Copper
Among its many functions, copper aids in the formation of bone, hemoglobin and red blood cells and works in balance with zinc and vitamin C to form elastin, an important skin protein.
It is involved in the healing process, energy production, hair and skin coloring, and taste sensitivity.
This mineral is also needed for healthy nerves and joints. One of the early signs of copper deficiency is osteoporosis.
Copper is essential for the formation of collagen, one of the fundamental proteins making up bones, skin and connective tissue.
Other possible signs of copper efficiency include anemia, baldness, diarrhea, general weakness, impaired respiratory function and skin sores.
A lack of copper can also lead to increased blood fat levels.
Excessive intake of copper can lead to toxicity, which has been associated with depression, irritability, nausea, and vomiting, nervousness and joint and muscle pain.
Ingesting a quantity as small as 10 milligrams usually causes nausea.
Sixty milligrams generally results in vomiting and just 3.5 grams (3,500 milligrams) can be fatal. Children can be affected at much smaller dosage levels.
