What the interaction means

Omega-3's dedicated Interactions with Medications section names only warfarin and similar anticoagulants; copper does not appear anywhere in either omega-3 fact sheet (copper is mentioned only once in the Health Professional fact sheet, as a component of the unrelated AREDS eye-health supplement formulation, not as an omega-3 interaction). This repository's existing copper content contains no mention of omega-3 or fish oil.

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

Omega-3's side was checked directly this pass (both fact sheets, full text). Copper's own source was not independently re-fetched this pass; this relies on a repository grep of previously-verified copper content, which found no mention of omega-3/fish oil.
