My daughter has extremely low iron and the Dr prescribed iron pills...but we wanted her to increase her intake throughout the day. So a friend loaned us their kit. We used it to make drinking water (boil 1L water for 10 min with a couple drops of citrus, add Lucky Iron). She would fill up her water jug daily. Iron pills can take 3-6 months to work, but she started to notice in basketball and soccer her legs are no longer shaky. Her hair is already showing improvement.
