Beta-Alanine, Hydration and Stress, Vitamin D, and more with Dr. Nicholas Barringer | Ep 674

Welcome to the Mind Muscle Connection Podcast!

In today’s episode, I sit down with Dr. Nick Barringer, a former Army Ranger, researcher, and performance dietitian who’s worked with elite military units, firefighters, and law enforcement.

We dive into how something as simple as hydration can change your stress response, why vitamin D is often prescribed in the wrong form, and how supplements like beta‑alanine and creatine support both the body and the brain. Nick also breaks down what he’s seeing in new studies on stress resilience, recovery tools like float tanks, and why firefighters face higher cardiovascular risk than the fires themselves.

This episode is a very interesting and full insight, so be sure to tune in!
