Can You Take Cacao Extract and Iron Together?

Dose or timing may matter

The short answer

Cacao contains polyphenols and oxalates that bind to iron, significantly reducing its absorption. This is a well-documented interaction.

How to arrange timing

Separate cacao extract 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.
