Copper is an essential mineral for humans. It mostly appears as a co-factor in its action and thus has enormous tasks. It supports the energy balance, the blood structure, it keeps the connective tissue elastic (collagen), helps in the utilisation of iron, is needed in growth and for the reshaping of blood vessels and much more. Its role as an antioxidant can also be emphasised.
Serious copper deficiencies are rare, but many people are affected by a very low copper level in the blood. This can lead to very diverse diseases after some time; the best known is vitiligo (white spot disease), which can be improved relatively quickly with high doses of copper tablets (& co-factors). But also, in the case of unclear cardiac arrhythmias, arthrosis, rheumatism or osteoporosis, the copper level should be checked.
