Histamine Well Podcast: Exploring Histamine, Methylation & Holistic Health

49. Mould & Mitochondria: Why You're Still Exhausted (and What's Really Driving It)

Persistent fatigue is one of the most common—and most frustrating—symptoms experienced by people with mould illness. Many find that despite sleeping more, resting, pacing themselves, and trying countless supplements, the exhaustion simply doesn't improve. In this episode of The Histamine Well Podcast, Joanne explores the hidden connection between mould illness and mitochondrial dysfunction, revealing why fatigue can persist long after mould exposure has been identified. You'll learn how three key factors often work together to impair cellular energy production: * Mycotoxins and their direct toxic effects on mitochondria * Sulfur depletion and reduced glutathione production * Oxalate accumulation and mitochondrial stress Joanne explains how these mechanisms can disrupt ATP production, increase oxidative stress, and contribute to symptoms such as chronic fatigue, brain fog, muscle weakness, exercise intolerance, post-exertional malaise, pain sensitivity, and temperature dysregulation. This episode also explores the important relationship between mould exposure, gut dysbiosis, SIBO, sulfur metabolism, and oxalate overload—factors that are frequently overlooked when addressing ongoing fatigue and recovery from mould illness. Whether you're a practitioner, student, or someone navigating chronic health challenges, this episode provides valuable insights into the biological processes driving fatigue and what may need to be addressed for meaningful recovery. In this episode, you'll discover: * How mould toxins damage mitochondrial function * Why fatigue often persists despite rest and sleep * The critical role of sulfur in energy production and detoxification * How oxalates can contribute to mitochondrial dysfunction * Common signs of mould-related mitochondrial impairment * Why addressing mould exposure alone may not be enough for recovery ✨ Want more?

48. How Mould Mycotoxins Cause SIBO

In this episode of The Histamine Well Podcast, Joanne explores the hidden connection between mould mycotoxins and Small Intestinal Bacterial Overgrowth (SIBO) — and why so many people with chronic digestive symptoms may be missing the true root cause of their gut dysfunction. If you’ve been struggling with bloating, reflux, constipation, diarrhea, histamine intolerance, food sensitivities, nausea, fatigue, or recurring SIBO that never fully resolves, this episode explains how mould exposure may be contributing to ongoing nervous system and digestive dysfunction. Joanne breaks down the mechanisms behind mould-related gut issues, including how mycotoxins impact the vagus nerve, gut motility, stomach acid production, bile flow, pancreatic enzymes, inflammation, and the migrating motor complex. She also discusses why chronic SIBO cases are often difficult to treat when mould toxicity is not properly addressed. In this episode, you’ll learn: * Why mould illness and SIBO commonly occur together * How poor vagal tone affects digestion and bacterial overgrowth * The connection between mould, histamine intolerance, and mast cell activation * Why low stomach acid and sluggish bile flow can worsen gut symptoms * How chronic inflammation disrupts gut motility and digestive function * Why antibiotics and herbal antimicrobials may not fully resolve SIBO * The importance of mould testing in chronic gut health conditions #SIBO #MouldIllness #HistamineIntolerance #GutHealth #Mycotoxins #MCAS #FunctionalMedicine #DigestiveHealth #MoldToxicity #VagusNerve ✨ Want more?

47. The Bile-Histamine Connection: SIBO, Estrogen, Mold & Oxalates Explained

What if your histamine symptoms aren’t just about food? In this episode of the The Histamine Well Podcast, Joanne explores the overlooked connection between bile flow, histamine intolerance, SIBO, estrogen dominance, mold exposure, oxalates, methylation, and chronic inflammation. Bile plays a critical role in digestion, detoxification, hormone clearance, and microbial balance in the gut. When bile flow becomes sluggish, it can contribute to bacterial overgrowth, poor fat digestion, impaired estrogen detoxification, oxalate accumulation, and worsening histamine symptoms. In this episode, Joanne explains: * How poor bile flow contributes to histamine intolerance * Why mold toxicity and mycotoxins affect the liver and gallbladder * The vicious cycle between SIBO and bile dysfunction * How estrogen dominance impacts bile flow and histamine * Why oxalates can worsen inflammation and histamine symptoms * The role of methylation and phosphatidylcholine in healthy bile production * How vagus nerve dysfunction affects digestion and bile release * Common signs and symptoms of poor bile flow This episode is essential listening for anyone struggling with histamine intolerance, MCAS, gut health issues, bloating, hormone imbalances, mold illness, chronic inflammation, food sensitivities, or unexplained digestive symptoms. 🎧 Subscribe to The Histamine Well Podcast for evidence-based conversations on histamine intolerance, methylation, SIBO, mold illness, women’s hormones, and functional medicine. #HistamineIntolerance #SIBO #GutHealth #MoldIllness #EstrogenDominance #Oxalates #Methylation #FunctionalMedicine #BileFlow ✨ Want more?

46. High Homocysteine: Histamine, Methylation & Why You Might Not Tolerate Methylated B Vitamins

Can methylated B vitamins make your symptoms worse instead of better? In this episode of The Histamine Well Podcast, Joanne explains the connection between high homocysteine, histamine intolerance, methylation, and why some people react poorly to methylated nutrients. High homocysteine is associated with cardiovascular disease, cognitive decline, inflammation, and neurological health concerns — yet lowering it isn’t always simple. Many people experience headaches, anxiety, insomnia, digestive issues, skin flare-ups, or worsening histamine symptoms when taking methylfolate or methyl B12. Joanne breaks down the methylation cycle in simple terms, explains the role of histamine in nutrient tolerance, and explores how genetics such as the MTHFR gene mutation and COMT enzyme activity may influence how your body responds to methylated supplements. In this episode, you’ll learn:  • What high homocysteine means and why it matters  • The connection between homocysteine and methylation  • Why methylated B vitamins can trigger symptoms  • Histamine intolerance and supplement sensitivity  • The role of MTHFR, COMT, and methylation pathways  • Overmethylation vs undermethylation explained  • Practical clinical insights for improving tolerance to methyl nutrients Whether you're a practitioner, student, or navigating your own health journey, this episode offers practical education on histamine, methylation, gut health, and root-cause healing.

Q&A. Should I Take Calcium-D-Glucarate Whilst On HRT Oestrogen?

Can you take Calcium-D-Glucarate while on HRT estrogen during menopause? In this short Q&A episode of The Histamine Well Podcast, Joanne explores the relationship between estrogen detoxification, hormone replacement therapy (HRT), menopause, gut health, and histamine-related symptoms. Many women are advised to take supplements that support estrogen detox, but is this always the right approach when using bioidentical hormones or estrogen therapy? Joanne explains why Calcium-D-Glucarate may not be beneficial for menopausal women on HRT, how estrogen balance works during menopause, and why understanding your hormone dose matters for symptom relief and long-term wellbeing. This episode also covers: *  The role of estrogen during menopause and HRT  *  Why over-detoxifying estrogen may worsen symptoms  *  The connection between beta-glucuronidase, the estrobolome, and gut microbiome health  *  Histamine intolerance, hormone imbalance, and menopause symptoms  *  Natural considerations for estrogen metabolism and hormone support  *  Why gut health may be more important than estrogen detox supplements  If you're navigating menopause, hormone replacement therapy, estrogen dominance symptoms, histamine intolerance, or gut-related hormone imbalance, this episode offers practical clarity backed by clinical naturopathic insight.  Subscribe to The Histamine Well Podcast for expert conversations on histamine intolerance, methylation, gut health, hormones, mold illness, MCAS, menopause, and functional medicine approaches to healing. ✨ Want more?
