What is the daily copper supplementation dose for deficiency?

• A. 0.5 mg/day
• B. 1 mg/day
• C. 2 mg/day
• D. 3 mg/day

Answer: (C)

Copper is an essential trace element needed to support enzymes like ceruloplasmin and cytochrome c oxidase. When someone is deficient, replacing copper helps restore those essential functions and improve symptoms over weeks to months. The typical therapeutic daily dose for adults is about 2 mg of elemental copper. This amount is enough to replenish stores and correct deficiency without venturing into higher risks of toxicity. Smaller doses, such as 0.5 or 1 mg daily, are usually not sufficient to fix the deficiency promptly. A higher amount, like 3 mg daily, offers no added benefit for routine deficiency and raises the chance of adverse effects. So, 2 mg per day is the standard supplementation level used to treat copper deficiency.
