No one here is disputing the fact that free radicals are an essential part of the bigger biological picture. Take for instance one of the most currently popular bodybuilding supplements, nitric oxide (NO), which is in fact a free radical, one of the most essential free radicals of all known to man. It’s not a vitamin nor a mineral, not even a polyphenol no; it’s simply a biological gas. And what a gas it is! Although it’s a free radical, its presence or manufacturing is one of the most critically essential of all for maintaining our health. So as you can see, I at least, am in no dispute with anyone when it comes to the vital role free radicals have to play in the larger scheme of things.
The problem however is this: the environment we find ourselves living in today is causing an overwhelming of free radicals. In other words, the balance is shifting in favour of free radicals and disease causing compounds. Even breathing has become dangerous and in need of some counter measure.
By the way, an antioxidant like vitamin C or E for example can themselves become free radicals when their job of being an antioxidant is done. Hence, I put up the antioxidant “players” that work to recycle an antioxidant after completing its initial task.
Finally, as I've already alluded to in my previous post re the quantity of the pre and post vitamins. The last study you've put up talks of 1000mg of vitamin C. What I was talking about based on the book I've mentioned in my earlier post (which has prompted your initial response to me) was a mere 30-120 mg of vitamin C, and 20-60IU of vitamin E. That's a far cry from 1000mg of vitamin C and 400IU of vitamin E.
So although I was recommending the taking of vitamin C & E pre and post workouts, the quantity of these were not so overwhelming as to negatively affect any insulin response, but enough to exert their anti-oxidant power in time of need.
It's unfortunate that you've chosen to ignore my PS.
Fadi.
