It has been demonstrated that increasing intracellular NAD levels has a notorious anti aging effect. And this is something simple to understand because NAD is required for all fundamental life processes, the most important of them being the creation of energy from nutrients.
With more energy available, the essential cell activity in all our bodies becomes revitalized, optimizing cellular function.
Some people are born with a genetic predisposition to low intracellular levels of NAD, but in most people NAD decreases with age.
Consequently by increasing NAD cellular concentrations our cells behave with youthful vitality. Our brain, our heart, our skin, every single tissue and organ becomes rejuvenated.
