Can You Take Iron and Plant Enzymes Together?

May affect absorption

The short answer

Plant enzyme blends may alter the digestive environment and affect the absorption rate of iron supplements taken simultaneously. The enzymatic activity can change gastric pH and interfere with iron dissolution.

How to arrange timing

Take iron supplements at least 1 hour apart from plant enzyme blends for optimal iron absorption.

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.
