After 30, your body stops producing the cellular fuel that keeps you energized.
It's called NAD+, and it's like gasoline for your cells.
When you were young, your NAD+ levels were high. You had endless energy, sharp focus, and recovery was instant.
But after 30, your NAD+ crashes by 50%. By 40, it's down 70%.
Imagine trying to drive cross-country on a quarter tank of gas. That's what your cells are doing every day.
