It is a cofactor in many enzymes, including ceruloplasmin (iron transport), superoxide dismutase (antioxidant), and cytochrome c oxidase (mitochondrial energy production). An adult body contains approximately 100-150 mg of copper.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCopper is one of those minerals where the balance ratio is more important than the absolute amount. The body strictly regulates copper levels through absorption and excretion — an average diet provides enough to meet the RI of 1 mg\/day. For most people, targeted copper supplementation is therefore not necessary.\u003c\/p\u003e\n\u003cp\u003eHowever, there are specific situations where copper supplementation becomes logical. The most important is long-term high zinc use. Zinc and copper compete for absorption in the intestine — high zinc intake gradually blocks copper absorption. With chronic zinc use above 15 mg\/day (longer than 8 weeks), a functional copper deficiency can develop, with paradoxical symptoms: anemia that does not respond to iron supplementation (because ceruloplasmin — copper-dependent — transports insufficient iron), fatigue, poor wound healing.\u003c\/p\u003e\n\u003cp\u003ePremium zinc supplements therefore often add 1-2 mg of copper in the correct ratio (zinc:copper 8:1 to 15:1). For those who buy zinc and copper separately: a separate copper supplement of 1-2 mg per day is sufficient for standard zinc supplementation.
