Green Tea Caffeine

Green tea caffeine is a natural stimulant extracted from the leaves of the Camellia sinensis plant, the same plant used to make green, black, and oolong teas. The extraction process typically involves using water or solvents to isolate the caffeine from the tea leaves, followed by purification.

Manufacturers add green tea caffeine to beverages like sports drinks, iced teas, and sodas to provide a stimulating effect. It is used as a functional ingredient to boost energy and alertness without significantly altering the flavor profile of the product.

Green tea caffeine is generally recognized as safe (GRAS) by the FDA for use in food. The FDA has not set a specific upper limit for caffeine intake from all sources, but advises that up to 400 milligrams per day is generally safe for most adults. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated caffeine and established an acceptable daily intake. While moderate caffeine intake is generally considered safe, some individuals may experience side effects like jitters or sleep disturbances.
