Can You Take Iron and Oleuropein Together?

May affect absorption

The short answer

Oleuropein is an olive leaf polyphenol with catechol groups that chelate iron. Studies show oleuropein can significantly reduce non-heme iron absorption.

How to arrange timing

Separate Oleuropein and iron supplements by at least 2 hours.

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.
