Struggling with Iron Absorption Due to Ileostomy

I have difficulty absorbing enough iron. I get an infusion every four or so months. Does anyone have a tried and true method for taking in iron? I have an ileostomy. (I lost my entire colon and then 12 more feet of small intestine to cancer.)

As crazy as this sounds, whenever I am/was iron deficient, I would eat Shreddies cereal for breakfast, lunch, or as a snack. It was an easy (and delicious) way for me to increase my iron levels.

I take an iron supplement but also take vitamin C to help absorb the iron. Also, I take Ferrous Gluconate (the iron supplement) instead of Ferrous Sulfate because my gastroenterologist told me that I would not be able to absorb the Ferrous Sulfate as easily having an ileostomy. Hope this info helps.
