I have been using this product on and off now for 4-5 years. It works. Very impressed with the results of the Robert Gray method. Any one serious about Intestinal Cleansing in a natural and holistic way that is also gentle on the body this try this product. The taste is not like candy, but even that I got used to after a couple of weeks (i.e. the bulking agent). The pills are no problem for they are just swallowed and they did not upset my stomach in any way, even at the higher doses. Of course, I would only suggest following the method as described.
