Megan Pennington | BSc Clinical Nutrition (McGill University) | Certified LEAP Therapist (CLT)
You've seen the doctors. You've tried the diets. You've done the research at midnight when the pain wouldn't let you sleep. You've spent money, time, and hope on things that helped a little — or not at all. And somewhere along the way, a quiet fear crept in: maybe this is just how my life is going to be.
It's not. You're not broken. You've just never had a map specific enough to your body.
Most approaches — even good ones — are built around averages. They treat the category of your condition, not the specific triggers driving your inflammation. That's the gap. And it's exactly what we close.
At MP Integrative Health, we use advanced functional testing and a proven clinical protocol to identify the exact foods and factors activating your immune system — then build a plan around your unique biology. Not a template. Not guesswork. A precise, personal roadmap to healing.
Typical symptom reduction within the first 2 weeks

Clinical experience helping chronic conditions others couldn't resolve
Over 20 years ago, Megan chose to dedicate her career to the people conventional medicine had stopped exploring answers for—those with stacks of "normal" test results who were anything but well, quietly managing symptoms while grieving the life they once had.
She holds a BSc in Dietetics and Human Nutrition from McGill University and is a Certified LEAP Therapist — one of a select group worldwide trained in the advanced MRT/LEAP food sensitivity protocol. As founder of MP Integrative Health and a 2025 Global Recognition Award Winner, she has helped hundreds of clients across the US and Canada achieve lasting relief from conditions that had resisted every prior attempt at treatment.
Her approach is precise, science-based, and deeply personal — because she knows that behind every chronic condition is a person who deserves more than symptom management.

I was desperate to find help for my severe Crohn's disease. Finding Megan is the best thing to happen to me since my diagnosis nearly 10 years ago. Within days of starting my individualized program I had no pain, no diarrhea, no bloating and more energy than I've had in years.
After 25 years of medication for digestive, blood pressure, and cholesterol issues, I finally have my health back thanks to this program. My energy is back, I've lost that belly fat that would not let go along with bloating, allergies are almost non-existant, BP medication is no longer needed, and I can't wait to have my cholesterol checked! Best of all, my aches and pains are gone.
Here's the honest truth: most approaches fail, not because you're doing the wrong things, but because you've only been given a few pieces of the puzzle. Our approach works because it addresses the primary drivers of your condition simultaneously, creating effective and lasting results.
This is where everything changes. We use Mediator Release Testing (MRT), the most clinically accurate food sensitivity test available, to measure how your immune system actually responds to 175+ specific foods and chemicals. Not IgG guesswork. Not a standard elimination list. Your actual immune data.
This is why clients who've tried every diet for years finally see results in weeks. We're not removing the wrong things anymore.
Your MRT results become the foundation of your personal LEAP Protocol, a phased eating plan that starts with your lowest-reactive foods and expands as your gut heals. No restriction for restriction's sake. Every choice is intentional and specific to your biology.
Most clients experience 50–80% symptom reduction within 2 weeks. Not because it's magic, because it's finally precise.
Removing triggers stops the fire. But if leaky gut, microbial imbalance, and chronic inflammation have been building for years, the structure itself needs repair. This is the work that transforms feeling better into actually healed. We support your gut lining, restore microbial balance, and address physiological damage that has accumulated over time.
External triggers are not the only cause of inflammation and disease. Years of pain, stress and uncertainty actively impact your immune system, your nervous system, and your body's ability to heal. For clients who choose to include this piece, we offer evidence-based mind-body tools to help your mental-emotional systems to recalibrate and allow for faster, deeper healing.
These are the conditions we work with most. What they share: they're driven by underlying inflammation, they respond poorly to symptom-only treatment, and they change profoundly when the right triggers are identified and removed.
Inflammation doesn't pause while you wait. Take the first step.
Start NowVirtual appointments available across the US and Montreal.
Our patients often tell us how relieved they felt just to have a clear path. No more guessing. No more starting over. Here's exactly what the process looks like.
We start by truly understanding your story — your health history, your symptoms, what you've already tried, and what you're hoping for. This isn't a rushed intake. It's a real conversation. All appointments are virtual via secure video or phone, so you can access care wherever you are.
A testing kit is mailed directly to you. You arrange a local blood draw (we walk you through every step), and the sample goes to our certified lab. Results return within 7–10 business days, providing a clear list of triggers.
We review your results together in detail and design your LEAP Protocol — a phased plan built around your specific biology. You'll understand exactly why each recommendation is included, and you'll have a clear, manageable plan from day one.
You're not handed a plan and left alone. We track your progress with specialized tools, adjust as needed, and provide regular check-ins and support throughout. You also get access to our full healing toolkit — recipes, resources, and advanced mind-body practices (if you choose).
As symptoms resolve, we systematically reintroduce foods and build your sustainable long-term plan. The goal isn't to keep you dependent on our assistance — it's to give you back your life, your energy, your body. And the knowledge to keep it.
My naturopath was genuinely surprised at how much my intestines have improved. The villi and microvilli of my small intestine tested as healed! The entire process has helped to resolve several longterm issues, including intolerance and intestinal pain after eating most food. I am deeply grateful for all your assistance.
I have been active all my life and done my best to eat healthy. What I didn't know is that some foods which are considered healthy were not good for my body. At 54, I had developed arthritis in my neck and knees, which caused numbness and made everyday activities difficult. My knees started feeling better after just a few days on the program. My head is clearer and I am more productive. The IBS I've had throughout my life is healing. I am immensely grateful for Megan's guidance and this amazing healing.
Our protocols are built on published research — not trends.
Peer-reviewed research consistently demonstrates that food-induced immune responses drive chronic inflammatory conditions, and that personalized elimination diets based on proper testing significantly reduce symptoms.
Research: Diet and Inflammation →Intestinal permeability and microbiome dysbiosis are documented underlying factors in autoimmune disease and chronic inflammation — making gut healing a core part of any lasting protocol.
Research: Leaky Gut & Systemic Inflammation →MRT has been clinically validated with significantly higher accuracy than IgG and other intolerance tests.
Research: MRT Clinical Validation →Chronic stress activates inflammatory pathways and impairs immune regulation — making nervous system support an evidence-based, not optional, part of chronic disease management.

We always recommend maintaining care with your primary physician alongside our program. This is integrative care — it works with your medical team, not against them.
Imagine waking up without dreading how your body will feel. Eating without fear. Having your life back. The risk isn't in moving forward — it's spending another year with no results.
