Listen to This Before You Buy Another Supplement

You’re drinking more coffee. Taking more supplements. Sleeping longer when you can.

Yet your energy still crashes. Your focus disappears. Your recovery feels slower. And your nervous system feels permanently switched on.

In this episode of the Optimising Human Performance Podcast, human performance scientist Phil Learney unpacks why so many ambitious people feel exhausted despite investing heavily in their health, productivity, and performance.

Phil explains how modern lifestyles create chronic nervous system overload, why recovery has become one of the biggest missing links in performance, and how sleep influences everything from cognitive function and metabolism to emotional regulation and resilience.

The conversation also explores caffeine dependence, overstimulation, supplement quality, stress regulation, behavioural habits, and why sustainable performance starts with understanding capacity.

If you want more energy, better recovery, clearer thinking, and performance that lasts, this episode delivers a practical framework for understanding what actually moves the needle.
