Oxy Cleanse: Free Radicals?

Shelly, you may have, in part, answered a question I've had for some time now.

I always thought (perhaps naively?) that introducing oxygen into the body in large doses (as with the oxy cleanse products) would predispose the body to free radical damage. In fact, one oxy cleanse product I've used recommended taking an anti-oxidant (alpha lipoic acid) within 1 hour of taking the oxygen to counter-act the free radicals released in the body.

Is this why you suggested that super-green products provide a better, safer source of oxygen, at least for the long term?
