We could with careful control of dairy consumption (he would live on milk if allowed) and supplements get his iron in the normal range but as soon as I stopped obsessing about it, it would drop back down again. He now has very high levels and says he feels different. We saw a pedeatric hematologist at our local Children's hospital who recommended this course of action. He missed a day of school after the first treatment, he was feeling very "strange"... He is even happy he did it (which says a lot, he is terrified of needles). Hope that helps. PM me if you need more info.
