I recently took Clostridium Butyricum (Miyarisan), and found I got some unpleasant effects that reminded me of when my M.E. was much worse (so think I will restart at a much lower dose and build up). I think this could indicate I still have a bad bacteria problem in my gut, but I want to make sure it's not just a bad reaction to Clostridium Butyricum (i.e. my body just finds it toxic). Would a healthy person with no bad bacteria overgrowth would get no bad effects from Miyarisan?
