How Do I Choose the Best Copper Supplement?

A copper supplement is a capsule or pill that contains copper, an essential mineral found in grains, shellfish, and green leafy vegetables. The nutrient helps your body absorb iron and it also has properties that help to regulate your heart beat and blood pressure. If you are treating decreased blood copper levels, then a pure copper supplement is generally your best option. Multivitamins and other types of supplements may also contain copper.

Although you should not use copper supplements without first consulting with your doctor, you can determine which type of capsules are the most appropriate to take. As of 2011, the American Cancer Society recommends taking no more than 10 milligrams of copper each day, and the dosage limits vary in children by age. If a particular copper supplement has more than 10 milligrams per dosage, you will likely want to avoid such a brand, unless otherwise directed by a physician.

A physician will usually recommend a copper supplement if you have a deficiency of the mineral. Keep in mind that several blood tests might be needed to determine your copper levels, because liver metabolism of the mineral can sometimes cause different lab results. Regular blood tests are likely needed if you are being treated for copper deficiency to ensure that you are not taking too many supplements, which can result in toxicity. Too much copper in the body is rare, but it is a serious complication that can cause kidney failure and liver damage.
