Copper is a trace mineral that is important for the formation of collagen, hemoglobin, and certain enzymes. Both high and low levels of copper can cause health problems.
Histidine is involved in copper absorption in the intestines. Altered histidine levels may impact copper uptake and status.

Methionine interacts with copper in the methionine cycle and is involved in copper regulation. Methionine changes can influence copper status.
