Yeah I've used ozone for over 10 years now. //www.curezone.org/forums/fm.asp?i=333909#i
My wife had cancer twice and we drank ozonated water right after eating and it still cured the cancer. It might reduce nutritional intake, but not enough to worry about it, in my opinion. Plus we didn't have the medical grade generator then either. That's why my motto is, Any ozone is better than no ozone.

I didn't read the article, but vitamin c tricks the cancer into thinking its Sugar and it sucks up the vitamin c, which kills it from the inside out. Then ozone kills it from the outside in. A double whammy.
