Firliposomal iron has a molecular weight related to ferrous fumarate, which is available in a dosage of 210 mg. This form of iron is utilized for its bioavailability, particularly when sourced from ferrous bisglycinate chelate or sodium iron III EDTA. HealthVit offers a formulation of ferrous fumarate that is beneficial for those seeking to improve their iron intake.
