...ROS are also implicated in many theories of aging and cellular damage, which is why cells have several systems to try to soak these things up. That’s exactly why people take antioxidants, vitamin C and vitamin E especially. So. . .what if you take those while you’re exercising?
A new paper in PNAS askes that exact question. About forty healthy young male volunteers took part in the study, which involved four weeks of identical exercise programs. Half of the volunteers were already in athletic training, and half weren’t. Both groups were then split again, and half of each cohort took 1000 mg/day of vitamin C and 400 IU/day vitamin E, while the other half took no antioxidants at all. So, we have the effects of exercise, plus and minus previous training, and plus and minus antioxidants.

Oh, darn. Well, that explains a lot. Clearly I’ve been wasting a lot of time. Need to stop taking Vitamin C and E.
What does it say, the stupid link times out for me and wont come up
They’re not gonna get me to give up my Vit C. I KNOW it’s benefits.
I don’t take C and E. I take a multi, though.
Cheers!
Oh, if it’s saying Vitamin C is bad that is a load of BS, the medical establishment keeps hammering away natural things that are good for you, especially suppliments, they want to regulate them all. How many again die of thier pharmasuitical drugs each year? Did you know they don’t want you to take Vitamin C during Chemo and.or Radiation as it protects cells so well it can negate their effects? Ya, right, thank you researchers but no thanks, I haven’t even read it but I know it’s BS out of hand.

Now, considering that most mammals produce their own ascorbic acid(Vitamin C), then perhaps exercise is a secondary mechanism, or even a coincidental mechanism for reduction of free radicals.
Our bodies evolved using the vitamins and minerals found in food, nothing else. From an evolutionary standpoint, it makes no sense at all to be loading up on vitamin supplements. This is definitely not a case of “if a little is good, a lot must be better.”
Either you have enough vitamins and minerals for the enzymes in your body to function, or you don’t. If you don’t, then you have a reason to take supplements (or, better yet, modify your diet); otherwise, it’s a waste of money, and a stress on your body (because you have to remove the excess vitamins and minerals, putting a stress on the liver and kidneys).
Has the author of this study worked for several major pharmaceutical companies?
Derek Lowe, an Arkansan by birth, got his BA from Hendrix College and his PhD in organic chemistry from Duke before spending time in Germany on a Humboldt Fellowship on his post-doc. He's worked for several major pharmaceutical companies since 1989 on drug discovery projects against schizophrenia, Alzheimer's, diabetes, osteoporosis and other diseases.
They didn’t give the subjects enough Ascorbic Acid. It should have been more like 4 grams a day (1 gram 4 times daily).

I do take a lot of vites (including mega-C), so I guess that means that exercise is bad for me. Oh, well...
We were not designed to live much past breeding age. Average lifespan of cavemen was probably 30 tops. As Durk Pearson once said, “If you wish to live unnaturally long and be unnaturally healthy, you have to do a few unnatural things”.
As for me, I have been taking unnatural antioxidants (BHT, BHA, and others) for 30 years. Based on what we see in lab rat experiments, I should have only aged about 20 years in that 30 year span. Most people guess my age to be 10 years less than it is.
In about 30 years I will know if my experiment worked. If I am still around, I will go cyberonic and change my legal name to Darth.
I thought that when I exercise, I should take vitamin x.
