I am sorry if this is a redundant question, but I've read so much it's all starting to blur. DS 10 has been on antibiotics for almost a full year since initial PANDAS diagnosis. We're in a fairly good place although not completely healed (80%?). He takes prophylactic Keflex twice daily, omega 3s and an over the counter probiotic, along with CBT biweekly. I'm trying to figure out which probiotic would be best for him (current one is almost gone). It appears ProGut and Florastor pop up quite a bit in the PANDAS blogs, literature, etc. Does anyone have an opinion? Should they both be taken together or only one? I feel a little lost and feel this is a very important piece of his healing. Any help would be appreciated. Thanks!
