WHAT YOU NEED TO KNOW

Patients taking high-dose iron supplementation long-term should have copper status monitored. Do not self-supplement with copper without medical guidance. Take iron and copper at separate times if both are prescribed.

Why this interaction occurs

Chronic high-dose iron supplementation can reduce copper absorption and induce copper deficiency over time. Iron and copper share transport mechanisms, and excess iron can displace copper at intestinal transport sites. Copper deficiency can paradoxically worsen anemia.

Evidence

Evidence level: moderate.
