This supplement acts like a chimney cleaner that removes all the old dirt. That is the job it does in the colon, to remove all that old toxins that can lead to major problems in the future. I used it and my father too, both of us experiment more energy gain after taking this supplement entirely. The feel of sickness has gone and the bowel activity went to regular ones. I was so concern about the gastrointestinal health that I was searching for something good and cheap; I found both in this product. Colon Tone contains OxyGen, this is a unique compound that binds the molecules of ozone and oxygen in a crystal lattice matrix made from three compounds, vitamin C, magnesium, and bioflavonoids. This combination enables a natural detoxification that lead to a healthy gastrointestinal system. This was my unique goal with this supplement, to be healthy, a good gastrointestinal health is important in the prevention of cancer. A great deal I got here, that prevent me to go to my doctor for many years.
