Caffeine in Green Tea
While tea, especially green tea, contains caffeine, it contains far less caffeine than coffee or energy drinks. Green tea also naturally contains high amounts of EGCG (a powerful antioxidant found most abundantly in green tea than in any other natural source) and theanine (an amino acid with potent neuro-protective effects on the brain). EGCG and theanine can easily pass through the blood-brain barrier, and can improve brain function while also reducing the negative effects of stress and anxiety. These components balance the awakening effects of caffeine to produce a calm focus that gradually tapers off, as opposed to the common effects of caffeine alone: anxiety followed by a sudden crash. The important thing to note is that these components are naturally formed to exist together in green tea. And many studies suggest a synergistic reaction in which they enhance each other’s beneficial effects on mental—and overall—health.

The Bottom Line
By now it is well-known that green tea is good for you. But, not all green teas are the same. It is important to check the source and quality of the green tea you choose. Because green tea is highly absorbent of its surrounding elements, purity and a complete absence of pesticides and chemicals are critical. It is also important to consume enough green tea on a daily basis in order to properly reap its benefits. Various studies have shown that somewhere between three and ten cups of green tea should be consumed per day in order to experience its effects.
