Does Tea Affect Milk Thistle?

Amount or timing may matter

The short answer

Green tea catechins may stress the liver at high intakes. Combining with milk thistle (taken for liver protection) may indicate excessive hepatic load.

How to arrange timing

If taking milk thistle for liver support, moderate tea intake and separate by 2 hours.
