L-theanine is an amino acid that is said to have a variety of positive effects, for example on the heart, circulation and nervous system, as well as against high blood pressure.
Theanine reaches the central nervous system via the bloodstream, where it is also said to stimulate the production of dopamine. Dopamine provides the body with a zest for action and a good mood.
Theanine is mainly found in teas from the early 1st plucking, over the course of the year the content slowly decreases. The theanine content is noticeable through a sweet, soft aroma with less bitterness, which is best dissolved at low infusion temperature.
