What's Really Behind the Drop in Energy and Performance After 40
Every day, invisible compounds called reactive oxygen species quietly rob you of energy, circulation, and performance.
Three things drive it, and you can't undo them on your own:
- Age: After 40, NAD+ production drops by up to half. Less NAD+ = less energy and weaker circulation. Stress, poor sleep, and lifestyle speed up the NAD+ drop and choke nitric oxide production.
- Lifestyle and stress: Stress, a poor diet, and no exercise damage the endothelium, the lining that controls blood flow and your body's natural response.
- Years of neglect: The longer you wait, the deeper circulation and performance sink, even though your "labs are normal". That's why so many guys over 40 still fight weak erections, no morning wood, and fatigue.
