Source ? As copper is not synthesised by the body, our diet must contain a sufficient quantity of copper. Copper is found in most types of food: starches, leguminous vegetables, whole cereals, offal, crustaceans, fruit and vegetables. Copper deficiency is therefore rare. Mineral water can also provide a good source of copper.
What does it do ? Copper contributes to good nervous system and immune system function, and also helps protect cells against cellular ageing thanks to its antioxidant properties. It acts on our skin and is involved in hair pigmentation. Finally, copper plays a part in the transportation of iron round the body, essential for ensuring transportation of oxygen from the lungs to the cells.
For whom ? Elderly people and those with anaemia; everyone as winter comes, and those with significant oxygen stress (smokers, sporting people, those in polluted environments).
The recommended intake is 1 mg daily for an adult, and 2 mg daily for pregnant and nursing women.
