Green tea, as well as oolong, white tea, & black tea, are the leaves of the plant Camellia sinensis. Caffeine is naturally occuring in the Camellia sinensis, however the caffeine (or theine in tea) is a third to a half the amount found in a standard coffee. Black tea has more caffeine than green tea, and green tea has more than white tea varieties. White tea has minimal caffeine. Oolong has between green and black teas in caffeine content.
Modern barista made coffee, especially in large keep cup may even contain 3 or even 4 times the caffeine in black tea!
Unlike the rush and crash from the caffeine in coffee, it is claimed that 80% of the caffeine in tea remains unabsorbed by the human body, yet it can have a number of benefits such as stimulating the nervous system & improving circulation.
It is recommended that people avoid consuming drinks containing caffeine after 3pm as the caffeine can prevent people falling asleep and having a restful night.
Whilst people may believe that tea containing caffeine is a diuretic, some evidence shows that the net effect of drinking tea is beneficial, with positive hydration. However, choosing a lower caffeine option such as green tea or white tea would be more hydrating. We believe that swapping any tea over a strong coffee, or soft drinks laden with sugar, is the way to go!
Another benefit of green tea is high quality leaves contain Theanine. The theanine in green tea may improve mental cognition, lift a person’s mood, and increase brain serotonin and dopamine levels.
