Dose response of NA on reduction in Fe-FZ complex formation is shown. Absorbance of Fe-FZ decreased with addition of increased dose of NA (A). FZ selectively binds to Fe²⁺ and not to Fe³⁺ as shown by increased absorbance in presence of FeSO₄ and not in the presence of FeCl₃ (B). The results suggest the Fe²⁺-chelating ability of NA. *p < 0.05, ***p < 0.001 as compared to control. Abbreviations are as in the text.
