Can You Take Glucomannan and Iron Together?

Dose or timing may matter

The short answer

Glucomannan is a viscous soluble fiber that can trap minerals including iron in its gel matrix, significantly reducing absorption.

How to arrange timing

Take iron supplements at least 2 hours before or after glucomannan.
