They are basing it on hair tests and dmps testing.
So how do I reduce the copper levels? What herbs/foods are high in copper?
Hair testing is not even close to being accurate. Even copper leaching from your pipes could cause a high copper reading in the hair.
Not that familiar with dmps testing. But I would be careful about trying to reduce copper without making sure it is high. And I would would have serum copper checked for levels. If it is high then increasing zinc intake will lower copper levels.
Liver and shellfish are very high in copper. Others high in copper include sesame seeds, sunflower seeds and cocoa.
