L-Theanin Capsules – For Focus and Relaxation
L-Theanin is a natural amino acid from green tea that promotes focus and relaxation. Discover our premium L-Theanin capsules with the branded raw material NeuroTeyanin®.
Green tea has been appreciated for centuries in various cultures and has a rich tradition, particularly in East Asia. To produce the tea, like black tea and oolong tea, the leaves of the Camellia sinensis plant are used. Compared to these tea varieties, green tea is, however, processed and fermented less, which gives it its characteristic green colour.
Traditionally, green tea is attributed a variety of positive properties, which are also confirmed in modern studies. An important reason for these effects is the L-Theanin it contains. L-Theanin is an amino acid that is found primarily in green tea and can have a positive effect on our cognitive abilities. In the leaves of green tea, L-Theanin occurs in a natural concentration of approx. 2–5%.
L-Theanin Effect Explained: These Are the Advantages
In several studies, it was observed that participants showed increased alpha-wave activity in the brain after taking 50 to 200 mg of L-Theanin. Alpha waves are a specific frequency range in the brain that is associated with a state of relaxed concentration. This describes the state when your mind is calm, but you are nonetheless awake and focused. (White et al., 2016)
This mechanism works via the influence of L-Theanin on the amount of neurotransmitters such as GABA (gamma-aminobutyric acid), dopamine and serotonin. Through L-Theanin, GABA accumulates increasingly in the brain and thus provides a relaxing effect. Similarly, the levels of other neurotransmitters such as serotonin and dopamine can increase, which explains improved attention and cognitive performance.
Studies have shown that L-Theanin additionally has the following effects:
-
Participants felt less depressed
-
Sleep disorders and the use of sleeping pills decreased
-
Verbal fluency and in particular letter fluency improved (Hidese et al., 2019)
