Our immune system operates like a finely tuned symphony, yet many of us find ourselves out of harmony, vulnerable to persistent infections, autoimmune conditions, and chronic disease. Rather than merely suppressing symptoms, a Functional Medicine approach seeks to identify and address the underlying disruptions driving immune imbalance. Central to this dysfunction is compromised gut health, which undermines immune regulation, while mitochondrial impairment and chronic inflammation further erode the body's capacity for resilience and repair. By restoring balance at the root level, we can cultivate a more robust and adaptive immune system. In this episode, I discuss, along with Dr. Elroy Vojdani and Dr. Leonard Calabrese, how cleaning up our diets, improving gut health, removing toxins, and decreasing stress can do wonders for our immune systems. Dr. Elroy Vojdani is a pioneer in the field of functional medicine and research and is the founder of Regenera Medical, a concierge functional medicine practice in Los Angeles, California. He graduated from USC Keck School of Medicine, is a certified Institute for Functional Medicine Practitioner. Dr. Vojdani has conducted medical scientific research for decades with more than 25 publications in multiple peer-reviewed journals. He is also world-renowned for his research and development of state-of-the-art lab testing in the field of immunology. He recently authored a book entitled “When Food Bites Back” which discusses the role of food immune reactions in the development of autoimmune disease.  Dr. Leonard Calabrese, is an expert in immunology and rheumatology. In fact, he is a Professor of Medicine at the Cleveland Clinic Lerner College of Medicine of Case Western Reserve University and Vice Chair of the Department of Rheumatic and Immunologic Diseases.
