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.
