Copper and Your Health

You may think of copper as something to do with wiring and electronics, but it's also an important mineral that you take into your body when you eat some types of seafood, nuts, veggies, fruit, and other foods. You need it for growth and your overall health.

Copper plays a part in many of your body's organs and systems. It helps you:

Because copper has a role in these important tasks, it can help keep certain conditions at bay, such as:

  • Anemia (low red blood cell count)
  • Osteoporosis (bone loss, most often found in women)

When You Don't Get Enough

Your body doesn't need much copper, but when you're low, your health may take a hit. You need larger amounts as you age. The Recommended Dietary Allowances (RDA) for copper are:

  • Birth to age 3: 200 micrograms (mcg) -- 340 mcg
  • Ages 4-8: 440 mcg
  • Ages 9-13: 700 mcg
  • Ages 14-18: 890 mcg
  • Ages 19 and older: 900 mcg

It's rare to have a serious lack of copper in your body, but some signs that you may need more of it are:

Sources of Copper

Many foods have copper in them. Eating more of them will help you meet your daily needs. For a copper boost, fill up on:

  • Nuts (cashews, filberts, almonds, pistachios, pecans, macadamia nuts, peanuts)
  • Beans (lentils, soybeans, navy beans)

To get more copper in you, your doctor may suggest you take copper tablets or a multivitamin that has copper in it. The dose and how often you take them depends on your condition. For people with Menkes disease, doctors might prescribe copper injections.

It's important to strike a balance between the amount of copper and zinc in your body. If you take a copper supplement, you should take a zinc supplement, too. Don't take them at the same time. Wait at least 2 hours after taking zinc to take your copper dose.

Always talk to your doctor before starting copper supplements.

When You Get Too Much

Having too much copper in your system is rare, but it's possible. Some people take supplements even though they have enough copper already.

Some people get a little extra copper without knowing. It can seep into food from certain types of cookware. If you drink well water or water that goes through copper pipes, you might get more copper than most people.

Wilson's disease is a condition that causes a copper buildup in your brain, eyes, liver, and kidney. If you have this disease or genetic conditions like idiopathic copper toxicosis or childhood cirrhosis, you shouldn't take copper supplements.
