Both have anti-oxidants in them but Green tea surpasses Black tea. It also has other health benefits. Too many to mention. Wolverine ///
Green tea is also easier on your teeth, as black tea can stain those pearly whites... if you care about that stuff...
As a matter of fact...After drinking it for about 2 weeks, I was able to sleep soundly even after drinking it at night. It has much less caffine. Green tea rocks. Its just a shame that American green tea is so different than Japanese green tea. My girlfriend in Japan is getting tired of mailing me Japanese green tea all the time!
