Chronic bloating is a pattern to diagnose, not a label to bury under probiotics.Stack-kit editorial
The useful answer depends on the cause: food intolerance, constipation, dysbiosis, IBS-like spasm, or SIBO. If you suspect SIBO, see a GI clinician for breath testing; first-line medical treatment often involves rifaximin, not a supplement pretending to be one.
First, rule out the serious stuff
Most bloating is benign. Some is not. Unintentional weight loss, blood or black stool, iron-deficiency anemia, night-waking symptoms, a bowel-habit change lasting more than a few weeks, family history of colorectal cancer, IBD, or celiac disease, or bloating that is constant and progressive belongs with a doctor.
Before a low-FODMAP diet or a supplement stack, rule out celiac disease while you are still eating gluten. The tissue transglutaminase IgA plus total IgA blood test can be invalidated if you go gluten-free first. If symptoms are significant, ask about a hydrogen/methane breath test. SIBO is not a vibe; it is a clinical diagnosis.
Then map the pattern. Meal-triggered gas points toward fermentable carbohydrates or enzymes. Distension with infrequent stool points toward constipation mechanics. Constant grazing can suppress the migrating motor complex. Fast eating, carbonation, gum, and straws can add swallowed air that no antimicrobial supplement will fix.
What actually helps
Enteric-coated peppermint oil is the first symptom tool. The source dose is 180-225 mg, 2-3 times daily, 30-60 minutes before meals. Cash, Epstein, and Shah 2016 studied a sustained-release enteric peppermint-oil formulation in IBS adults and found Total IBS Symptom Score fell 40% vs 24.3% on placebo, with abdominal pain and bloating improving. The caveat is clean: IBS is not breath-test-confirmed SIBO.
PHGG is the fiber option that earns a slot because it ferments slowly and distally. Start around 3 g/day, then titrate toward 5-6 g/day. Niv et al. 2016 found 6 g/day improved bloating score in IBS patients versus placebo. If every fermentable fiber worsens your symptoms, treat the suspected overgrowth first.
Berberine is the high-interaction herbal antimicrobial layer: 500 mg 2-3 times daily with meals for a 4-week course. Chedid et al. 2014 tested a multi-component herbal therapy that included berberine in breath-test-positive SIBO, but it does not prove berberine alone equals rifaximin. Treat it as a clinician-discussed adjunct or alternative inside a diagnostic plan.
Saccharomyces boulardii is the probiotic that makes sense when bacterial probiotics may not. It is a yeast, so it does not add to the small-intestinal bacterial load. The source positions it as a tolerable, SIBO-appropriate probiotic layer, not a direct bloating cure.
Alpha-galactosidase is for bean, lentil, soy, and cruciferous-vegetable gas. Take 300-1200 GalU with the first bites of trigger meals. If the product lists milligrams instead of activity units, it is not giving you the dosing number that matters.
When to skip
Skip peppermint oil with significant GERD, hiatal hernia, gallstones, pregnancy, or persistent burning. Skip berberine in pregnancy, breastfeeding, cyclosporine use, insulin or sulfonylurea use without prescriber input, and narrow-window CYP3A4 or P-gp drugs. Skip PHGG during a severe SIBO flare if it predictably worsens gas. Skip S. boulardii if immunocompromised, critically ill, or with a central venous catheter.
Evidence notes
- Cash, Epstein, and Shah 2016, Digestive Diseases and Sciences: enteric peppermint oil improved IBS symptom scores versus placebo over 4 weeks.
- Niv et al. 2016, Nutrition & Metabolism: PHGG at 6 g/day improved bloating score versus placebo in IBS patients.
- Chedid et al. 2014, Global Advances in Health and Medicine: multi-component herbal therapy including berberine normalized breath tests in some SIBO patients, with major design caveats.

FAQ
Do I need a SIBO breath test?
If symptoms are significant, persistent, or recurrent, yes. SIBO is a clinical diagnosis, and methane-positive cases are handled differently from hydrogen-dominant cases.
What is the best first supplement for bloating?
Enteric-coated peppermint oil is the cleanest first buy for IBS-like bloating, gas, and pain: 180-225 mg before meals for about 4 weeks, unless reflux or gallbladder issues make it a poor fit.
Should I take a high-CFU probiotic for bloating?
Not if SIBO is suspected. Broad bacterial probiotics can worsen gas by adding bacteria to the wrong place; the source protocol prefers Saccharomyces boulardii when a probiotic layer is appropriate.
