All about theine: impacts and misconceptions

Theine refers to the caffeine in tea, but it's the same molecule. The differences come from the context, notably tea's polyphenols. The effects of tea are not limited to caffeine: the lesser-known L-theanine has soothing properties that reduce the excitement of caffeine. The amount of caffeine and L-theanine varies according to tea type and preparation. Green and black teas have distinct caffeine levels, influenced by infusion time and temperature. This topic deserves further research to better understand the interaction between caffeine, L-theanine and polyphenols, offering a unique tasting experience.
