Well, I don't know if it's the real thing or not, but since having my ovarian tumor removed I haven't had any IBS-D symptoms. Have had C but don't know if it's IBS or just post surgery C. Anyway I have been drinking a glass of this plum smart juice before I go to bed, and I have been so regular every day since. It has a lot of fiber in it so it is an idea for IBS-C sufferers.
