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 intoleranceWhy mold toxicity and mycotoxins affect the liver and gallbladderThe vicious cycle between SIBO and bile dysfunctionHow estrogen dominance impacts bile flow and histamineWhy oxalates can worsen inflammation and histamine symptomsThe role of methylation and phosphatidylcholine in healthy bile productionHow vagus nerve dysfunction affects digestion and bile releaseCommon signs and symptoms of poor bile flowThis 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?

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 nutrientsWhether 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.Subscribe to The Histamine Well Podcast for expert discussions on histamine intolerance, women’s hormones, functional medicine, gut health, methylation, and integrative wellness.✨ Want more?

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.

Do you find your anxiety worsening at night—or waking you suddenly between 2AM and 4AM with a racing heart and intrusive thoughts?In this Clarity Session Q&A, Joanne explores one of the most common patterns seen in clinic: night-time anxiety and early morning wake-ups—and why this is often more than just a psychological issue.This episode explains the physiological root causes of anxiety at night, including the critical role of blood sugar regulation, liver glycogen stores, and stress hormones like cortisol and adrenaline. When blood sugar drops overnight, your body triggers a stress response—leading to symptoms that can feel like panic attacks. You’ll learn: Why anxiety often spikes between 2AM–4AM The connection between low blood sugar and night-time panic How cortisol and adrenaline disrupt sleep Common triggers like skipping meals, low protein intake, and caffeine use Why this pattern is especially common in perimenopause Simple strategies to stabilize blood sugar and improve sleep qualityJoanne also shares practical tips, including how a protein-based evening snack may help prevent early morning wake-ups and reduce overnight anxiety.If you’ve been struggling with disrupted sleep, anxious thoughts at night, or waking at 3AM feeling wired, this episode offers a new perspective—and actionable steps to support your body.✨ Want more?

If your blood tests are “normal”… why do you still feel inflamed?In this Q&A Clarity Session of The Histamine Well Podcast, Joanne answers a deeply important and often overlooked question: why symptoms of inflammation can persist even when CRP and ESR markers come back normal.Many people are told everything is “fine” based on standard blood work—yet continue to experience fatigue, brain fog, skin issues, gut dysfunction, and hormonal imbalances. This episode explains why that disconnect happens and what may actually be driving your symptoms.CRP (C-reactive protein) and ESR (erythrocyte sedimentation rate) are commonly used markers for inflammation—but they primarily detect acute, systemic inflammation, not the chronic low-grade inflammation seen in many complex health conditions. In this episode, you’ll learn: Why CRP and ESR can be normal despite ongoing symptoms The difference between acute vs chronic low-grade inflammation Common drivers of hidden inflammation (gut issues, histamine, mold, blood sugar imbalance, stress) How inflammation can show up as skin, neurological, hormonal, and digestive symptoms Why patients are often dismissed despite real underlying issues If you’ve ever been told “your labs are normal” but still don’t feel well, this episode will give you the clarity and validation you’ve been looking for.This is essential listening for anyone dealing with: Histamine intolerance Chronic inflammation Gut health issues (SIBO, candida, dysbiosis) Hormonal imbalances Unexplained symptoms despite normal blood tests 🎧 Subscribe to The Histamine Well Podcast for more expert insights on root-cause healing, inflammation, and complex chronic conditions.✨ Want more?
