Can You Take Copper and Iron Together?
Copper's own NIH fact sheet states it is not known to interact with any medications, and no interaction with iron is documented.
What the interaction means
The NIH Office of Dietary Supplements' copper fact sheet states plainly: "Copper is not known to interact with any medications." Iron's own NIH fact sheet does not mention copper, including in its "Can iron be harmful?" and interactions sections.
No documented interaction 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
Mineral-absorption competition (the same category as the catalog's documented Iron+Zinc and Copper+Zinc pairs) is a real, physiologically-plausible mechanism that was checked carefully here rather than assumed either way -- neither source documents it for this specific pair. Copper's own source gives an explicit negative statement, which is why this is rated higher evidence quality.
