Can You Take Green Tea Extract (EGCG) and Iron Together?

Dose or timing may matter

The short answer

Green tea catechins strongly inhibit non-heme iron absorption by chelating iron in the gut.

How to arrange timing

Space at least 2 hours apart. Never take iron supplements with green tea extract.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
