I had a reaction to selenium as well and flipped out one night after taking it and didn't know what to do with myself, I was crying more and more shaky. The reaction didn't last long term, but again it was unnerving. Selenium really seems to be something that can be kind of dodgy sometimes. That's why Andy says you can take it or leave it pretty much. However 200 mcg is ALOT to start if you are really toxic and may have been what pushed you over the edge, plus what kind of selenium can also make the difference.

cmlyon, you haven't said what kind of selenium it is......? I'd be curious to know. That may make the difference too. When I flipped out, I was taking selenite. Yet it had done great for me in certain times in the past and seemed honestly to help me get a bit less toxic over time. Either that or it just "felt" that way. But I believe it did aid my body to eliminate "some" mercury because it increased the mercury rashes I was getting when I heated up. I had a terrible time with that. It was caused by a DMPS IV injection, which had pulled so much metals into accessible areas, that I was beside myself with what happened. I could not cope with it and had rashes for years whenever I heated up (mercury rises with heat apparently). It was a bizzare thing and was so extensive it would cover me from head to toe. However, that's another way I managed to eliminate metals. DMSA was also very helpful to properly chelate and sped things up I believe.

I doubt the bit of rice flour in the capsules will make any significant difference to be honest. It's hard to avoid these things, if it's not rice flour, it'll be something else! I don't recall being affected by that. But I was when I got into eating rice itself!
