In this episode, we’re uncovering a misunderstood and often hidden contributor to chronic symptoms in autoimmunity: mast cell activation syndrome (MCAS) — and why your body may be reacting to food, supplements, and even stress like it’s under constant attack.

Join VJ Hamilton, registered nutritionist and autoimmune health specialist, as we dive into the science behind MCAS, how it overlaps with autoimmune conditions like Hashimoto’s, lupus, and rheumatoid arthritis, and what you can do to calm your immune system from the inside out.

You’ll discover:

• What MCAS is and how it mimics or overlaps with other autoimmune and chronic illnesses
• Why some people produce too much histamine and can’t clear it effectively — the “double whammy” of MCAS and histamine intolerance
• Root causes and triggers of MCAS, including mould exposure, infections, oestrogen dominance, and nervous system dysregulation
• How trauma, chronic stress, and vagus nerve dysfunction keep your immune system on high alert
• Nervous system tools that help “retrain” mast cells — including somatic therapy, vagus nerve practices, and Nurosym
• The role of supplements like quercetin, vitamin C, luteolin, DAO enzyme, and magnesium glycinate in calming mast cells
• When to seek help and how to navigate MCAS testing and therapeutic trials with the right support

Plus, I share practical, evidence-informed strategies to reduce triggers, nourish your nervous system, and take a systems-based approach to MCAS — even without a formal diagnosis.
