Summary
Tea polyphenols such as tannins and catechins bind iron in the gut and can reduce absorption of oral iron. This may lessen the benefit of ferric maltol in iron deficiency.
What this interaction means in plain words
Ferric maltol and Green tea can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Ferric maltol belongs to Miscellaneous; Green tea belongs to Gastrointestinal Tract.
Why it happens
Polyphenols chelate non-heme iron in the gastrointestinal tract, reducing its absorption.
