Copper

A trace mineral needed for red blood cells, iron use, collagen, and nerve health. It works in balance with zinc, so taking one affects the other.

Supplements can interact with medications and aren't right for everyone, especially during pregnancy or breastfeeding, or with a chronic condition. Ask your provider before you start.

Studied for

  • Balancing long-term zinc use
  • Copper deficiency on lab testing
  • After bariatric surgery (as directed)
  • Anemia linked to low copper

Found naturally in

  • Oysters and shellfish
  • Liver
  • Cashews and sesame seeds
  • Dark chocolate
  • Lentils
What variations of copper exist?Our top pick, what to skip, and how to read the label

Label red flags

  • Long-term zinc without any copper
  • A standalone copper product on top of a multi that already has copper, without lab work

Check with a provider

  • Wilson's disease or other copper-storage problems
  • Liver disease
  • Zinc-copper balance. High zinc over time lowers copper, and copper without enough zinc can tip the balance the other way. Testing helps.
  • Signs of too much: nausea, vomiting, stomach pain, or a metallic taste
