Teddy, iron and zinc supplements will not clean you out. The only treatment for lead poisoning is intravenous chelating agents that bind the heavy metal. The treatment also binds iron, zinc and copper which then have to be supplemented-maybe that's where you heard about that connection-?
Men don't need iron. Too much iron in men is toxic. In fact, the only people who need iron are those who are bleeding. It makes more sense to find the reason for the bleed than to simply replace the iron and let yourself keep bleeding.
