I just can’t believe it and so badly hope I don’t jinx it by talking about it, lol but prebiotin is the best thing to happen to me ever!! I am 80 years young and have had IBS since about age 12. As my husband used to say, “you know where every bathroom is” and truly so. I had begun to think there was something really wrong with my gut but holy cow it’s so much better it’s unbelievable! I only wish I had found you years ago, I could have been “normal”! My gut is so much more “quiet” now. Sorry to rave on and on but just want to thank you for helping me.

I am a 76 year-old male who thought he had a sensible diet, but my diverticulosis was turning into diverticulitis too often. So I started using Prebiotin. Ever since then I have not had an attack of diverticulitis, for which I am forever grateful.

I want to thank you for teaching me all about the Prebiotin fiber. Since I have started, my digestive system has been so much more regular than it has been in years. I have had no constipation, which was always a problem for me before, and now my weight is getting better as I am not as hungry as I used to be. Thank you so much!
