Can you take Curcumin and Iron together?

NoteAnimal / lab only

Probably fine for most people, but separate them if you are treating low iron.

What to do: If you are iron-deficient, keep curcumin at least 2 hours away from iron.

Curcumin binds iron

Curcumin is an iron chelator. In mice, curcumin lowered iron stores and caused mild anemia; human data are lacking.

Evidence level: Animal / lab only — Evidence limited to animal or cell studies.
