Hi, I am fairly new to this list. I am working on fixing my gut problems due to an exacerbation of some of my fatigue and travelling joint/tissue pain.. (Metametrix analysis showed overgrowth of prevocella and no detectable lactobacillus). I have been on Diflucan for several weeks, and probiotics but was supposed to be on some kind of prebiotic as well. I have never been able to tolerate psyllium and did try apple pectin but it created +++ gas. Magnesium is helping but I was curious about taking potato starch. Some posts say that it is recommended to restore your gut and well-being, but others say that if you have an autoimmune problem, which I may have, you should not use it. As well, I read that prevocella will bloom if you feed it resistant starch. I don't want to undo all the work I have been doing to restore the balance, but I am wondering if anyone has any suggestions for a good prebiotic that would achieve a similar function?
