Women have a higher demand for iron then men due to monthly menstrual flow. You do not want your daughter to become toxic with Iron supplementation which is worse. Replenish Iron through food sources. There are 2 types of iron in our food sources, Heme iron and Non-Heme iron. Heme iron is from animal sources (meat, dairy) and Non-Heme is plant sources (beans, nuts, potatoes). Non-Heme iron has more iron then Heme iron , however, it does not absorbed well into our bodies so it is important to eat foods with Vitamin C and Heme iron foods to enhance absorption. For example, chicken with beans and a fresh orange; drink orange juice with the iron supplement; or have mashed potatoes with meat at a meal. High Iron food sources are all meats, fish, dark green vegetables, beans, enriched rice (cooked), enriched pastas (cooked), and whole wheat breads. Did the Doctor look at folate or Vitamin B12 levels for possible other types of anemia? Hoped this helped you.
Thank you for the suggestion. I'm not sure iron replenishment thru food will be enough but we are working on it. Actually, she just had labs drawn this week so we'll see if there's been any progress.
