On my squad, my top kids have their ferritin levels checked twice a year. If the kids are low (below 40), they generally take a small iron supplement and it improves.
Recently, something odd has happened and I would like some input please - My top 2 girls have been taking iron for over a year. When tested, their levels were 13.3 and 6.5, significantly below 40 and lower than their last test.
One athlete takes ProFerrin brand 10.5mg and the other
VitronC Elemental Iron (as ferronyl iron) 65 mg
Obviously something is off. Thoughts?
