Green tea extract

Green tea extract is a concentrated form of the beneficial compounds found in green tea leaves (Camellia sinensis). It is produced by drying and grinding tea leaves, then extracting the active compounds using water or organic solvents. The resulting liquid is then concentrated and dried to form a powder.

Green tea extract is primarily added for its flavour and perceived health benefits, often marketed as an antioxidant. It is commonly found in beverages, particularly green teas and protein powders, where it contributes a characteristic taste and colour.

Green tea extract is not listed as a food additive on the Register of Food Additive Authorisations and is therefore not regulated as such in Great Britain. It is considered a food ingredient. EFSA has evaluated green tea catechins in the context of health claims, but has not set a numeric acceptable daily intake (ADI) for green tea extract itself. Some studies suggest potential benefits related to antioxidant activity, but evidence for specific health outcomes at typical dietary intakes is mixed and requires further research. High doses of green tea extract supplements have been linked to liver issues in rare cases, but this is not typically a concern with consumption from food products.
