I don't know what amount boytos takes, but here is a website with recommendations -

Also our vitamins & supplements forum is pretty good for info like this too.

there is the natural vit E as well as the synthetic E - that might be another thing to consider with supplements - quality of the ingredient, absorbability etc.

I used to read about all this vitamins/supplements stuff ages ago, but my brain can't multi task like it used to... I've forgotten much of it and new findings have come into play also.
