My hair tests from 2004-2005 showed I was copper toxic too,
but managed to bring the copper right down with intense supplements &diet,avoiding lots of foods I love.
But now I just eat them when I feel like it.Maybe my copper is gone back up ,but I have no job &no money @the moment to get more tests done.If I could I would get frquent tests &be so interesting to see the levels change as you detox &also show all the sceptics.
According to Andrew Cutler the symptoms of mercury &copper toxicity almost identical.
I also suspect the fillings as a cause of the high copper since I've learned there are higher levels of copper in the amalgams of the last decade or so.

Anyway pumpkin seeds are good instead of nuts,they high in zinc, the enemy of copper.
