<<Disclaimer: Verify this information before applying it to your situation.>> Hi everyone, I have refractory sprue and I have been drinking Ensure to try and get some kind of nutrition. Has anyone ever experienced dark stool/diarrhea while taking this? I am also on Colazal for colitis. I am hoping that one of these things is causing the problem. Thanks!
