Key takeaways

NAD existed before life & kickstarted living processes
NAD+ is a universal coenzyme that transfers energy across all cells, keeping you alive & well
Enzymes act like machines while coenzymes (NAD+) serve as the tools they need to work
NAD+ sits at the center of all metabolic processes, regulating glucose, building, & breaking down substances
Mainstream interest in NAD+ surged after Dr. David Sinclair’s book Lifespan hit shelves around 2017
NAD+ levels drop every decade, leading to less energy & slower cellular repair with age
Sun exposure both helps & harms Too much damages DNA & drains NAD+ through increased repair demands
Chronic inflammation & DNA damage reduce NAD+ levels faster, causing energy loss & fatigue
Oral NAD+ precursors boost cellular energy more efficiently than IV NAD+ for daily health with fewer side effects
Good sleep, regular exercise, & healthy habits maintain NAD+ levels, slowing aging & improving performance
