I took 2 mg copper supplement to reverse grey hair and I feel nauseous. Google search said its a sign of too much copper or lack or zinc so too much copper or body can't handle copper because of some disorder like Wilson's Disease. What can I do to get copper to turn hair color back but not get sick? I didn't realize too much copper can hurt the liver. I didn't take much so maybe I need zinc then I can take the copper again? Its some good brand chelated copper. If my sick is not due to a zinc deficiency can I make liver stronger somehow? I must have copper deficiency because of all grey hair.
