The Glucose Protocol: How Fueling Your Brain Restores Clarity with Dr. David Stephens

In this episode Andrea Samadi welcomes back Dr. David Stephens to explore his new book, The Glucose Protocol, and the science showing how targeted glucose can restore brain function, improve mental clarity, and reduce symptoms linked to diabetes, autoimmune disorders, and chronic stress. They break down the difference between glucose and other sweeteners, explain why the brain prioritizes survival over higher-order thinking during stress, and share practical strategies—like on-the-spot glucose dosing—to regain focus and cognitive performance. Dr. Stephens also discusses biomarkers, clinical observations, and upcoming practical products to make brain refueling easy, offering hopeful, science-based approaches to restore long-term brain health.

Welcome back to Season 15 of the Neuroscience Meets Social and Emotional Learning Podcast. I’m Andrea Samadi, and here we bridge the science behind social and emotional learning, emotional intelligence, and practical neuroscience—so we can create measurable improvements in well-being, achievement, productivity, and results. When we launched this podcast seven years ago, it was driven by a question I had never been taught to ask—not in school,not in business,and not in life: If results matter—and they matter now more than ever—how exactly are we using our brain to make these results happen? Most of us were taught what to do.Very few of us were taught how to think under pressure,how to regulate emotion,how to sustain motivation,or even how to produce consistent results without burning out. That question led me into a deep exploration of the mind–brain–results connection—and how neuroscience applies to everyday decisions, conversations, and performance. That’s why this podcast exists. Each week, we bring you leading experts to break down complex science and translate it into practical strategies that we can all apply immediately. When the brain, body, and emotions are aligned, performance stops feeling forced—and starts to feel sustainable. Season 14 showed us what alignment looks like in real life. We looked at goals and mental direction, rewiring the brain, future-ready learning and leadership, self-leadership, which ALL led us to inner alignment. And now, Season 15 is about understanding how that alignment is built—so we can build it ourselves, using predictable, science-backed principles. Because alignment doesn’t happen all at once.It happens by using a sequence. And when we understand the order of that sequence —we can replicate it. By repeating this sequence over and over again, until magically (or predictably) we notice our results have changed. Season 15 we’ve organized as a review roadmap, where each episode explores one foundational brain system—and each phase builds on the one before it. Rather than focusing on outcomes, hacks, or motivation alone, we examine the core brain systems that must be stable before learning, performance, and leadership can emerge. Episodes are organized around a simple but powerful progression: Phase 1: Regulation & Safety — the nervous system foundation for learning Phase 2: Neurochemistry and Motivation—dopamine balance + Emotional regulation Phase 3: Cognition & Learning — attention, memory, and executive function Phase 4: Perception & Social Intelligence — how we read ourselves and others Phase 5: Integration & Meaning — how experience becomes insight and growth Each system builds upon the one beneath it, reminding us that when foundations are ignored, progress is temporary. When they are strengthened, performance becomes sustai
