What would be the best iron supplement for me. I take centrum vit, hydroxyzine, hydralazine and imdur & metaprolol, extra E, C, b12 & b6 viactive for calcium. I am an active 87 year old with a urostomy for 17 years and basically a healthy person.I tried iron glycinate and feet were swollen, stomach discomfort, not loose bowels but 2 or 3 times in am. Also I take Prilosec daily & 81 mg asprin.
