L-theanine is a substance that is sold in health food stores or herbalists, independently of the tea. It is not that it can be made in the form of an infusion, it is in the form of capsules or tablets. It has many benefits Apart from those already mentioned, it also naturally raises the hormone of happiness, without the need to introduce chemical substances into the body.

L theanine tea. What is it?

L theanine is an amino acid found almost uniquely in the tea plant, Camellia sinensis. In green tea, this compound represents 1 to 4% of its dry weight. It has been a dietary supplement for 30 years and it was in Japan where it became popular in 1994 as a way to relieve stress and encourage relaxation.

It then made its way to North America and now L-theanine tea can be found as an ingredient in food and beverages, as well as a dietary supplement. Between the benefits of this tea there is its rapid action, its effects occur within ½ hour of consuming it and last between 8 to 12 hours.

Green tea and L theanine

Any discussion that mentions green tea should include the L theanine, because during the process of photosynthesis it is the one that produces the catechins. Also, it is the one that gives the flavor and aroma that characterizes the tea.

The green tea with the highest amount of L-theanine is Matcha, because before its harvest (three weeks) its plants are placed in the shade. This causes more theanine in its leaves because the photosynthesis process is minimized, giving it the characteristic taste of matcha tea. Being in the shade, chlorophyll is concentrated in the tips of the plants and is what gives the matcha its bright green.

Due to the above, traditional green teas contain low tannins (5 mg per cup). The one that is grown in the shade (this is the case of matcha tea) contains 9 times that amount (between 25 to 30 mg per cup). Caffeine and L theanine in matcha tea have almost the same amounts.
