Boosting NAD for Healthy Aging
Aging affects every system in the body, yet its earliest signs begin at the microscopic level . Long before gray hair or joint stiffness appear, subtle changes occur inside our cells. Energy production slows, repair mechanisms weaken, and inflammation becomes harder to control. At the center of these shifts lies a molecule called nicotinamide adenine dinucleotide, or NAD. Scientists now recognize that maintaining healthy NAD levels may play a critical role in promoting longevity and protecting cellular function over time. The Biological Role of NAD in the Human Body NAD is a coenzyme present in all living cells. It enables essential chemical reactions that convert nutrients into usable energy. More specifically, NAD participates in redox reactions that fuel mitochondrial ATP production. Without it, cells cannot efficiently generate energy. However, energy metabolism represents only part of the story. NAD also supports proteins known as sirtuins, which regulate inflammation, stress resi...
