An Integrative Approach to Parkinson's: Gut-Brain Axis, Toxins, Pro21 Diet, Testing & Key Supplements | Dr. Karin Duncan
Dr. Ben Weitz introduces a Rational Wellness Podcast episode on Parkinson's disease with naturopathic physician Dr. Karin Duncan, who is launching the Integrative Neurology Wellness Center in Hayden, Idaho in partnership with the Northwest Parkinson's Foundation to provide accessible integrative care. They discuss Parkinson's as more than dopamine deficiency, emphasizing toxins, inflammation, mitochondrial dysfunction, oxidative stress, and the gut-brain axis, with increasing young-onset cases. Duncan explains clinical diagnosis, limits of DaTscan, and her reliance on the CND/Syn-One skin biopsy for alpha-synuclein. They cover prodromal symptoms (constipation, loss of smell, REM sleep behavior disorder), alpha-synuclein and Lewy bodies, and her evaluation approach including nutrient and inflammatory labs, omega-3/6 targets, iron, thyroid/hormones, microbiome testing, and caution with detox. They review ProPD symptom tracking, Pro21 diet (avoid dairy, beef/pork/chicken, fried/refined/canned foods), exercise, glutathione, DHA, low-dose lithium, vitamin D/K2, LDN, and careful use of methylene blue, plus community and mental health support.
Dr. Laura Mischley's Pro 21 diet was published: Beyond MIND and Mediterranean Diets: Designing a Diet to Optimize Parkinson's Disease Outcomes.

The HRT Questions Most Women Never Get Answered with Karen Martel | Rational Wellness Podcast 481
Perimenopause to Menopause: Testing, Progesterone First, and Evidence-Informed HRT with Karen Martell
Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews hormone specialist Karen Martell about perimenopause and menopause, emphasizing that midlife hormonal shifts affect metabolism, sleep, mood, cognition, bone and cardiovascular health. Martell says perimenopause can begin in the mid-30s, often with declining progesterone from less frequent ovulation, leading to heavy periods, insomnia, anxiety, and perceived "estrogen dominance," while estrogen later becomes erratic and then declines toward menopause around age 51. She critiques common responses like birth control, hysterectomy, and symptom-only medications, and recommends combining bloodwork with saliva or urine metabolite testing (e.g., DUTCH) when cycling. For HRT, she prefers transdermal estradiol over oral estrogen, discusses progesterone delivery options and sensitivities to oral metabolites, addresses testosterone (often compounded; injectable preferred), and notes roles for DHEA and pregnenolone. She also covers vaginal therapies, dosing based on both symptoms and protective lab ranges, and cautious later-life initiation.

What are the Functions of Microbial Gases, Hydrogen, Methane, & Hydrogen Sulfide with Dr. Tom Fabian | Rational Wellness Podcast 480
Gut Microbial Gases Beyond SIBO: Hydrogen, Methane, and Hydrogen Sulfide as Signaling Metabolites
Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Tom Fabian, PhD, to discuss gut microbial gases beyond the usual SIBO framing. They explain that hydrogen, methane, and hydrogen sulfide are normal microbial metabolites with potential signaling roles, alongside key microbiome products like short-chain fatty acids (especially butyrate), which fuels colon cells, supports tight junctions, regulatory T cells, and helps maintain an anaerobic colon environment. Fabian notes metabolomics (e.g., GI-MAP stool add-ons) can provide functional insight beyond which microbes are present, highlighting butyrate producers such as Faecalibacterium and Roseburia. They review controversies in breath testing interpretation, discuss methane biology and debated links to constipation, and emphasize emerging research that hydrogen sulfide is widely produced (often from cysteine metabolism), supports colon mitochondria and anaerobiosis, may relate to stress responses and longevity, and that excessive sulfur restriction may be misguided; fiber and polyphenols may mitigate protein-driven hydrogen sulfide.

Galectin-3, Modified Citrus Pectin, and Therapeutic Apheresis: Emerging Applications in Sepsis, Cancer, and Chronic Inflammation
 
Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews returning guest Dr. Isaac Eliaz about galectin-3 as an upstream driver of inflammation and fibrosis implicated in chronic degenerative disease, autoimmunity, cancer progression, and acute sepsis. Eliaz explains modified citrus pectin (PectaSol) as a researched galectin-3 inhibitor, discusses dosing ranges, and describes its clinical relevance across inflammation, cardiovascular risk, microbiome effects, and cancer (including prostate cancer trials). The conversation focuses on therapeutic apheresis and plasma exchange, contrasting nonselective plasma exchange with selective approaches such as LDL apheresis and Eliaz's developing Xgal-3 filter designed to remove circulating galectin-3. He cites porcine sepsis data, an FDA breakthrough designation, upcoming sepsis trials, and potential to enhance cancer immunotherapy, while warning about hype, safety, training, and misuse in integrative settings.

IBS and SIBO Breath Testing with FoodMarble: Real-Time Hydrogen and Methane Monitoring


Dr. Ben Weitz introduces the Rational Wellness Podcast episode on IBS and SIBO with guests Angus Short, PhD (CEO/co-founder) and Claire Short, PhD (chief clinical officer) of FoodMarble, creators of the handheld AIRE breath analyzer that measures hydrogen and methane in real time to track fermentation patterns at home. Inspired by Angus's wife's unresolved IBS symptoms and restrictive dieting, the device evolved from early prototypes into a validated product, including published research with Johns Hopkins showing equivalence to a leading mail-in breath test kit. They discuss following North American Consensus SIBO protocols (prep diet, fasting, lactulose or glucose, readings every 15 minutes for two hours with customizable options), additional at-home FODMAP intolerance tests, symptom/diet/stool tracking, and personalization. They note ongoing development of hydrogen sulfide measurement, factors affecting readings, and how monitoring can guide diet, supplements, and treatment choices.
