Probiotics & Prebiotics for SIBO

Probiotics and prebiotics for SIBO are not one-size-fits-all — the right choice depends on which organism, which fiber, and which phase of treatment you're in. This guide breaks it down strain by strain: spore-based probiotics, targeted strains like L. reuteri, gentler prebiotic fibers like PHGG, and the ones worth using with caution — plus a clear timeline for what's typically used during active treatment versus the rebuild phase after.
