. It participates in glycolysis, the citric acid cycle and oxidative phosphorylation, supporting the biochemical pathways responsible for cellular ATP production.
Beyond energy metabolism, NAD+ serves as a substrate for several important enzyme families, including sirtuins, poly(ADP-ribose) polymerases (PARPs) and CD38. These enzymes are involved in cellular stress responses, DNA repair, metabolic regulation and intracellular signaling.
Scientific research has investigated the relationship between NAD+ availability, mitochondrial function and biological aging. Experimental studies have observed changes in NAD+ metabolism in certain tissues and physiological conditions, generating interest in its potential relationship with age-associated cellular dysfunction.
NAD+ 500 mg is presented as an experimental research compound for laboratory and scientific applications. The stated quantity refers to the amount of NAD+ contained in the product and should not be interpreted as a recommended human dosage.
