Can You Take Iron and Rosmarinic Acid Together?

May affect absorption

The short answer

Rosmarinic Acid is a caffeic acid ester with multiple catechol groups that strongly chelate iron, significantly reducing non-heme iron absorption.

How to arrange timing

Separate Rosmarinic Acid 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.
