Introduction

Creatine is best known as a sports supplement for enhancing muscle strength and high-intensity performance. But could it also improve brain health and cognitive function? Or are such claims overhyped?

If creatine can support brain health, it could have implications for aging, neurodegenerative diseases, concussion recovery, and mental fatigue.

In this podcast episode, Professor Eric Rawson discusses what current science says about creatine’s effects on the brain, including memory, executive function, and protection against neurological stress.

Professor Rawson provides context on how creatine works in the body, why the brain might benefit, and what evidence exists so far.
