Hello, I'm new to the group and apologize if this issue has already been addressed, but I couldn't find in when I searched. I recently started taking Fosamax and it has triggered a bad case of IBS, which I have been successfully treating through diet and exercise for the past 40 years. Does anyone recommend probiotics and/or prebiotics, and, if so, is there a brand that you have found works best? I would appreciate any input you might share, and thank you in advance!
