Copper

Overview

Copper is a mineral. It is found in foods such as organ meats, seafood, nuts, seeds, wheat bran cereals, grain products, and cocoa products. The body stores copper mostly in the bones and muscles. The liver regulates the amount of copper that is in the blood. Copper is used as medicine.

Copper is most commonly used for treating copper deficiency and the anemia it may cause. Having too little copper (copper deficiency) is very rare. It sometimes occurs in people who get too much zinc from diet or supplements, have intestinal bypass surgery, or are fed by feeding tubes. Malnourished infants can also have copper deficiency.

Classification

Is a Form of:

Mineral

Primary Functions:

Copper deficiency

Also Known As:

Copper Sulfate, Cu, Cuivre, Cuivre Élémentaire

How Does It Work?

Copper is involved in many of the natural processes in the body.

Uses

  • Copper deficiency.Taking copper by mouth at recommended levels or given intravenously (by IV) by a healthcare provider is effective for treating copper deficiency and anemia caused by copper deficiency.
  • Taking copper in combination with zinc, manganese, and calcium might slow bone loss in older women.

Recommended Dosing

The following doses have been studied in scientific research:

BY MOUTH:

  • For copper deficiency: doses up to 0.1 mg/kg of copper as cupric sulfate per day.

The National Institute of Medicine has determined Adequate Intake (AI) of copper for infants: 0 to 6 months, 200 mcg (30 mcg/kg/day); 7 to 12 months, 220 mcg (24 mcg/kg/day). Infants should get all their copper from food or formula, unless a healthcare provider recommends supplements and provides follow-up care and monitoring.

For children, a Recommended Dietary Allowance (RDA) of copper has been set: 1 to 3 years, 340 mcg/day; 4 to 8 years, 440 mcg/day; 9 to 13, 700 mcg/day; 14 to 18 years, 890 mcg/day.

For men and women age 19 years and older, the RDA of copper is 900 mcg/day.

For pregnancy, the RDA is 1000 mcg/day, and breast feeding 1300 mcg/day for women of all ages.

The Tolerable Upper Intake Level (UL), the maximum amount for which no harmful effect is expected, has been established for children and adults. The ULs for copper are: children 1 to 3 years, 1 mg/day; 4 to 8 years, 3 mg/day; 9 to 13 years, 5 mg/day; 14 to 18 years (including pregnancy and lactation) 8 mg/day; adults age 19 and older (including breast feeding), 10 mg/day; pregnancy age 19 and older, 8 mg/day.

INTRAVENOUS:

  • For copper deficiency: Healthcare providers give copper intravenously (by IV).
