Does Tea Affect Manganese?

May affect absorption or how you feel

The short answer

Tea contains high levels of manganese itself, and tannins can interfere with manganese supplement absorption, risking both under- and over-intake.

How to arrange timing

Account for tea's manganese content and separate supplements by 2 hours.

Important context

The effect can also change with food amount, supplement 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.
