Would taking peppermint tablets give me an inaccurate result in the small intestinal bacterial overgrowth (SIBO) Test?

Peppermint could potentially affect your SIBO test results.

Peppermint can sometimes affect SIBO test results. This depends on the dosage and how long you've been taking it, so to be safe, avoid it for four weeks before the test.

This is because although peppermint isn't usually used as an antimicrobial, it has antimicrobial properties and has been shown in research to lower levels of certain types of bacteria.

If you take peppermint tablets regularly because they help your symptoms, don't worry. You can keep taking them, just let customer services know and they'll ask your practitioner to take that into account when they interpret your results.
