Episode 377: Methylene Blue for Mitochondria & Performance: Benefits, Dosing & Risks with Dr. Scott Sherr

In this episode of the Flex Diet Podcast, I sit down with Dr. Scott Sherr to take a deep dive into methylene blue, mitochondrial function, and where the truth lies between online hype and fear. We talk through how methylene blue acts as a redox cycler in the mitochondria, how dosing differs for mitochondrial support versus antimicrobial use, and why high doses or poorly labeled liquid droppers can cause problems.  Dr. Sherr also shares how he’s used methylene blue with athletes for recovery and endurance, including timing, half-life, and practical ranges he sees most often. We cover how mitochondrial health connects to energy, mood, focus, stress physiology, and recovery, plus resources from Transcriptions and the Health Optimization Medicine and Practice (HOMe/HOPe) framework.
