About this listen

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!

If you’re asking any of the following questions (or something similar), this podcast is for you:

  • Can functional medicine help with chronic Lyme disease, co-infections, or post-treatment symptoms?
  • How do I know if mold toxicity or environmental toxins are making me sick?
  • What’s the best way to detox from heavy metals, pesticides, or hidden chemical exposures?
  • Are my fatigue, brain fog, or joint pains linked to gut health or hidden infections?
  • How do functional medicine doctors diagnose and treat autoimmune conditions differently?

  • 07. Understanding Mold: Myths, Realities, and Treatment Options
    Jan 25 2026

    Alright, so here's one I get asked constantly: Do I really need to throw out all my belongings if there's mold in my house?

    If that question's been keeping you up at night, or if you're stuck wondering whether dealing with mold means going bankrupt and starting over, take a deep breath. This episode's for you.

    I brought back Mike Schrantz, one of the most networked indoor environmental professionals in the country. He's what I call a "doctor of houses and buildings." And we got into the real, practical reality of what mold remediation actually looks like. Not the fear-based stuff you find all over social media. The truth.

    Here's what we talked about:

    What to actually expect from a mold inspection and report. Mike breaks down why "normal" looks different depending on where you live, and how outdoor mold is different from indoor sources.

    The four categories of remediation: surface cleaning, air quality, contents (furniture, clothing, papers), and deeper structural issues. Not everything requires ripping down walls.

    Why the contents question brings up the most emotion. This is where people panic about throwing everything away. Mike explains what "clean enough" actually means and why treating mold like plutonium creates unnecessary fear.

    The truth about mycotoxins. They have short half-lives. Normal laundering removes them from fabrics. You can clean furniture without throwing it away. And no, you probably don't need to get rid of everything.

    Why the fear itself might be doing more harm than the actual exposure. We talk about the emotional toll, the financial strain, and why so many people end up spending tens of thousands on things they didn't need to do.

    Bottom line: Most situations don't require moving out or going bankrupt. There are sequential steps you can take. And clarity itself can be medicine.

    If you're dealing with mold concerns, chronic illness, or wondering if your environment is making you sick, this conversation will help you move forward with less overwhelm and more confidence.

  • 06. Understanding Your Symptoms: The Critical Role of Differential Diagnosis
    Jan 18 2026

    Hey friends, this one's for both practitioners and patients who've been around the functional medicine world for a while.

    Here's the thing. When you've been dealing with chronic symptoms for months or years, it's really easy to fall into patterns. You start assuming every flare-up is the same old story. SIBO acting up again. Mold toxicity. Food sensitivities.

    But what if it's not?

    I'm talking about the differential diagnostic list, which is just a fancy way of saying: all the possible things that could be causing your symptoms. And here's where it gets tricky for those of us working in the functional medicine world.

    We get so focused on the chronic inflammatory stuff, the SIBO, the parasites, the mycotoxins, that sometimes we can overlook the conventional diagnoses. The diverticulitis. The cancer, God forbid. The kidney stones. The things that need attention now.

    I'll be honest, this is something I actively remind myself about. When I'm seeing a patient I've worked with for two years, and they come in describing abdominal pain, it's tempting to just pick up where we left off. But if they tell me the pain is different somehow, more intense, or now there's bleeding when there wasn't before, I cannot just chalk that up to hemorrhoids and move on.

    Now, if you're a patient, here's what I want you to hear. Pay attention when symptoms vary, even just a little bit. Maybe they're 20% more intense. Maybe they're not triggered by the usual things.

    And here's the critical part: don't present it to your practitioner with presumptions already baked in. Don't say, "Oh, my SIBO is flaring up again." Just describe what you're experiencing. Let them go through their checklist.

    The differential diagnostic list in functional medicine is way more expansive than in conventional medicine. That's both a gift and a challenge. We're thinking about things other practitioners might miss. But we cannot let that blind us to the conventional stuff.

    Being comfortable is not always a good thing. Experience helps us work faster, but complacency can be a real stealth enemy.

    That my friends, is definitely the reality of medicine, especially at the intersect of functional and conventional medicine. Worth it, but more work.

    In This Episode:

    • Why the differential diagnostic list matters for both practitioners and patients
    • The risk of getting too comfortable with chronic symptoms
    • How to communicate symptoms without presumptions
    • Balancing functional and conventional medicine approaches

    Key Takeaways:

    • When symptoms vary even by 20-30%, pay attention
    • Don't attach labels to your symptoms before presenting them
    • Practitioners must guard against overlooking conventional diagnoses
    • Clear communication protects both patient and practitioner

  • 05. From GI Struggles to Stability: Anti-Aging in Real Life
    Dec 28 2025

    From GI Struggles to Stability: Anti-Aging in Real Life

    A Patient Conversation with Jean

    In this episode, I’m joined by Jean, a long-time patient who generously shares her real-life health journey, not from a place of perfection, but from lived experience.

    This conversation is about what healing actually looks like over time. It is about chronic gut issues, instability, fatigue, and inflammation, but also about perspective, gratitude, resilience, and what it means to pursue longevity in a realistic, human way.

    What This Episode Covers

    • Jean’s transition into a new chapter of life, including relocation, retirement, and change
    • Years of chronic GI symptoms and the complexity of digestive healing
    • The role of journaling, self-awareness, and trial-and-error in recovery
    • How inflammation shows up across multiple systems over time
    • Why healing is often cyclical, not linear
    • What “anti-aging” really means outside of hype and extremes
    • The difference between chronological age and biological aging
    • How energy, cognition, stability, and connection define quality of life
    • The importance of movement, nature, sleep, and routine
    • Why social connection and lifelong learning matter for longevity
    • How to think through anti-aging options without overwhelm or fear

    A Realistic View of Longevity

    Rather than chasing every new trend, this episode walks through how to think clearly about longevity based on values, resources, tolerance, and life stage.

    We discuss data-driven strategies like nutrition, exercise, and inflammation reduction, alongside emerging longevity concepts, while always coming back to what is sustainable and meaningful for the individual.

    Key Takeaway

    Longevity is not about doing everything.
    It is about doing the right things for you, at the right time, in the right way.

    Stability, resilience, curiosity, and connection matter just as much as supplements or tests.

    And healing does not mean erasing the past. It means building a steadier future.

    Important Note

    This episode reflects a real patient conversation shared for educational purposes only. Nothing discussed should be taken as individual medical advice. Each person’s health journey is unique and should be navigated with appropriate professional support.

    Thank you to Jean for her honesty, wisdom, and willingness to share.
    This is what real-life healing looks like.
