What are the Functions of Microbial Gases, Hydrogen, Methane, & Hydrogen Sulfide with Dr. Tom Fabian | Rational Wellness Podcast 480
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. 00:00 Show Intro 00:59 Why Gut Gases Matter 04:04 Microbiome Metabolites 05:52 Butyrate Deep Dive 09:07 Measuring SCFAs 13:20 Hydrogen and Breath Tests 19:12 Hydrogen Benefits 28:19 Methane and Motility 31:06 Sponsor Break 32:13 Methanogens Explained 35:24 Hydrogen Sulfide Science 50:59 Clinical Takeaways Dr. Tom Fabian has a PhD in molecular biology and who has spent many years researching the microbiome and translating the scientific literature into practical applications for functional medicine practitioners.

Environmental Toxins and Health with Dr. Joe Pizzorno | Rational Wellness Podcast 477
Environmental Toxins, Wildfire Smoke, and Practical Detox Strategies with Dr. Joe Pizzorno Dr. Ben Weitz hosts the Rational Wellness Podcast and interviews Dr. Joe Pizzorno on latest research about environmental toxins, emphasizing wildfire smoke risks, PM2.5 penetration, rapid body and brain distribution, and links to neurological, respiratory, and cardiovascular disease. Pizzorno argues toxins are a primary, solvable driver of chronic illness and that oxidized cholesterol reflects toxic exposure more than cholesterol itself. Practical protections include running high-MERV (≥12, ideally 16) HVAC filtration 24/7, avoiding incense, and supporting detox with glutathione (liposomal or via NAC), increased and diverse fiber to reduce toxin reabsorption, and saunas to sweat profusely (except PFAS "forever chemicals," which don't excrete via sweat). They discuss mercury release from forest fires, microplastics and gut binding, arsenic reduction from rice cooking, water filtration (carbon block, RO for arsenic), endocrine disruptors like bisphenols, and toxin assessment using GGTP, ALT, eGFR, and urinary 8-OHdG rather than challenge tests. 01:02 Meet Dr Joe Pizzorno 02:24 Wildfires and Toxic Exposure 05:21 PM2.5 and Systemic Damage 07:24 Cholesterol Oxidation and Toxins 09:35 Home Air Filtration Tips 11:25 Mercury From Forest Fires 13:15 Glutathione and NAC Basics 14:41 Binders and Fiber Strategy 17:26 Persistent vs Nonpersistent Toxins 19:21 Saunas and Forever Chemicals 21:47 Microplastics and Gut Binding 24:13 Post Fire Cleanup Safety 25:21 Arsenic in Water Rice Chicken 27:54 Whole House Water Filters 29:08 Chlorine Fluoride Tradeoffs 31:08 Plastic Bottles and Bisphenols 31:54 Endocrine Disruptors Explained 33:58 Phytoestrogens vs Xenoestrogens 35:49 Safer Drinkware and Cookware 36:37 Testing Toxins Smarter 39:49 Biomarkers GGTP ALT eGFR 44:37 Detox Nutrition and Glutathione 46:54 Toxins and Autoimmune Disease 48:22 Cure Versus Suppression 53:44 Final Thoughts and Outro Dr. Joe Pizzorno is one of the founders of the modern naturopathic medicine and also the Functional Medicine movement, founding president of Bastyr University, editor of the Textbook of Natural Medicine, and one of the world's leading authorities on environmental toxins and chronic disease.

Rational Wellness Podcast Episode 020: Bioidentical Hormones for Women with Dr. Jill Stocker
Rational Wellness Podcast Episode 020: Female Hormones with Dr. Jill Stocker Dr. Jill Stocker discusses the use of bioidentical estrogen and progesterone hormones to help women restore their youth and vigor and their "juiciness". I laid out the topic first by talking about how it was believed for decades that estrogen was protective for the heart, which is why women have a lower risk of heart attack than men until menopause and then their risk increases equal to men's. There was however, concern about the increased risk of breast and ovarian cancer. When the Women's Health Initiative study was published in 2002 it shook the field of women's hormone replacement therapy by demonstrating an increased risk of heart attack and stroke in women who took equine (from horses) estrogen and synthetic progestins (Premarin and PremPro). But these results do not necessarily apply to the use of bioidentical hormones, which are much safer. Dr. Jill Stocker can be reached at https://www.jillstocker.com/ or here: http://www.thebodywellusa.com/ Dr. Ben Weitz is available for Functional Nutrition consultations specializing in Functional Gastrointestinal Disorders like IBS/SIBO and Reflux and also Cardiometabolic Risk Factors like elevated lipids, high blood sugar, and high blood pressure.

How to Eat for Peak Athletic Performance | Dr. Philip Goglia | RWP #18
View the Show Notes For This Episode Dr. Philip Goglia explains to Dr. Ben Weitz how to improve athletic performance through nutrition. [If you enjoy this podcast, please give us a positive review on Itunes, so more people will find The Rational Wellness Podcast] Podcast Details Dr. Goglia explained that using the correct macronutrient food pattern that fits each person's metabolism is crucial. This can be determined via a questionnaire and by looking at a lipid profile. If you are efficient at burning fats and carbohydrates and you consume a vegan diet, it will not work very well. Some people are efficient at burning fats and proteins, some are efficient at burning carbs, and some are efficient at both. Dr. Goglia will often utilize a pretraining cocktail with athletes that includes D-Ribose, L-Glutamine, Taurine, Cinnamon, Calcium and Magnesium, and blackstrap mollases. We'll even add citrulline mallate to it. He mentions that when his athletes have an athletic event in the morning, he will have the athletes eat a "mash" in the evening that includes shredded wheat, apple sauce, almond butter and jam. They'll wake up with lots of energy. He may also have the athlete consume this "mash" several hours before an athletic event, such as a basketball game or an athletic event.

Polyendocrine Metabolic Ovarian Syndrome with Dr Felice Gersh | Rational Wellness Podcast 468
View the Show Notes For This Episode PCOS Renamed PMOS: Root Causes, Hormones, Metabolism, Labs, and Integrative Treatment with Dr. Felice Gersh Dr. Ben Weitz introduces an interview with OB-GYN and integrative physician Dr. Felice Gersh on PCOS, newly renamed polyendocrine metabolic ovarian syndrome (PMOS) per a May 12, 2026 Lancet announcement, meant to shift focus from "cysts" to hormonal and metabolic dysfunction. Gersh argues ovaries remain central, describing impaired aromatization leading to low estradiol, high LH-driven testosterone, and downstream effects including insulin resistance, inflammation, leaky gut, altered microbiome, sympathetic activation, elevated cortisol/DHEAS, obesity, mood disorders, sleep apnea, and autoimmune risk. They discuss legacy and practical issues with renaming, updated diagnostic criteria adding anti-Müllerian hormone in adults, and PMOS as a diagnosis of exclusion. Recommended evaluation includes total testosterone, DHEAS, SHBG, thyroid panel with antibodies, lipids including apoB, hsCRP, nutrients, ANA, prolactin, and select rule-outs (17-OHP, Cushing's, tumors). Treatment emphasizes lifestyle, plant-focused diet, time-restricted eating, exercise, supplements (myo-inositol, NAC, quercetin, melatonin, mitochondrial support), cautious pharmaceuticals (metformin/berberine, spironolactone), and cyclic bioidentical estradiol/progesterone; low-dose dexamethasone is noted for select adrenal-driven cases. 01:02 PCOS Renamed PMOS 04:51 Hormone Pathway Explained 09:04 Systemic Effects Cascade 13:15 Prevalence And Risks 17:29 Name Change Debate 18:28 Follicles And AMH 22:54 Inflammation And Immunity 26:17 Origins And Modern Triggers 31:40 Why Rebranding Falls Short 35:05 PCOS PMOS Searchability 35:48 Updated Diagnostic Criteria 37:52 Teen vs Adult Criteria 39:01 Key Lab Workup 44:07 High DHEAS Red Flags 45:00 Diagnosis of Exclusion 47:39 Lifestyle Treatment Plan 49:16 Diet and Fasting Strategies 53:45 Meds and Herbal Options 54:43 Mitochondria and Supplements 57:54 Inositol Ratio Debate 01:00:47 Hormones and Antiandrogens 01:04:03 Adrenal DHEAS Suppression Dr. Felice Gersh is a board certified obstetrician and gynecologist and she is also fellowship-trained in Integrative Medicine.

Bhojraj explains why conventional cardiology's LDL-centric, statin-heavy approach can miss key drivers of atherosclerosis, drawing from years treating repeat heart attacks. He reviews how plaques form through endothelial/glycocalyx injury, oxidized and small dense LDL, and immune activation leading to rupture and clotting. They discuss comprehensive lipid and cardiometabolic testing (ApoB, Lp(a), oxidized LDL, insulin, A1c, CRP, MPO, Lp-PLA2, homocysteine, uric acid, TMAO), insurance barriers, and a HEART framework (Hormones, Energy, Autonomic nervous system, Rest/Repair, Triggers).

Renna argues that 90% of aging outcomes still come from diet, exercise (including resistance training), sleep, and psychological perspective, with supplements and hormones as important supports. He explains why stem cells are often overhyped, why many donor cells die quickly, and describes Muse cells as a type that can survive longer, noting Florida's approval of umbilical cord cells for osteoarthritis and Lifespan's plans to offer Muse cells.

Dr. Kate Davis on Parasites, "Drainage," and Functional Strategies for Chronic Gut Symptoms Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Kate Davis, a chiropractor turned functional medicine practitioner specializing in gut health. Davis recounts developing severe constipation and bloating at 24, receiving limited GI options, getting relief from visceral/myofascial work, then later worsening symptoms after stress with brain fog and joint swelling. A functional medicine friend used a hair follicle test (Cell Wellbeing) that suggested parasites; Davis followed an individualized protocol (including CellCore products, herbs, binders, Mimosa pudica seed, and TUDCA) and passed numerous parasites with symptom resolution. In practice she treats constipation, bloating, and loose stools by prioritizing "drainage" (bowel movements, liver/gallbladder/lymph function), assessing via hair scans, symptoms, stool/toxin tests, and bloodwork, and using diet, fermented foods, lifestyle, vagus/vestibular exercises, and breathwork; she discusses binders, mold, leaky gut, and insulin resistance targets, and shares contact info and an Instagram consult offer. 00:00 Show Intro 01:03 Meet Dr Kate Davis 01:33 Her Gut Health Journey 04:21 Parasites And Testing 06:30 Detox Protocol Basics 07:44 Practice Focus And Cases 09:06 Testing Leaky Gut 12:22 Parasite Treatment Strategy 13:58 Drainage And Gallbladder 16:18 Apollo Wearable Sponsor 17:51 4R Framework And Detox 21:04 Diet Probiotics Lifestyle 24:24 Gut Brain Vagus Nerve 28:46 Underrated And Overrated 32:04 Breathwork And Wrap Up 34:52 Podcast Outro Dr. Kate Davis is a Doctor of Chiropractic and she also has a BS in Microbiology & Cell Science and also in Psychology.
