Strong By Design Podcast Ep 425 Creatine for the Brain: Separating Fact from Fiction ft. Dr. Boz [Part 1]
Is your body already producing creatine… and could you still be running low where it matters most—your brain?
In Part 1 of this 2-part series, Coach Chris Wilson sits down with Dr. Annette “Dr. Boz” Bosworth to challenge everything you thought you knew about creatine. While often seen as a muscle-building supplement, this conversation shifts the focus to brain energy, cognitive function, and daily performance.
They break down creatine’s role in regenerating ATP—the fuel that powers every cell, especially in the brain. If you struggle with mid-afternoon crashes, brain fog, or mental fatigue, this episode uncovers what may really be happening.
Chris and Dr. Boz also explore why natural creatine production may fall short, how muscles can compete with the brain for supply, and what happens when intake goes beyond traditional dosing.
You’ll also learn how brain energy connects to sleep, recovery, and long-term cognitive health, including the impact of modern habits and metabolic factors like insulin.
This episode reframes creatine as more than a workout supplement—it’s a foundational tool for brain energy and resilience.
Be sure to tune in to Part 2, where Chris and Dr. Boz dive deeper into cognitive health and creatine myths.
