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.
