What is theanine?

Theanine is a naturally occurring amino acid primarily found in tea (especially green tea), responsible for giving tea its unique umami flavor and relaxing effect. Since its discovery in 1949, it has become one of the most widely studied dietary components globally.

Scientific research shows that theanine can cross the blood-brain barrier and directly affect brain function. It promotes the generation of alpha brain waves, a brainwave state associated with relaxed alertness—similar to a meditative state, both calm and focused.

Function of L-Theanine drink.

‌L-Theanine drink’s main function is to help reduce stress, relax the body and mind, and may help improve sleep quality‌.

L-Theanine (theanine) is a non-protein amino acid naturally found in tea leaves. It can help people relieve stress and anxiety by regulating neurotransmitters in the brain, such as GABA (gamma-aminobutyric acid), producing a sense of tranquility yet wakefulness. The use of this amino acid in food and beverages, especially in Japan, has been widely recognized to improve consumers’ mental state and help relax the body and mind.

In addition, although scientific research results on L-Theanine’s direct improvement of sleep quality are inconsistent, and there is currently no conclusive evidence that drinks containing L-Theanine can significantly improve sleep, some user feedback and research have shown that consuming a moderate amount of L-Theanine may help people enter the deep sleep stage faster and maintain better sleep quality. This may be because L-Theanine can regulate neurotransmitters in the human body and relieve anxiety, thereby helping to relax the body and mind and create conditions for a good sleep.

L-theanine also helps increase levels of gamma-aminobutyric acid, an inhibitory neurotransmitter with a calming effect, further enhancing its calming effects
