Functional Medicine for Real-World Impact: The School of Applied Functional Medicine (SAFM)

Iron can be both life-saving and quietly destructive and understanding when it fuels healing versus when it drives inflammation is one of the most important clinical distinctions practitioners can make.

 

This episode invites practitioners to rethink iron as more than a lab value to correct or a supplement to prescribe. Tracy Harrison reframes iron as a powerful regulator of energy, immunity, brain function, and inflammation, one that requires nuance and restraint rather than automatic intervention. The conversation challenges the assumption that low hemoglobin or fatigue always calls for more iron and asks a bigger question about when the body may be intentionally limiting iron as a form of protection.

 

Rather than chasing numbers, Tracy emphasizes clinical context, regulatory intelligence, and root cause awareness. Iron can support vitality when handled with precision or quietly amplify oxidative stress and chronic disease when misunderstood. The takeaway is a shift in mindset: slower assessment, better questions, and treatment decisions that respect the system rather than override it.

A German-trained physician shares how functional medicine helped her finally understand why lifelong eczema persisted and what changed when she stopped chasing symptoms and started addressing immune overload.

 

In this episode, Tracy Harrison speaks with Julia Martin, MD, HC, about the gap between conventional medical training and real-world healing. Julia reflects on living with eczema since childhood, becoming a licensed physician, and realizing that much of what she learned focused on suppression rather than understanding why chronic conditions return. Discovering functional medicine shifted how she viewed immune activation, food sensitivities, and inflammation, leading to meaningful improvement in her own health.

 

The conversation explores Julia’s “inflammation bucket” framework, which explains how genetics, gut health, toxins, hormones, stress, and environment collectively shape symptoms over time. Rather than searching for a single trigger or cure, Julia emphasizes reducing overall immune load and empowering patients to respond calmly and confidently when flares occur. This episode shows how asking better questions and connecting systems can transform both practitioner confidence and patient experience.

What if your most powerful clinical tool is not another lab panel but the way you partner with patients around what their bodies already know?

 

Functional medicine PA Zoie Phillips joins Tracy Harrison to share how choosing integrity over a conventional career path led her to a values-based, telemedicine practice where patients act as true partners rather than passive recipients. She walks through her decision to commit to functional medicine straight out of PA school, her rocky attempt at a conventional job, and the moment she trusted her calling enough to wait for a role that actually fit. Along the way, Zoie explains how SAFM training helped her turn complex biochemistry into plain language, why education sits at the center of every visit, and how inviting patient intuition into the room often reveals clues no test would catch.

 

Zoie and Tracy also get honest about the slow, vulnerable early months of building a values-aligned practice, from financial reality checks and awkward networking attempts to the steady word of mouth that now fills Zoie’s schedule with patients who are ready to do the work. They talk about low stomach acid, trauma, and nervous system safety as hidden drivers of gut issues and explore why supplements alone never count as true root cause care. If you have ever wondered how to grow a functional medicine practice that honors your values, your bandwidth, and your patients’ autonomy at the same time, this conversation offers both caution signs and a hopeful, very human blueprint.

Hidden toxins in your air, products, technology and even inner dialogue may shape your patients’ physiology far more than their diet or exercise, and this conversation asks you to look at those influences through a sharper functional medicine lens. 

 

In this episode, Tracy Harrison breaks toxicity down into categories such as indoor air quality, fragrance and phthalates, plastics and microplastics, overlooked heavy metals and the constant load from screens and EMF, then connects each one to hormone balance, sleep, energy, mood and long term disease risk in ways you can act on in clinic. She also points out what might be the most powerful “toxin” of all, the critical voice in a patient’s head that keeps their nervous system locked in survival mode and quietly blocks detoxification and healing even when the clinical protocol looks solid on paper. 

 

Where could these hidden burdens be showing up in your patients’ homes, routines and thought patterns, and how might your plans change if you treated toxicity as a core clinical focus instead of a side note?

 

Episode Breakdown:

00:00 Introduction to Hidden Toxicity

02:48 Understanding Toxicity and Its Impact

10:49 Sources of Hidden Toxicity

18:25 The Role of Heavy Metals and Plastics

Dairy’s trusted role in patient diets shifts as Tracy Harrison breaks down how it can drive inflammation, immune reactivity, and persistent symptoms that rarely get linked to food in clinical practice. She explains why lactose intolerance is far more common than most patients realize, how whey and casein can contribute to skin issues, congestion, joint pain, fatigue, and histamine overload, and why some patients tolerate goat or sheep dairy better than cow dairy. Tracy also highlights the problem of hidden dairy in packaged foods and how it can undermine a structured elimination. 

 

This episode gives practitioners a sharper lens for assessing symptoms that look unrelated at first glance and a clearer path for deciding when dairy deserves closer investigation in a patient’s case.
