    Q&A. Why Do I Feel Depressed On Calcium-D-Glucarate?

    Have you noticed low mood or sadness after taking calcium D-glucarate? If you’re using it to support oestrogen detoxification or address high beta-glucuronidase on a gut test, your stage of life and hormone levels deserve consideration.

    60. The Gut and Immune System: The Histamine Connection

    Could your gut help explain why you’re reacting to foods you once tolerated? In this episode of The Histamine Well, Joanne explores the connection between gut health and histamine intolerance, explaining how the microbiome, intestinal lining, immune system, and nervous system interact.

    58. Biofilms: Why SIBO, Candida & Gut Infections Keep Coming Back

    Why do SIBO, Candida, and other gut infections sometimes return—even after treatment initially seems successful? In this episode of The Histamine Well Podcast, Joanne explains how biofilms may contribute to persistent bacterial and fungal overgrowths.

She also explains how bacteria and fungi can communicate, share resources and coexist within mixed-species biofilms. You’ll discover: What biofilms are and why microorganisms create themWhy SIBO, Candida and gut infections may keep returningHow biofilms can protect bacteria and fungiThe connection between biofilms, chronic sinus infections and MARCoNSHow Candida and Aspergillus form fungal biofilmsThe difference between mould, mycotoxins and biofilmsWhat the biofilm matrix is made fromHow enzymes and N-acetylcysteine may support biofilm disruptionWhy biofilm support should be introduced gradually during antimicrobial treatmentIf you’re dealing with recurring digestive symptoms or want to better understand persistent microbial overgrowths, this episode offers a clear and practical introduction to biofilms and their potential role in gut and sinus health. ✨ Want more?

    Q&A. Why Do I Feel Sick From Having an Epsom Salt Bath?

    Do you feel nauseous, dizzy, exhausted, or brain foggy after an Epsom salt bath? If a bath you hoped would help you relax leaves you feeling worse, you might wonder whether you’re experiencing a “detox reaction,” reacting to the heat or struggling to tolerate the Epsom salts themselves. In this short Q&A episode of The Histamine Well Podcast, Joanne explores possible reasons for feeling sick after an Epsom salt bath, including bath temperature, changes in blood pressure, histamine intolerance, mast cell activation and sensitivity to sulfur compounds. Epsom salts are magnesium sulfate. Joanne explains the role of sulfate in a detoxification pathway called sulfation and discusses why people use Epsom salt baths as part of their detox routines. She also shares why feeling unwell afterwards should not automatically be interpreted as a sign that a treatment is working—or a reason to push through. If you’ve been searching for answers about Epsom salt bath side effects, feeling dizzy after a hot bath, or the possible connection between histamine intolerance and Epsom salts, this episode offers a starting point for understanding your reaction and discussing it with your practitioner. ✨ Want more?
