Longevity Supplements for Men Over 40: The Complete Protocol
After 40, the strategies that used to work stop delivering. More coffee doesn't fix the fatigue. Recovery takes longer. Mental sharpness requires more effort. This isn't just aging. It's a measurable decline in cellular energy production, mitochondrial efficiency, and cardiovascular function that targeted supplementation can meaningfully address. NMN restores NAD+. PQQ builds new mitochondria. Paraxanthine supports nitric oxide and clean cognitive performance. Betaine protects cardiovascular integrity. This is the complete protocol.
Paraxanthine and Nitric Oxide: Boosting Physical Longevity and Brain Health
Most stimulants narrow blood vessels and work against your vascular system. Paraxanthine does the opposite. By supporting nitric oxide signaling through PDE9 inhibition, it improves blood flow, oxygen delivery, and endurance while protecting dopaminergic neurons over time. Research shows up to a 39% increase in endurance and measurable strength gains. This is clean energy that supports both performance and long-term brain health.
