Natural L-theanine Powder
What are the functions of theanine?
L-theanine is a unique amino acid found in green tea and an abundant component in high-grade and fresh tea leaves. L-theanine can improve sleep quality, relieve stress, and enhance concentration. Since it is an ingredient in green tea, some people may think they should only drink tea. However, even if they do so, they may not achieve the desired effects. L-theanine is a highly safe substance. It does not make people feel sleepy during the day, is easy to use, and has minimal impact on the taste of products containing it.
