I tend to agree with those doctors about antioxidants squelching free radical activity in the body, but my belief takes it to an even higher level. I feel that a supply of high-quality and broader spectrum of antioxidants and co-factors are essential to have on board when doing any oxygen therapy. This has been my experience of 15 years with active forms of oxygen like ozone and H2O2. To me it makes sense to allow the oxygen to eliminate the dead, diseased and dying cells but antioxidants protect the living cells from free radical damage. Different tissues of the body require different antioxidants for protection, so limiting it to Vit C, E and A plus co-factors is like buying insurance for just the roof or the plumbing of the house and not the whole house.
my 2 cents worth
