What are the best supplements for SIBO (small intestinal bacterial overgrowth)?

Research and clinical practice suggest that herbal antimicrobials (berberine, oregano oil, allicin) may help address SIBO, with one study showing comparable efficacy to the antibiotic rifaximin. Partially hydrolyzed guar gum (PHGG) has shown benefit as a biofilm-disrupting agent and prokinetic support. After treatment, strain-specific probiotics like Lactobacillus rhamnosus GG may help prevent recurrence.

Can supplements alone manage SIBO?

Herbal antimicrobial protocols may be an alternative to antibiotic therapy for some SIBO patients, but comprehensive management typically requires identifying and addressing underlying causes such as impaired motility, structural abnormalities, or medication effects. A multi-pronged approach including dietary modifications (such as the elemental diet or low-FODMAP), prokinetic agents, and addressing root causes is generally most effective.

When should I see a doctor for SIBO symptoms?

See a doctor if you experience persistent bloating, abdominal discomfort, diarrhea, or malabsorption symptoms (unintended weight loss, nutritional deficiencies, fatty stools) that do not improve with dietary changes. SIBO requires proper diagnosis through lactulose or glucose breath testing. Recurrent SIBO after treatment also warrants medical evaluation to identify underlying causes and prevent ongoing damage.
