Does EGCG cause liver damage?
Based on safety assessment of green tea products, the European Food Safety Authority recently found that green tea supplements providing more than 800 mg of EGCG per day are linked with a greater risk of liver injury. Keep in mind that this possible risk of liver injury relates to green tea EXTRACT.
Does Lipton green tea Contain EGCG?

The most expensive was Teavana Green Tea Gyokuro at 94 cents per serving, despite its high level of EGCG (86 mg).
Does coffee contain EGCG?
Epigallocatechin gallate (EGCG) and chlorogenic acid (CGA), are the most abundant polyphenols in green tea and coffee, respectively. Studies in test tubes, animals, and humans suggest they may have potent anticancer effects ( 21 , 22 , 23 ).
How much EGCG is safe?
A safe intake level of 338 mg EGCG/day for adults was derived from toxicological and human safety data for tea preparations ingested as a solid bolus dose. An Observed Safe Level (OSL) of 704 mg EGCG/day might be considered for tea preparations in beverage form based on human AE data.
Does Lipton green tea have EGCG?

How much EGCG is toxic?
Based on allometric scaling, the doses of EGCG observed to cause toxicity in the study (500 – 1500 mg/kg) correspond to a dose in humans of 30 – 90 mg/kg assuming a daily requirement of 12 and 2000 kcal for mice and humans, respectively (Schneider et al., 2004).

What does EGCG stand for?
EGCG stands for epigallocatechin gallate. It’s a chemical substance found in green tea, and is considered to be responsible for most of the healthy benefits associated with green tea. In particular, EGCG is a polyphenol, which helps with the production of certain proteins and alkaloids.
How much EGCG daily?
Daily daily intakes equal to or above 800 mg of EGCG per day increases the blood levels of transaminases, an indicator of liver damage (17). One group of researchers suggested a safe intake level of 338 mg of EGCG per day when ingested in solid supplemental form (18).
