Methylene blue is one of the most talked-about tools in biohacking for mitochondrial function, brain fog, and energy—and the nuance is in dosing, quality, and context. In this episode, Dr. Scott Sherr explains how chronic stress and hormone shifts can trap women in a “wired but tired” state, why HRV drops when your nervous system can’t recover, and how sleep architecture, minerals, and mitochondrial support may help restore resilience. You’ll also learn the red flags of low-quality methylene blue, why low-dose and high-dose effects are different, and how to think about redox balance without making your stress physiology worse.
