... Iron can go either way with copper load, depending on
calcium and zinc status. Copper is synergistic with calcium,
but opposes zinc during uptake (but not storage). So in a
clinical sense, iron is not affected by copper unless there
are significant abnormalities with calcium or zinc status as
a result of both - calcium and zinc - being iron
antagonists.
