I'm looking to do a bowel/colon cleanse and I'm looking at different bowel/colon cleansing products/companies but I can't decide which one(s) are the most effective and work the best. I've checked a lot of these products on the internet and at health food stores but some if not most do provide customer's testimonials. I'm just wondering how real and/or accurate are these so-called testimonials? Can anyone personally recommend any good products/companies? I would greatly appreciate any feedback or help.
