KW123--A value of 10 means that you have no iron left in your stores, so it would be very important to build them to a healthy level. I would think that you would want to try to get this number between 50-70.
I am not anemic along with many others here that DO treat a low ferritin through iron supplementation. You just have to watch your ferritin levels so that you don't get iron overload. This is a very hard thing to happen to people that are already having a problem with low ferritin and/or anemia and it rarely happens I am told. This is more of a case of HH that is a hereditary disease or someone that receives large amounts of iron through IV. and even they do not seem to hold on to iron from what I have read here.
