Copper is an essential trace mineral necessary for survival. It is found in all body tissues and plays a role in the synthesis of red blood cells and maintaining nerve cells and the immune system.
It also helps the body form collagen and absorb iron, and plays a role in energy production.
Most copper in the body is found in the liver, brain, heart, kidneys, and skeletal muscle.
Both too much and too little copper can affect how the brain works. Impairments have been linked to Menkes, Wilson's, and Alzheimer's disease.
Deficiency is rare, but it can lead to cardiovascular disease and other problems.
