Functional Medicine Reality Podcast
The Functional Medicine Reality Podcast exposes the truth about what really happens in healthcare and why so many patients with complex, chronic conditions are left searching for answers. Hosted by Dr. Mark Su, founder & leader of RootSeek’s nationwide virtual care team, this show goes beyond quick fixes to uncover the root causes of illness—like Lyme disease and co-infections, mold toxicity, gut dysbiosis, hormone imbalances, hidden infections, and heavy metal exposure.
Each episode reveals real patient journeys and expert clinician reasoning, showing you how functional medicine tackles chronic fatigue, autoimmune flares, brain fog, cardiovascular risk, and hard-to-solve cases where conventional medicine often stops short. From environmental toxins to stress-driven inflammation, from gut repair to longevity hacks, you’ll learn how to advocate, decide, and heal on your terms—with practical, next-step strategies you can trust. If you’ve ever wondered how to navigate “mystery symptoms,” controversial treatments, or cutting-edge testing, this podcast will be your compass.
Episode highlights:
- Goes “behind the curtain.” We invite clinicians to think out loud, showing the decision-making process most patients never see.
- Spotlights real patient journeys. Raw stories reveal the triumphs and trade-offs of navigating chronic illness, performance optimization, preventive care, and more.
- Asks the hard, patient-centered questions. We challenge experts on controversies, practical constraints, and emerging evidence—so you can separate trustworthy insight from trend-driven noise.
- Delivers actionable clarity. Whether you’re rehabbing an injury, hacking longevity, or just trying to sleep better, you’ll leave with next-step strategies backed by clinical reasoning.
The team at RootSeek (nationwide virtual care) is ready to empower you to advocate, decide, and heal, on your terms!
