sucrosomial iron sucrosomial iron sucrosomial iron is a new oral iron preparation containing ferric pyrophosphate covered by phospholipids plus sucrose ester of fatty acid matrix. this allows the molecule to be absorbed in the gastrointestinal tract by trans-cellular, para-cellular and m-cells independently of hepcidin and due to gastro-resistant properties, it does not cause the side effects such as gastric irritation which is commonly associated to oral iron.
