I have had diabetes type 1 for 41 years. anemia for 4 to 5 years.caused by lower functioning kidney which was caused by the diabetes. on procrit injections once per month. I have lots of side effects from the procrit. I heard about intrinsic factor supplements. I have also heard about IGF supplements. Would either of these increase my absorption capabilities or reverse my current anemia issue. I have been on iron supplements twice a day without much change for several years. according to what i have seen so far, absorption of iron and b vitamins are inhibited by this condition.
