Safety

Who should avoid copper bisglycinate?

The short answer

People with Wilson's disease or other copper-storage disorders should avoid copper supplementation entirely, since their bodies can't properly excrete excess copper. People with hemochromatosis or other iron-overload conditions should also check with a doctor first, since copper affects iron metabolism. As with any supplement, pregnant or breastfeeding individuals and anyone on long-term medication should consult a healthcare provider before starting.

Absolute contraindications

  • Wilson's disease. An inherited disorder (ATP7B mutations) in which copper accumulates in the liver and brain because the body cannot excrete it. Copper supplementation is contraindicated.
  • Menkes disease. A separate inherited disorder of copper transport, typically diagnosed in infancy.
  • People on copper-chelating drugs (e.g., penicillamine, trientine) used to treat copper overload.

Check with a doctor first

  • Hemochromatosis or iron overload. Because copper and iron metabolism are linked, supplement only with medical guidance.
  • Pregnancy and breastfeeding. Copper needs rise, but they are usually met by a prenatal; adding a separate supplement should be discussed with your provider.
  • Long-term medication use. Some drugs interact with copper absorption or binding — see what not to take with copper bisglycinate.
