Vitamin C & E supplements hamper endurance training

It was only a 54 person study, so not very large, but interesting results.

Interesting. I take C to increase absorption of iron from supplements I take for anemia, but that's it.

Though the very small sample size makes me question it a bit too much to make a change right now.

That's interesting. Those are pretty high doses of E and C. I take a women's multivitamin so I had to check the dosages--it has 60 mg of vitamin C and and 15 mg versus the study's 1000 mg of C and 235 mg vitamin E supplements.

It was also an Norwegian study so that might be part of the difference?  And if you take a straight Vit C supplement I wonder what the dosage is vs just the vit C in a daily multi?

You can definitely buy higher dose single vitamins (like 1000mg Vit C) in the US. I was just curious what my 'normal' vitamin intake was compared to their study drugs.
