Can I Take These?

Can You Take Calcium and Copper Together?

No documented interaction identifiedEvidence: High

See the full Calcium page and Copper page for other reviewed interactions and reference information.

What the interaction means

The NIH Office of Dietary Supplements' copper fact sheet states plainly, in answer to "Does copper interact with medications or other dietary supplements?": "Copper is not known to interact with any medications." The calcium fact sheet's interactions section does not mention copper.

No documented interaction between Calcium and Copper was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

Copper's own source gives an explicit negative statement (not just silence), which is why this is rated higher evidence quality than the other 'no documented interaction identified' pairs in this batch.
