I wish I had something positive to say, but unfortunately this has come up a lot in the past and we've looked into it without favorable findings.
According to some of the most reputable medical experts (Katz, Oz, etc) our colons or other body parts don't accumulate a buildup of toxins that can be removed by a detox. They state basically that it's a scam by various supplement manufacturers to sell unnecessary and potentially dangerous products. I've yet to find a hospital, university, or other reputable authority recommend products like that. The ads for them often quote various studies, but it seems that those studies don't really exist. Even testimonials are manufactured. What the real experts tell us is that our bodies are naturally cleansing and do a very good job of it. They recommend drinking 8 glasses of water and consuming at least 25 grams of fiber daily to keep our bowels moving everything out, and nothing is left behind. Occasionally a person will have a medical problem that requires physician assistance, but products like this are not recommended.
This particular product, Dual Action Cleanse, has a bad reputation. You can read more about it at http://www.infomercialwatch.org/repo...alaction.shtml
I hope that helps
