Copper glicinate is the important drug than other therapies and the other therapies was not succesfull. In paraclinical examinations copper deficiency separate by equivalence plasma serum.Conclusion: The copper deficiency was occur in stress situation.In initial clinical sign was not controlled by therapies and should be advised copper glicinate.Normal cupper glicinate dose lead to high equivalence of plasma copper and regulate level equivalence of copper and minerals.
