iron pills
I was only told to take a multi-vitamin with at least 18 mg of iron; type was never specified. Now I am on 3 times that because my 3 month followup showed my iron at the minimal acceptable level.
I do feel better at the higher dosage. I know the Ferreous Sulfate (Iron) alone is good but makes people nauseous as I have tried it before surgery and my wife uses it for restless legs syndrome.
