NAD is a chemical that functions as a coenzyme in all living cells. In its oxidised state, NAD+, this molecule aids cells in converting nutrients into energy while also supporting proteins that govern a variety of cellular processes.
NAD+ is now known to play a function in everything from metabolism to DNA repair and even the maintenance of the circadian rhythm.
While the NAD+ coenzyme is essential for cellular activity, it is depleted in many organisms, including humans, throughout time. As a result, decreased NAD+ levels are linked to age-related disorders such as cancer, cognitive decline, diabetes, arthritis, hypertension, and atherosclerosis. NAD+ level regulation can promote metabolic balance for a longer life span.
