I had some gut bacteria issues and I think I was helped recently by using oregano oil and/or allicine (extract from garlic). Used both for a week, before had 2x antibiotics for suspected SIBO. I also used VivoMaxx 450 probiotics and sodium butyrate for 3 days so maybe it was it. All of these combined are cheaper than single curation with antibiotics so worth giving a shot in case of issues.
