I think i'm overdosing on iron from eating to much of iron-rich food? is that possible?

Only if you have..: It is virtually impossible to od on iron from just consuming iron-rich foods if you don't have some genetic abnormality such as hemochromatosis. Normally, your body will aborb enough iron and the rest will go out the other end. Hemochromatosis: your body will keep hogging the iron and will cause problem if not intervened. If u r curious/concerned, see your doc for a simple blood test. Good luck.
