Overview
•36 mg iron per capsule exceeds typical maintenance doses and should only be used under medical supervision with confirmed deficiency to avoid overload.
•Chelated Ferrochel form generally causes less GI upset than ferrous sulfate, but constipation, nausea, or dark stools remain possible.
•High-dose iron can interact with levothyroxine, tetracyclines, quinolones, or proton pump inhibitors by reducing absorption of each.
•Active methylfolate and methylcobalamin forms are well-tolerated but may pose issues for those with certain rare metabolic conditions.
