Fluoride and you ?

[Kenzo]

Watch the selenium, you don't want to get too much in one day ... about 500 mcg IIRC.

I take it for a thyroid condition.

One thing, it will boost one's metabolism.  If one is looking to lose weight, try 200 mcg a day for a month.

Food:  Brazil nuts have varying amounts of selenium, but sometimes a single nut has a huge dose, so watch consumption of those.

Yeeh agree too much is not good either .  I think 200-300 mcg is usually enough .

There could be areas /places where food gives enough selenium .
