If you are undergoing colon cleanse and is looking for colon cleansers that work you have to at least read all the reviews of all the brands and see for your self what brand will work for you. There are many websites that do reviews so it would be of big help if you go and visit such.
However, I would prefer to do it naturally if I have to do that. I know there are foods (fruits and vegetables) that will help you clean your colon and detoxify your body. But reminding you also that you it is best to consult your physician before starting any colon cleanse program.
