That is to be expected in someone who is mercury toxic, especially if they aren't taking a selenium supplement. If you take 200 mcg a day of selenium it might really help. It is a pity that large doses of selenium are toxic, and that it is not advised to take more than 200 mcg a day of selenium supplements.
" I don't want to take too much for a start and if I do take a very large dose it will only be for a little while, to see if it can kick start my thyroid."
