NAD+ 500mg

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, where it plays a central role in energy metabolism and cellular function. It participates in the transfer of electrons during the reactions that convert nutrients into usable energy, and serves as a substrate for enzymes involved in DNA repair and cellular signaling. Research indicates that NAD+ levels decline with age, and studies have examined its involvement in mitochondrial function, oxidative stress response, and the activity of longevity-associated proteins such as sirtuins. It remains a widely studied compound in research focused on cellular energy, metabolism, and the biology of aging.
