NAD and Sirtuins

NAD plays a crucial role as a cofactor for electron transport and as a substrate for DNA repair through sirtuins. With age-related declines in NAD levels, enhancing its availability could potentially aid in combating aging. Resveratrol, a well-known sirtuin activator found in grape skins, gained fame for its purported ability to extend lifespan by improving mitochondrial function and enhancing DNA repair mechanisms.
