I haven't checked the others, but in the first one they seem to have given people 400 IU Vitamin E, which is equivalent to 180mg synthetic Vitamin E or 12x the RDA for Vitamin E. And they did that for 7-12 years straight. Also, the increase in cancer risk doesn't seem that significant if I'm reading the results right.

I'm not a fan of multivitamins that go crazy over the RDA unless I know the RDA number is way too low to begin with (like in Vitamin D's case). It's also an especially bad idea to go crazy over RDA with fat-soluble vitamins, because those are the ones that are stored in your body for longer periods of time. At least the water-soluble ones come out when you pee, but I think there's some new evidence that even some of those is stored or at least it may not be a good idea to "mega-dose" on them.

Some vitamin E supplements have 1000 IUs. See my other comment in this thread.
