It's so funny that you would post this now, Cherie - I just asked my doctor about it myself. Here's what he told me: he doesn't believe there's a need for it at all, but said that if you're someone that only has a BM once a week or so that you might benefit from it. However, regulating the amount of fiber in your diet (like taking a supplement if need be) will do the exact same thing. He doesn't feel that it would harm you, but that it would be a waste of money. He also informed me that there has been no formal study done on this to find out just how beneficial it is - if at all.
I told him about the web sites that I had seen where these people actually sent in pictures of their "results" (as they called them) and he said of course it would look like that! The enzymes in your body continue to work to break everything down, but since they have you fast and drink this solution, there is no bulk from food to come out in your BM, thus the nastiness that you see in your toilet.
I was glad that I asked him about it and got a real medical opinion of it. After talking with him, I decided not to waste my money on it after all. Good luck to you with this. I hope you find the information you need to make the right decision for yourself. Happy Holidays!
