Copper is the third most abundant essential trace mineral, after iron & zinc. The highest concentrations of copper are found in the brain and liver, but there are also appreciable amounts in skeletal muscle, the skeleton, skin, and bone marrow.

Functions of Copper:

A component of cytochrome oxidase; therefore involved in cellular energy production, A component of superoxide dismutase; therefore acts as an antioxidant against free radical damage, Involved in the synthesis of several neuroactive substances-for example, norepinephrine, Involved in regulation of certain hormone levels, Necessary for the production of adrenal hormones, Aids absorption of Iron, Aids in tyrosine utilization for melanin production (for skin & hair pigment), Regulates cholesterol, Essential for red cell formation, Essential for production of collagen; therefore responsible for health of bones, cartilage and skin, Improves immune function, Inactivates histamine.

Dietary sources of copper:

Oysters, Whelk’s, Lamb’s liver, Crab, Brewers Yeast, Brazil Nuts, Cashew Nuts, Olives, Hazelnuts, Almonds, Walnuts, Pecans, Shrimps, Cod, Peanuts, Tuna,

Copper deficiency symptoms include:

Anaemia, Oedema, Brittle bones, Irritability, Poor skin & lack of pigmentation, Haemorrhage, High blood cholesterol levels, poor immune function

RDA for Copper

US RDA: 1.5-3mg

EU RDA: 1.2mg

Warning!
Excessive Copper levels have been linked to a range of disorders from schizophrenia and learning difficulties to premenstrual syndrome and anxiety. Fortunately, many of the potential problems inherent in copper can be offset by an adequate intake of zinc, since zinc & copper compete for absorption sites in the gut. Excess zinc decreases copper absorption and vice versa.
