Green Tea Extract And Caffeine From Tea

Green tea extract is a concentrated form of compounds found in green tea leaves. It is typically made by steeping green tea leaves in hot water or other solvents to extract beneficial compounds like antioxidants. The liquid is then dried to create a powder or concentrated liquid.

Manufacturers add green tea extract for its antioxidant properties and as a natural source of caffeine. It is often found in energy bars, snack bars, and beverages where a boost of energy or a health-promoting ingredient is desired.

Green tea extract is generally recognized as safe (GRAS) by the FDA when used as intended. It is a source of caffeine, which can increase alertness and energy levels. High doses of green tea extract have been linked to liver issues in some rare cases, though this is not typically seen with amounts found in food products. The European Food Safety Authority (EFSA) has evaluated green tea extracts, noting that while they contain beneficial compounds, high doses can pose risks.
