Is Copper Safe with Semaglutide, Liraglutide (Ozempic, Wegovy)?

If supplementing zinc for GLP-1-associated deficiency, maintain a copper-to-zinc ratio by co-supplementing with 1–2 mg of copper for every 8–15 mg of zinc supplemented. Monitor for signs of copper deficiency including anemia unresponsive to iron, neutropenia, or neurological symptoms. Avoid high-dose zinc supplementation (>40 mg/day) without copper co-administration.
Why this interaction occurs
Zinc and copper share intestinal absorption transporters (metallothionein-mediated). High-dose zinc supplementation, commonly recommended to address GLP-1-associated zinc depletion, competitively inhibits copper absorption and can precipitate iatrogenic copper deficiency. Copper deficiency manifests as anemia, immune dysfunction, and neurological deficits that may be misattributed to other causes. Maintaining the copper-zinc balance is essential when correcting zinc deficiency in GLP-1 patients.
