After one week of SFOH intake, a highly significant increase in Fe(2+) and Fe(3+) was observed in the patients' stool supernatant (p = 0.0003 and p = 0.0085, respectively), which then decreased by week 4 (t2, V2, endpoint of the study), but was still significantly higher (p = 0.0028 and p = 0.0424) than at baseline t0 (Fig. 6 ).
