Autoimmune Provider in Jacksonville & North Florida
At Foundational Health, we specialize in helping individuals in Jacksonville and Jacksonville Beach, FL, find real answers to autoimmune conditions that have been overlooked or dismissed. Whether you’re struggling with Hashimoto’s, Rheumatoid Arthritis, Lupus, Psoriasis, or another autoimmune diagnosis, our comprehensive and integrative approach gets to the root of immune dysfunction. We combine advanced diagnostics, functional medicine, and brain-based therapies to support lasting immune regulation and whole-body healing.
What Is Autoimmune Disease?

Autoimmune disease occurs when the immune system mistakenly attacks healthy cells and tissues. With over 80 different types identified, autoimmune disorders can impact nearly every part of the body. Common symptoms include chronic fatigue, joint pain, digestive issues, brain fog, and skin conditions. Often, patients are told their labs are normal or are placed on symptom-masking medications. At Foundational Health, we work to uncover the underlying causes driving immune dysfunction—from gut imbalances and chronic infections to toxic exposures and stress overload
Our Approach to Autoimmune Healing Root-Cause Medicine That Listens and Understands
Instead of suppressing the immune system, we aim to restore its balance. Our process begins with an in-depth evaluation of your personal and family history, environment, and past lab results. We utilize advanced testing to identify immune triggers, nutritional deficiencies, and patterns of inflammation. Our care plans include targeted nutrition, gut healing protocols, neurological therapies, and lifestyle support designed to calm the immune system and promote resilience.

How Functional Medicine Helps Autoimmune Patients
Autoimmune diseases are not one-size-fits-all, and neither are our treatments. Functional medicine recognizes that each person’s immune response is shaped by their environment, genetics, infections, and internal chemistry. By addressing the total picture of health—including brain-body communication, detoxification, and inflammation—we’re able to help our patients break free from the cycle of flare-ups and fatigue.
Individualized Diagnostics & Treatment
We dig deep into your history and biology to identify the hidden factors contributing to immune dysregulation.
Gut-Immune Healing Protocols
Because 70% of the immune system resides in the gut, our protocols focus heavily on restoring gut health to reduce systemic inflammation.
Brain-Based Immune Support
We include therapies that retrain the nervous system, reduce stress chemistry, and improve immune coordination between brain and body

We work with a wide range, including Hashimoto’s, Rheumatoid Arthritis, Lupus, Sjogren’s, Psoriasis, MS, and autoimmune-related digestive conditions like Celiac or Crohn’s.

While there is no “cure,” many patients experience remission, reduced symptoms, and improved quality of life through our root-cause approach.
