<unk>  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.
