Episode #214: Super Gut: Part 2 with Dr. William Davis, MD
In a Nutshell
Dr. William Davis explains SIBO/IMO as microbial overgrowths (e.g., Enterobacteriaceae, methanogens) driving constipation, endotoxemia, neurodegeneration (Parkinson's, Alzheimer's), autism behaviors, and more; eradicate with antimicrobials (zyxicin/neomycin, herbals like Candibactin) if severe, then restore via Super Gut yogurts (*L. reuteri*, *L. gasseri*, *B. coagulans/suis*) that deliver 300 billion CFUs/half-cup, produce bacteriocins, normalize breath tests in ~90%, and yield benefits like smoother skin, muscle gain, oxytocin boost, and waist reduction. Address upstream causes (wheat/grains, magnesium deficiency, PPIs, antibiotics) with grain-free diet, nutrients (Mg, D, omega-3, iodine), prebiotics/polyphenols, and avoid chronic low-FODMAP (harms diversity). Make yogurts via 36-hour fermentation of half-and-half + sterile inulin/starters at body temp; start low for SIBO-sensitive (1-2 tbsp), manage Herx reactions with charcoal, continue lifelong for transient benefits—no monoculture risk. H. pylori often net harmful (eradicate via vitamin C + black seed oil); test SIBO with Aire device + inulin; yogurts safe post-fungals/SIFO for most, transforming gut health beyond antibiotics.

Episode 214 of Better Health Guy Blogcasts with Dr. William Davis on Super Gut (Part 2). Part 1 in episode 213 covered microbiome, beneficial organisms, prebiotics, polyphenols, and mucus layer. Part 2 covers SIBO, IMO, and creating Super Gut yogurts.
SIBO is an umbrella term; methane-dominant SIBO now called IMO (intestinal methanogen overgrowth). Question if Super Gut program yogurts apply to hydrogen, methane, and hydrogen sulfide types.
Dr. Davis: Evolving concept. Hunter-gatherer populations often have more methanogens without constipation. Problem may be context, not overgrowth per se. Methanogens in modern people cause constipation and other issues.
Ways to eradicate/reduce methanogens: zyxicin with neomycin, Candibactin-AR herbal antibiotics. Suggestion: No rush; do basics—fermented foods, L. reuteri, L. gasseri, S. boulardii—let GI tract heal. Methanogen issue may self-correct (anecdotal).
SIBO organisms often in Enterobacteriaceae family (Proteobacteria): fecal microbes like E. coli, Proteus, Morganella morganii, Enterobacter, Citrobacter—very toxic.
Off-the-shelf probiotics won't resolve dominance. Use microbes that colonize small intestine/colon and produce bacteriocins killing those species. With Aire device, ~90% normalize hydrogen breath test.
