Gastro-resistance and intestinal absorption of Sucrosomial® iron. (A) Gastro-resistant properties of Sucrosomial® iron compared to a sucrester-free iron preparation in an in-vitro simulated gastric fluid digestion at pH 1.2. (B) The involvement of M cells in Sucrosomial® iron uptake was evaluated using an in vitro CACO2/RajiB co-culture. The iron to protein ratio was significantly increased in co-culture cells treated with Sucrosomial® iron (SI), compared to other oral iron formulations: ferrous sulfate (FS), ferrous ascorbate (FeASC), ferrous ethylene-diamine-tetra-acetate (FeEDTA), ferrous bisglycinate (FeBIS), and control (no iron) (data are mean ± SEM, * p < 0.05) (Adapted from references [41,42]).
