In general, "junk food" is high in iron. And many peoples' diets these days are not much better than "junk food" anyway. Personally, I would avoid this "Floridated Iron and Herbs" supplement, unless you know for sure that it is exactly what you need. I am concerned that many "alternative health experts" give people things that they don't need so that the patient thinks that he/she is truly and expert and keeps coming back.
Knowing what I know now, I would try to get healthy by avoiding stressors, and an iron supplement can indeed be a stressor. They told me I was low in B12, and I would guess that you are more likely low in one or more B vitamins that in iron. If you want iron, eat a dozen raisins with each meal, which is safer than meat or supplements.
Above all, do not take a little advice from one person and a little from another and mix them together, then blame them both when it fails. Be consistent with one line of advice and see what happens. Give it at least several weeks. About 2-3 months seems best.
