Copper in health copper deficiencies. Fortunately, diagnosis of copper deficiency in children is clear and reliable once the condition is suspected. Supplements under a physician's supervision usually facilitate a full recovery.

If an insufficient amount of copper is ingested for a short period of time, copper stores in the liver will be depleted. Should this depletion continue, a copper health deficiency condition may develop. If too much copper is ingested, an excess
