Thank you for your question! Atrantil works to get rid of the bacteria in the small bowel. By taking a prebiotic, you are nourishing the bacteria so that they flourish in the small bowel instead of going back to the colon where they belong. Once Atrantil has had a chance to work and the small bowel is returned back to a sterile environment and the bacteria are back in the colon where they belong, you can add back in the prebiotics. However, if you do chose to take them while on Atrantil, just know it will take longer to see results. We hope this helps clarify, please let us know if we can be of further assistance.
Thank you and best wishes,
