Copper (a mineral) is a trace element and humans require a very small amount of it. Copper is the third most abundant trace mineral in the body, but it is often deficient in a person’s diet because food sources high in this mineral are not always eaten frequently. However, copper deficiency is rare and is most frequently seen in cases of severe anorexia, starvation, or rare kidney problems. The human body contains approximately 100-500mg of copper but its role is important, as it serves as a co-factor for enzymes involved in haemoglobin and collagen formation and is involved in incorporating iron into the structure of haemoglobin.

Copper works together with iron to make red blood cells and it is the major component of the outer coating of nerve fibres and collagen. Copper is involved in the maintenance of immunity and fertility, formation of melanin and the promotion of consistent pigmentation. It is believed to play a role in preventing high blood pressure, heart arrhythmia, oxidation of the cells and keeping cholesterol low. Copper is used by the body to manufacture numerous enzymes, many of which work as antioxidants
