What is EGCG in Matcha?
EGCG (Epigallocatechin-3-gallate) is the most abundant and powerful catechin found in matcha green tea. It accounts for approximately 50-80% of total catechin content and is responsible for many of matcha's health benefits. Studies show matcha contains up to 137 times more EGCG than regular brewed green tea because you consume the entire tea leaf.

EFSA Safety Guidelines
The European Food Safety Authority (EFSA) recommends a maximum of 338mg of EGCG per day from food sources and beverages. This equals approximately 4-5 grams of ceremonial grade matcha. Higher doses from concentrated supplements (800mg+) have been associated with liver concerns in some studies.
