Precautions

Concentrated extracts are not the same as drinking tea. High dose supplements have been linked to liver injury in rare cases, so stop and see a doctor if you notice yellowing of the eyes, dark urine or persistent nausea. Green tea reduces iron absorption, so keep it apart from iron tablets, and it can interact with blood thinners. Take it with food rather than fasting.
