Have you ever heard of inositol? Could you be deficient and not even realize it? If you’re struggling with blood sugar swings, irregular cycles, anxiety, or 2am wake-ups, could this overlooked compound be a missing piece? While magnesium, B vitamins, and electrolytes dominate most wellness conversations, myo-inositol plays a critical role in insulin signaling, ovarian function, and neurotransmitter balance, acting as an intracellular messenger that helps your cells properly respond to hormonal cues.

This episode unpacks what myo-inositol actually is, how it functions in the body, and what the research shows in areas like PCOS, insulin resistance, fertility, mood disorders, and sleep. It also covers therapeutic dosing, food sources, and how to use supplementation strategically for clinical outcomes. Whether you’re navigating hormone imbalance, metabolic dysfunction, or nervous system dysregulation, this conversation takes a deeper look at why myo-inositol deserves far more attention in root-cause medicine.
