From Green Tea

Green tea extract is a concentrated form of compounds found in green tea leaves. It is made by processing dried green tea leaves with water or alcohol to pull out specific beneficial compounds, primarily polyphenols like catechins.

Manufacturers use green tea extract for its antioxidant properties and sometimes for its flavor. It is often added to beverages, including powdered drink mixes, energy drinks, and flavored waters, as well as some dietary supplements.

In the U.S., green tea extract is generally recognized as safe (GRAS) when used as intended. It is a source of antioxidants, which are compounds that may help protect cells from damage. Regulatory bodies like EFSA have evaluated green tea extracts, noting their antioxidant effects. Some studies suggest potential benefits for heart health and metabolism, but more research is needed to confirm these effects at typical dietary intake levels.
