I can, from own experience, say that copper toxicity does indeed exist.
I have followed a copper lowering supplement program and gradually gotten better.
EVERYTHING I have read about copper toxicity fits right in with my disease history.
Just so I understand you correctly, are you saying that bio-available copper toxicity does NOT exist, but that bio-Unavailable copper toxicity DOES exist?
How would one go about correcting a situation with bio-unavailable copper if not through supplementation?
