A number of us are taking iron therapy, involving either oral supplements or IV iron infusions (like me). You probably know that there is some danger of iron overload with iron therapy. You can minimize that danger by keeping your TSAT (transferrin saturation) level below 45%. You'll need to calculate that: TSAT is serum iron divided by total iron-binding capacity (TIBC), which corresponds to circulating iron. (Both of those numbers should appear in your blood test results. If not, ask for them.)

The IRLSSG paper on clinical guidelines for iron therapy, written by many of the RLS experts and cited often here, states that iron therapy should not be considered unless TSAT is below 45%, to minimize the possibility of iron overload. So keep an eye on both your TSAT and ferritin.
