If you do a search, you can find many detox issues discussed previously. There are many forms of detox including eating fruits and vegetables only for a period of time, drinking only juice for a period of time, drinking only a sugary drink for a period of time or some combination of the above. There are also detox teas but I've never seen detox pills (or paid attention to them) which this appears to be. From the ingredients, it shares some ingredients with normal diet pills as well as laxatives. If you have digestive issues, I'm not sure taking laxatives is the best thing for you.
Personally, I think if you want to detox, you may do better with doing one that is based on real food rather than a pill.
You can't out-exercise poor eating habits.
