100mcgs should do it as long as you have thyrosine prsent. Anything more than 200mcgs every day can be toxic.
As an aside, selenium is lost during ejacualtion. (!)

It should be known that for PWA's that 200 is recommended. Alan.
Celica, thanks for bringing that up. As I understand it, there are also 2 forms of commercial Selenium, natural and synthetic(like Vit E for example). Nelson... which form does the brand you promote contain? What difference do you think it makes in the effectiveness? I've seen studies that claimed Nat Vit E has MUCH greater absorption rates that the DL form. Thats why I ask.
In some case I believe it makes a big difference, and it others it makes no difference at all. For example, acetyl forms of certian nutrients have been shown to be more bio-available than no acetyl. At one time chelated minerals were all the rage until they realized it didn't make much of a difference. Minerals that are asportate instead of citrate are slightly more absorbable, but the difference is probably a a matter of a few mgs -- hardly worth the difference.
As far as "natural" vitamins, I don't buy it. The molecular structure of something like Vitamin C is the same whether it comes from an orange or a laboratory. Of course, an orange has other co-factors, but that is irrelevant when it comes to vitamins because they still have to processed and broken down into their molecular structure. So it really doesn't matter where the nutrient comes from, if it's in a pill, it all winds up being a procesed nutrient in the end.
