Jumping on the bandwagon of healthy drinks, EQ8 certainly has the credentials for being healthy. It contains no sugar other than that found in the medley of fruit juices it is concocted from, and the caffeine sources are guarana and green tea based too. Sadly the can gives no clue as to the actual caffeine content so I have to assume it is low. But, as energy drinks go, it does pick you up if not as forcefully as the synthetic varieties. Taste-wise, sadly it disappoints. This flavour is quite sour and could have done with added sugar to be honest!
