1. Your cells run on NAD+
NAD+ converts what you eat into ATP, the fuel every cell in your body actually uses. Less NAD+ means less output, no matter how well you eat or sleep
2. Your DNA repair depends on NAD+
The enzymes that find and fix cellular damage consume NAD+ to do their work. When it runs short, repair slows and damage accumulates
3. NAD+ levels fall as you age
Human tissue studies have measured lower NAD+ in older adults, in skin and in skeletal muscle. Those are the years when people start noticing fatigue, slower recovery and mental fog
Most people don't lose their health in one moment. They lose it in increments small enough to explain away, until the life they're living isn't the one they'd have chosen.
