Honestly I think most of them are a load of crap, except for one. My Uncle did the one by Dr. Natura, called Colonix, and he said he was stunned that it actually gets visible stuff out. He said it was like someone had taken a bottle brush, run it through his intestines (it wasn't painful BTW) and pulled out everything clogging up the gut. It takes much more than a day though, to do all that at once could be bad so he did it for three months and feels fantastic, lost 10 lbs too. Most of the cleansers out there are liquid and people say they can "feel" it working, with this one you can literally see the dead lining of the intestines etc. in your stool
. It has won a bunch of awards so it isn't just a song and dance. They are a good company, they didn't try and get my uncle with "free promotions" and then automatic billing you every month. Go poke around the website, especially the testimonials and picture gallery, if you can stomach it
. I want to do it but alas I am but a poor college student who hasn't found a summer job yet so cash is tight.
