What effect does the Green Tea have in Xtra?
Xtra contains 220 mg of green tea extract per serving, which contains a maximum of 7% caffeine. So at the maximum, one ounce of concentrate or a 3.3 oz mini will provide only 15 mg of caffeine. That’s the equivalent of a sip of coffee (regular brew coffee contains 100 mg caffeine per 6 oz cup). In addition, because green tea also contains theanine, caffeine effects are counteracted and little, if any, stimulation actually occurs. Theanine contributes a relaxing property unique to green tea. The caffeine-counteraction effect of theanine is the subject of currect chemical study.
