Copper is a mineral available in trace amounts throughout the body incorporated into organic complexes, such as enzymes involved in brain function and the circulatory System. It is also extremely important for the development of the long bones, like the femur. Copper deficiency results in thin bones that fracture easily. Copper is an oxidant, yet in the body it has an antioxidant function by being a co-factor in the enzyme superoxide dismutase (S.O.D.). This enzyme protects the cells from the damage caused by free radicals and peroxides.
Copper is also part of the protein, ceruloplasmin, found in the blood plasma. Ceruloplasmin regulates the level of certain hormones in the blood and is also required for the formation of red blood cells. Additionally, copper plays a part in energy production, melanin formation and fatty acid oxidation.
Copper deficiency increases the risk of heart and circulatory problems, especially if there is also a selenium deficiency. Copper deficiency can also contribute to anemia, bone diseases, nervous system disturbance and hair loss. In children, growth is inhibited and the bones may become brittle.
Dietary Sources: Oyster, lamb’s liver, crab, Brewer’s yeast, olives, hazelnuts, shrimps, cod, whole wheat bread, and peas.
Dosage: The RDA for copper is 0.9mg. The upper safe level for daily supplementation is 5mg.
Side Effects: High intake of copper is toxic. Copper should not be taken by people with Wilson’s disease, a genetic disorder of copper metabolism.

Some facts about copper
1. Copper ions in cysteine naturally inhibit/fight viruses and offer protection from chronic autoimmune diseases
2. Copper works in synergy with zinc to remove free radicals
3. Experimentally, rats require more copper to maintain normal immune and thymus function when they are fed fructose rather than starch.
4. Copper is essential to cardiovascular health and some heart medications affect copper metabolism.
5. Many Western diets are deficient in copper
6. Cholesterol levels in edible chicken can be lowered with increased copper supplementation
7. Copper is essential to red and white blood cell development
8. Ceruloplasmin is a protein that transports copper which is elevated during pregnancy and may account for the spontaneous suspension of rheumatoid arthritis during pregnancy
9. Copper deficiency is aggravated in a high fat diet
