Evidence-Based Stack
Gut Health Stack
Four evidence-backed supplements for microbiome support, regularity, and gut-barrier integrity — not another kombucha fad.
Gut-health marketing is cluttered with low-dose probiotic blends and proprietary gimmicks. What the research actually supports is a smaller, more targeted stack: a fermentable prebiotic fiber to feed beneficial bacteria, a bulking fiber for regularity and cholesterol, a targeted amino acid for mucosal repair, and a butyrate source (or precursor) to directly feed colonocytes. This stack covers the three pillars of gut health — microbiome composition, motility, and barrier function — without betting on any single probiotic strain that may or may not colonize your particular gut.
What's in it
Bulking soluble fiber — improves regularity, binds bile acids (lowers cholesterol), and feeds bacteria slowly down the colon.
Dose: 5–10 g/day with water, split across meals. Ramp up over 2 weeks to avoid bloat.
Full Psyllium Husk profile →Fermentable prebiotic — selectively feeds Bifidobacteria and Lactobacillus populations.
Dose: 2–5 g/day, ramp up slowly. Higher doses cause gas in sensitive guts.
Full Inulin profile →Primary fuel for enterocytes. Supports mucosal repair in leaky-gut profiles and post-antibiotic recovery.
Dose: 5–10 g/day on empty stomach, split. 4–8 week course typical.
Full L-Glutamine profile →Short-chain fatty acid directly fuels colonocytes and has anti-inflammatory effects in the colon. Supplements supply it when fiber fermentation doesn't.
Dose: 150–600 mg/day of butyrate salt (sodium/calcium/magnesium butyrate).
Full Butyrate (Tributyrin/Sodium Butyrate) profile →How to take it
Start with psyllium + inulin at low doses for 2–3 weeks to let your gut bacteria adapt (expect some gas; that's fermentation doing its job). Add L-glutamine if you have active gut issues (IBS, post-antibiotic, gastritis, recovering from illness). Butyrate is the niche add — skip unless you have a specific colon-health indication.
Cautions
Psyllium can reduce absorption of medications; separate by 2 hours. Inulin aggravates IBS-FODMAP sensitivity in some users — start very low. L-glutamine is contraindicated in advanced liver or kidney disease. Stop adding new supplements if symptoms worsen and reintroduce one at a time.
