I had to laugh when I read this thread title, because I know exactly how you feel. When I found out that I had low iron two years ago (my serum ferritin was at 12, which is the lowest measurable) I was so excited. Finally something tangible to fix!

I've had really good results with the carbonyl iron supplements (brand name Feosol, you can find it at average pharmacies like Walgreens, etc). Iron salts (ferrous sulfate, ferrous fumarate, etc) all upset my stomach and GI tract.

Also, remember to take B12, folic acid, and vitamin C together with iron. These are all important cofactors for absorbing iron and building new blood cells.

Good luck!
