Ozone

Molecular hydrogen can cause the body to make its own internal antioxins. It doesn't do it if there's no oxidativ stress. So you could give it before, and it wouldn't make these anti oxin molecules until after the ozone was administer. But i think there is a potential downside for the ozone. You can overdo it and too much oxidie of stress. The hydrogen would be really affective. I'm one of my favorite supplementsd and i love ozone.
