Hi Eric_S

I have a family member with Crohn's Disease who has anemia - but he absolutely cannot tolerate any iron supplement he has ever tried, not even in a multivitamin/mineral supp.
So he simply eats as much iron rich food as he can, and over recent years his anemia has stabilized...he still tests a little low for iron but not such that his doctor feels is any cause for concern.

You will find a list of foods that are good sources of iron in this article from Mayo Clinic
