Interactions
enhances. Vitamin C reduces Fe3+ to Fe2+ and chelates iron, increasing non-heme absorption 2-6 fold
inhibits. Calcium inhibits both heme and non-heme iron absorption by 50-60% when taken together
competes. Compete for DMT1 transporter; simultaneous intake reduces both mineral absorption
inhibits. Polyphenols in coffee/tea chelate non-heme iron, reducing absorption by 40-90%
competes. Divalent cation competition at DMT1 transporter
inhibits. Curcumin chelates iron; beneficial in iron overload but problematic in iron deficiency
