Can You Take Iron and Chinese Gall Together?

Dose or timing may matter

The short answer

Chinese Gall (Wu Bei Zi) is one of the richest natural sources of gallotannins, which very strongly chelate iron. Iron absorption is severely reduced when taken together.

How to arrange timing

Separate Chinese Gall and iron supplements by at least 3 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.
