While traditional green tea infusions are considered safe, rare cases of liver injury have been reported in individuals taking high-dose supplements containing green tea catechins, including EGCG. The potential for EGCG to be bad for your liver largely depends on the form and concentrated dosage consumed.

While a typical cup of green tea provides 90–300 mg of EGCG, supplements can contain much higher, concentrated doses, with research from EFSA suggesting intakes at or above 800 mg/day can pose a risk of liver injury. Understanding this difference is crucial for anyone wondering what happens if I take too much EGCG.
