People eliminate parasites without ANY type of bowel cleanser or magnesium though.
I realize it has the added element of oxygen, but to me, that's not enough to justify it's exorbitant cost (and the fact that I have yet to read of anyone sustaining a lasting weight loss when using it for bowel cleansing).
EVERYtime I do a fiber cleanse (I use Schulzes IF#2) and see mucoid plaque, I ALWAYS have a weight loss that stays off. That proves that SOMETHING came out of my body and stayed out of my body. And since I actually see and know what comes out, I know my cleanses are being effective.
