I'm 54 years old and have been taking B-12 and Niferox Forte 150mg (iron supplement) for the past 5 years. My doctor said that I'am anemic and that my body is not absorbing iron. I had a colonospy and a Egd done and they showed no bleeding. My doctor now is talking about iron infusions. Do they really help with energy? I'm also a diabetic. thanks for any help you can give me.
