NAD+ plays a central role in several critical biological processes:
Energy Production: It is essential for converting the nutrients we eat into ATP (adenosine
triphosphate), which is the primary energy currency used by all our cells.
Cellular Defense and Repair: NAD+ is required for enzymes (like sirtuins and PARPs) to
repair damaged DNA, maintain chromosomal integrity, and regulate inflammation.
Regulating the Aging Process: Natural levels of NAD+ decline significantly as we
age—dropping by roughly half between our 20s and 50s. This decline is linked to physical fatigue, cognitive
decline, and the visible signs of aging.
