Green Tea Extract
Concentrated catechins; linked to rare but serious acute liver injury.
What it is
Green tea extract has been associated with clinically apparent acute liver injury, including rare liver failure; catechin content varies widely.
How it works
High-dose catechin (EGCG) exposure may trigger hepatotoxicity in susceptible individuals.
What the evidence says
Safety risk (hepatotoxicity) is a core constraint; efficacy evidence varies and does not justify high-risk dosing for many users.
Safety Notes
- Hepatotoxicity is the dominating safety concern for concentrated extracts.
- Not recommended during pregnancy or while breastfeeding.
- Use caution with: history of liver injury, active liver disease.
