This isn't really a pro-vitamin article but I thought some of you might find the research interesting anyway:
[quote]In the new study, Morrow and Roberts determined the optimum antioxidant dose of vitamin E using an assay they developed to measure compounds formed by oxidative stress processes, called F2-isoprostanes. This measure, said Roberts, “has been independently validated as the best measure of oxidative stress status in vivo.â€

Great post! Thank you. (I'd seen these numbers somewhere, but not the 16 weeks part).

What would be interesting is to run the same experiment, with high vitamin C intake. It is my own hypothesis that vitamin E is useful in we humans because it spares our usually very low level of vitamin C.

Additionally, with ascorbic acid being able to take radicals from Vitamin E allowing it to be used again, I would speculate that a little V-E would go further with copious amounts of V-C in your system.
