Restless feeling and not able to sleep

It is possible for a person to become copper-toxic, copper-deficient or to have a condition called biounavailable copper. In the latter, copper is present, but cannot be utilized. When copper is biounavailable, one may have symptoms of both copper toxicity and copper excess. This occurs because copper is present in excess in certain organs and tissues of the body, but is not usable in other key areas. Biounavailability often occurs due to a deficiency of the copper-binding proteins, ceruloplasmin or metallothionein. Without sufficient binding proteins, unbound copper may circulate freely in the body, where it may accumulate primarily in the liver, brain and female organs.
Copper toxicity and biounavailability are seen most often. These occur almost always in people who are in a state called slow oxidation. Copper deficiency occurs most often in people who are in the state called fast oxidation. This article uses the words copper imbalance when more than one of the three types of copper problems are possible.

toxicity is usually due to:

excessive supplementation
the increasingly common problem of low levels of zinc in the diet
contaminated food and drinking water due to contact with metallic copper
external exposures such as a copper IUD or accidental agricultural overspray
elevated levels of estrogens.

Please note that it is extremely important to obtain an accurate diagnosis before trying to find a cure. Many diseases and conditions share common symptoms: if you treat yourself for the wrong illness or a specific symptom of a complex disease, you may delay legitimate treatment of a serious underlying problem. In other words, the greatest danger in self-treatment may be self-diagnosis. If you do not know what you really have, you can not treat it!
