What Happens to NAD+ Levels as We Age?
NAD+ levels decline by up to 50% by middle age — driven by increased PARP and CD38 consumption, a slowing salvage pathway, and reduced biosynthesis. Learn why this matters for cellular health and what the science says about supporting NAD+ as we age.
Why Is NAD+ Important for Cellular Health?
NAD+ is essential for every major aspect of cellular health — from ATP energy production and DNA repair to sirtuin activation and redox balance. Learn why its decline with age matters and what the science says about supporting it.
Why Does Everyone Over 30 Feel Exhausted — Even After a Full Night's Sleep?
Discover the cellular science behind why people over 30 feel tired even after a full night's sleep — and how NAD+ and NR work together to restore energy at the source.
