Supplements That May Aggravate SIBO

---

Various supplements can worsen SIBO symptoms due to their carbohydrate content and ability to be fermented into symptom-causing gas by bacteria. This includes some notable digestive supplements like fiber, prebiotics and leaky gut healing agents. When a person with digestive symptoms worsens on these types of supplements, it can raise suspicion of SIBO, and reducing or eliminating these may help lessen symptoms.

Symptom reactions to carbohydrates vary greatly among SIBO patients, thus the supplements below may or may not trigger symptoms in a given individual. Dose often makes a difference - smaller amounts may be tolerated while larger amounts might not be.

Experimentation is needed to ascertain tolerance. Typically, suspected supplements are stopped for several days to a week, then restarted, while observing symptoms. Many choose to restart with a small amount (1/8 to 1/4 the dose) and increase slowly, others prefer to start with the full dose and stop if symptoms are aggravated. When starting fiber, beginning with a low dose and increasing slowly is advised. 

Consult your practitioner before discontinuing prescribed supplements. See full disclaimer below.
