What is L-Theanine Powder Green Tea Extract?

TIZAN supplies natural L-Theanine powder green tea extract, and we produce it with green tea leaves.

L-Theanine, also known as L-γ-glutamyl-ethyl amide and N5-ethyl-L-glutamine, is an amino acid analog of the proteinogenic amino acids L-glutamate and L-glutamine and is found primarily in particular plant and fungal species. Scientists discovered it in 1949, then isolated it from green tea, which have high theanine content.

As an analog of glutamate and glutamine, the small intestine absorbe the theanine in common preparations after oral ingestion; its hydrolysis is L-glutamate and ethylamine and occurs both in the intestine and liver. It can also cross the blood–brain barrier intact and register pharmacological effects directly.

It may help the body’s immune response to infection by boosting gamma delta T cells’ disease-fighting capacity. The report pointed out that it raises brain serotonin, dopamine, and GABA, with possible improvement in specific memory and learning tasks.

L-Theanine and caffeine’s combination promotes faster simple reaction time, faster numeric working memory reaction time, and improved sentence verification accuracy. Due to this, the combination has become popular over recent years as a nootropic supplement typically found in the form of a pill, drink, or gum.

Japan approved it for use in all foods, including herb teas, soft drinks, desserts, Etc., with some infant food restrictions. It provides a unique brothy or savory flavor to green tea infusions. FDA generally recognizes it as safe (GRAS) as an ingredient and sold it as a dietary supplement in the US.

What is natural L-Theanine Powder used for?

Traditional/Ethnobotanical uses

Second only to water, tea is the most widely consumed beverage in the world. It was discovered as a constituent of green tea in 1949 and was approved in Japan in 1964 for unlimited use in all foods, including chocolates, soft drinks, and herb teas, except infant foods. It also provides a unique umami (brothy or savory) taste and flavor to green tea infusion.

General uses

It may help relieve stress by inducing a relaxing effect without drowsiness and may also possess immunologic attributes. It may also have effects on the cardiovascular system and play a preventative role in cancer; however, limited clinical information is available to support these claims.

Side Effects

Most research on the basic actions of L-theanine has been done in animals. Some preliminary human studies, typically using doses of L-theanine about 10 to 20 times higher than that in a cup of tea, have suggested possible benefits, such as the following:

In a Japanese study in the Journal of Physiological Anthropology, college students who took it experienced less anxiety and had smaller increases in blood pressure when under psychological or physical stress than when they took a placebo.

Similarly, another Japanese study in Pharmacology, Biochemistry, and Behavior found that graduate students who took it experienced less anxiety (as measured by a questionnaire and by a salivary marker for stress) when they were assigned stressful work in a pharmacy, compared to a placebo.

In a Canadian study in Alternative Medicine Review, it improved some aspects of sleep quality in boys with attention-deficit hyperactivity disorder (ADHD).

In a preliminary Israeli study in the Journal of Clinical Psychiatry, it helped relieve anxiety symptoms and augment antipsychotic treatment in patients (ages 19 to 55) with schizophrenia.
