    42. Health Advice on Social Media: How to Know Who to Trust with MaryJo Anderson

    You've read the posts, watched the reels, maybe dropped your lab results into ChatGPT late at night, and you still don't know what to do next. When three doctors give you three different answers and your feed offers a new diagnosis every morning, the hardest part becomes knowing who to trust. Why this episode matters MaryJo Anderson saw 50 doctors over four years before she found answers for chronic Lyme disease. Nine months after sharing her story on this podcast, she's back with Dr. Su to talk about what happened next, including the flood of messages from women sorting through hormones, hysterectomy decisions, and conflicting medical advice. After ten years of building a community on Instagram, she has a clear view of how health advice on social media shapes the decisions people make, and Dr. Su sees the other side of it every week in his practice. What you'll learn Why more health information hasn't made decisions easier, and what MaryJo does before she acts on anything she readsWhat Dr. Su notices when patients arrive with AI-interpreted labs or a diagnosis they've already settled onHow online awareness can keep one person stuck while finally getting another person the help they neededThe practical difference between discernment and judgment, and how to use it with your feed, your supplements, and your doctorsKey themes Self-advocacy takes time: reading first, interviewing two or three providers, and turning down the noiseThree doctors, three answers: what to do when the experts disagreeHow algorithms feed you more of whatever you searched last, including symptomsThe pressure on women (and now young men) to buy what they're told they needAbout MaryJo Anderson MaryJo Anderson is a mom of three and a content creator who has spent ten years building a close community of women on Instagram. After years of unexplained symptoms and 50 doctors, she was diagnosed with chronic Lyme disease and shared her full story on the Functional Medicine Reality Podcast earlier this year. She returns as a recurring co-host to talk about patient advocacy, women's health, and staying discerning online. Dr. Su's perspective "More information saying the same thing doesn't mean it's accurate, or the best answer for you. There are shades of gray, and sorting through it takes time and effort." Dr. Su has spent 23 years helping patients who arrive overwhelmed by conflicting input. His goal is never to talk someone out of their research. It's to help them keep an open mind long enough to find what's driving their symptoms, so they can get better, faster. MaryJo and Dr. Su also agreed this conversation needs a Part Two on social media and mental health, so stay tuned. Have a question for Dr. Su? Once a month, Dr. Su opens one hour to five people only.

    41. Why Your Doctor Shuts Down Supplement Questions (And What Should Happen Instead)

    You've asked a doctor about a supplement, an herb, or a therapy like hyperbaric oxygen or ozone, and gotten a flat "that doesn't work" in return, with no real explanation and no room for follow up questions. Why this episode matters: Dr. Su has watched this happen to his own patients for years. In this episode he names exactly what's going on and gives it a term, ontological humility, the simple idea that we don't know what we don't know. He applies it to both sides of the exam room, and by the end you'll understand not just why doctors dismiss what they don't know, but why patients need to ask the same honest questions about the herbs and supplements they trust. What you will learn: Why conventional doctors often say "it doesn't work" when the honest answer is "I don't know enough to say" Why "natural" doesn't automatically mean "safe," and what's actually missing from the research on herbs and supplements How to think about the real risk of what you're taking, instead of assuming risk is zero because it came from a health food store Key themes: Ontological humility as a framework for honest practice The time crunch behind conventional medicine's dismissiveness The unregulated gray zone of supplement and herbal research  Dr. Su doesn't let either side off the hook here. He's direct that dismissing a therapy just because you're unfamiliar with it is unfair and unjust, and he's equally direct that assuming a supplement is safe just because it's not a pharmaceutical is its own kind of unearned confidence. His answer isn't to pick a side, it's to be honest about what's actually known and unknown, and to weigh real risk before making a decision.  Get your free Lab Results Guide: https://labsoptin.rootseekhealth.com/labs/ Have a question for Dr. Su?

    40. The Brain Health PlayBook with Dr. Trevor Berry

    Most of us will get our teeth cleaned twice this year and never think once about our brain. That's the gap Dr. Mark sits down with Dr. Trevor Berry to close in this episode. Why this episode matters: Dr. Berry is a board-certified chiropractic neurologist and co-founder of Brain Restore Centers, a fast-growing national network built around a hard fact, the changes behind conditions like Alzheimer's and Parkinson's can start twenty to thirty years before anyone notices a symptom. By the time memory loss or brain fog shows up, the process is already well underway, and waiting for symptoms means waiting too long. What you will learn: The four foundational pillars Dr. Berry uses to protect and rebuild brain function, movement, low-level laser therapy and photobiomodulation, oxygen therapies, and nutritionWhy brain fog and fatigue deserve the same root-cause investigation as any other chronic symptom, instead of getting dismissed as normal aging or stressWhat objective testing for brain health actually looks like, from cognitive assessments to balance and blood flow markersWhy prevention has to start decades before symptoms, and what "prevention" actually looks like day to dayKey themes: Root-cause thinking applied to the brainMovement, light, oxygen, and nutrition as the real foundations of brain healthChronic stress and its long-term effect on the brainWhy one modality alone rarely gets the full resultDr. Su's perspective: Dr. Mark has known Dr. Berry for a couple of years, and this conversation grew out of watching his approach up close. What stood out most was the objective side of it, the idea that brain health doesn't have to stay subjective or vague. There are real markers you can track and real progress you can measure, and that's the same root-cause philosophy RootSeek applies to every other system in the body.

    39. Why We Built a Transparency-First Functional Medicine Podcast

    If you've ever wondered what you're actually getting when you walk through the door of a functional medicine practice, you're not alone. It's a crowded field, and there's no easy way to know what a given practitioner will actually be like until you've experienced it firsthand. Why this episode matters: In this episode, Dr. Mark Su steps back from the usual format of the show to explain exactly why the Functional Medicine Reality Podcast exists. This isn't a sales pitch and it never has been. Dr. Su built it to give people considering root-cause medicine, and specifically considering RootSeek Health, a transparent look at who they'd be trusting with their care before they ever book a visit. What listeners will learn: Why Dr. Su started this podcast, and why it was never meant to build audience or revenueHow the show is structured, rotating between professional interviews and unscripted patient consultationsWhy Mike Schrantz and Mary Jo Anderson return as recurring co-hosts, and what each brings to the showWhy the patient interviews are real, unscripted consultations, not scripted contentHow to get a free consultation with Dr. Su by sharing your story on the podcastKey moments or themes: The show's rotating format: two out of every four episodes are professional interviews, two are patient conversationsMike Schrantz as the recurring "doctor of homes," covering the intersection of environmental illness and clinical careMary Jo Anderson's ongoing story, from chronic Lyme disease to longevity optimizationThe invitation for listeners to be interviewed as patients in exchange for a free consultationDr. Su's perspective: At the six-month mark, Dr. Su reflects on the feedback the show has received and reaffirms its singular goal: helping people who've been dismissed by conventional medicine feel confident that someone finally believes them and has a plan.

    38. Christine's Story on Hormones, ADHD, and Getting Her Life Back

    You've probably been told your labs look fine while you're barely functioning. That gap, between what a lab report says and what your body is actually telling you, is exactly where this episode lives. Christine has been a patient of Dr. Su's for over fifteen years, and this conversation traces her whole arc, from years of unexplained symptoms that finally led to a Lyme disease diagnosis, through a mold reaction, and into the last five months, where three specific changes stacked together and took her vitality from a self-rated three out of ten to a consistent eight or nine. What you will learn: Why a body composition scan gave Christine real numbers instead of vague impressions, and how tracking muscle mass percentile (not just weight) became a starting point she could actually work fromHow hormone replacement therapy changed her ability to follow through on things, not just how she felt day to dayWhy properly managed ADHD medication, paired with better sleep and exercise, gave her the executive function to organize her whole routine around the other changesKey themes: What it took to finally get a Lyme disease diagnosis after over a decade of unexplained symptomsWhy gradual decline is so hard to notice and even harder to advocate for yourself againstHow several right-fit interventions, stacked together, can move the needle faster than any single one aloneDr. Su: "What stands out most in this conversation isn't any single treatment. It's the sequence. Christine had spent over a decade working through Lyme and mold before we ever got to hormones and ADHD medication. Each piece mattered, and each piece needed the ones before it. That's usually how real change works. It's rarely one thing." Guest bio: Christine" is a longtime RootSeek patient whose name has been altered to protect her privacy. She works in IT and has been under Dr. Su's care for over fifteen years, through a Lyme disease diagnosis, a mold reaction, and most recently, a five-month stretch of change involving body composition testing, hormone replacement therapy, and ADHD medication management.

    37. GLP-1s: The Science Explained, A Doctor and a Patient's Real Take

    You've watched GLP-1s take over every feed, every ad, every conversation at a family gathering, and you're still not sure what to believe. Is it legit? Is it safe? Is it just the easy way out? Why this episode matters:  GLP-1s and peptides have gone from a niche diabetes medication to a full-blown cultural moment in just a few years, and the information hasn't kept up with the demand. Dr. Su and Mary Jo sit down for an honest, unfiltered conversation about what's actually happening in the body, where the confusion comes from, and why the stigma around using them deserves a second look. What you will learn: The real mechanism behind GLP-1s, and how tirzepatide differs from semaglutideWhy sourcing peptides has become what Dr. Su calls a wild west, and what that means for your safety and your walletWhere the "easy way out" stigma comes from, and why Dr. Su pushes back on it clinicallyWhat Mary Jo experienced firsthand over two years on semaglutide, including inflammation, energy, and the harder truth about what happens when you stopThe evolving research connecting GLP-1s to mast cell regulation and inflammation, beyond weight loss aloneKey themes: The gap between how GLP-1s are marketed and how they actually workStigma, gender, and the quiet judgment around using medication for weightCost, access, and how to avoid getting overcharged for microdosing or unreliable sourcingDr. Su's perspective: Dr. Su is direct about where he stands. He's seen GLP-1s change the trajectory of patients' health, not just their weight, and he's equally direct that the "did you earn this the hard way" question misses the point entirely. His focus stays on what actually helps someone get better, faster, and at a cost that doesn't take advantage of them.

    36. Doctor First or Inspector First: What to Do When You Suspect Mold Illness with Mike Schrantz

    You've read about mold. You've read about CIRS, mycotoxins, water damage, and now maybe even bacteria, and it's a lot. So you start looking into an environmental inspection, wondering if your house is behind the fatigue, the brain fog, the symptoms nobody's been able to explain. Why this episode matters: Dr. Mark Su sits down with Mike Schrantz, CIEC, one of the most connected indoor environmental professionals in the country, to talk about a pain point that shows up again and again in both their practices, patients starting their mold illness journey with an inspector before a clinician is ever involved. It's a conversation that rarely happens out loud, two professionals from different sides of the same problem comparing notes on where the process breaks down. What you will learn: Why starting with an environmental inspector before a doctor often leads to confusion, wasted money, and testing that doesn't answer the real questionThe difference between a targeted assessment and a whole-house assessment, and why that choice matters more than most people realizeWhat a clinician actually adds to the process that an inspector can't, and vice versaKey themes: The order of operations matters, clinician first, then environmental testingCost and scope decisions get a lot easier once a doctor has narrowed the focusThis is often a team effort between two professionals working toward the same goal, a patient who finally has answersDr. Su's perspective: Dr. Su has seen this pattern often enough to know it's rarely anyone's fault. Patients are doing their best with the information available to them, and that information usually points them toward testing before it points them toward a doctor who can make sense of the results. His take throughout the conversation is straightforward, if you have chronic symptoms that aren't going away and you have real concerns about your environment, it's worth having a clinician involved somewhere along the way, earlier rather than later. If this sounds like where you are right now, a Clinical First Steps Call with Dr. Su is a good next step before you spend a dime on testing. Book yours at go.rootseekhealth.com/askdrmark.

    35. Mobility vs. Stability: What Your Pain Treatment Might Be Missing, with Dr. Mike Melander

    If you've done months of physical therapy or chiropractic care and your pain still hasn't moved, you're not imagining it, and you're not doing it wrong. Something in the plan was probably missing from day one. Why this episode matters: Most pain treatment starts with the same assumption: get stronger. But strength only works within the range of motion you actually have access to. If a joint can't move the way it's supposed to move, no amount of strengthening will fix it, and in some cases, it can make things worse. Dr. Su sits down with Dr. Mike Melander, a chiropractor and Active Release Technique instructor, to explain the question almost no one asks before starting treatment. What you will learn: The difference between a mobility problem and a stability problem, and why it changes everything about a treatment planWhat "tissue quality" means, and why pain itself is an unreliable way to judge what's happening in a muscleWhy fibromyalgia and chronic Lyme patients often carry real, findable tissue issues, even when the root cause isn't musculoskeletalWhy chiropractic care and physical therapy work best together, not as competing approachesKey themes: Root-cause thinking applied to pain, not just complex chronic illnessThe overlap between structural pain and systemic conditions like Lyme and fibromyalgiaWhy "call me if you need me" is sometimes the best plan a provider can offerDr. Su's perspective: Dr. Su draws a direct line between what Dr. Melander does with tissue and joints and what RootSeek does with labs and systems. The tools are different, but the instinct is the same: don't stop at the first plan, look for what's actually driving the problem.  If this conversation named something you've been living with, whether it's pain that won't resolve or a chronic illness that hasn't had a clear answer, Dr. Su opens one hour a month to five people for real, direct guidance.   Book your spot: rootseekhealth.com/askdrmark Free Lab Guide: rootseekhealth.com/opt-in Links: North Shore Spine and Sport: northshorespinesport.comRootSeek Health: https://rootseekhealth.com/Guest bio: Dr. Mike Melander, DC is a chiropractor with 16 years in clinical practice and a multi-time Best of Boston winner.
