So many multivitamins, etc, omit iron out of fear of iron poisoning, that one can easily err on an individually-deficient side.

(The optimal window also appears narrow enough -- even people with temporary anemia must limit supplements -- that I would not attempt to rely on cookware to supply my iron requirements.)

I'm definitely not suggesting that iron pans should be a dietary supplement. I'm just doubtful that they're responsible for much iron poisoning.

Yes, my parenthetical add-on was directed at the comments in general, not your comment. I did not intend to imply that you implied...
