Actually the recommended selenium levels are falling now.
In the past 200mcg/day was considered okay. Today is more like 100mcg to be really safe. That is up to the user however.
Excess selenium is toxic, and also implicated in some Type II
diabetes. But the latter is only so-so in studies.
When you take a multiproduct vitamin, you risk getting too much of some things. Especially the minerals. But retinol Vit A may also be involved. It depends on the formula.
