What is L-Theanine?

Theanine is an amino acid found only in tea, where it is most abundant. L-theanine is synthesized in the roots of tea plants, transferred to the leaves through the branches, and accumulated in the leaves. Under sunlight, theanine will be converted into catechuic acid. Therefore, L-theanine has a higher content in light-sheltered high-grade green tea, but a lower content in general crude tea leaves, while the content of polyphenols is increased.

Theanine is a characteristic amino acid in tea, which is synthesized by glutamic acid and ethylamine in the root of the tea plant under the action of theanine synthetase. It is an important substance to form the taste of tea, which is mainly characterized by freshness and sweetness and is the main component of tea. Twenty-six amino acids (6 non-protein amino acids) were identified in tea, which generally accounted for 1%-5% of the dry weight of tea, and theanine accounted for more than 50% of the total free amino acids in tea.

As the most abundant non-protein amino acid in tea, theanine is safe and has no side effects. It has many biological activities, such as anti-oxidation, immune regulation, anti-aging, and antagonizing cell excitotoxicity caused by glutamate excess. At the same time, l-theanine, as an alkylamine, can activate γ-T immune cells, promote cell proliferation and cytokine secretion, enhance the ability to resist tumor cells, reduce the infection of external microorganisms, and reduce the incidence of cold and influenza.


The efficacy of L-Theanine.

  1. Affect the changes in the brain nerve transmission material and enhance memory.
  2. Theanine has a sedative effect and may prevent neurological disorders, insomnia, menstrual syndrome, etc.
  3. Theanine can protect nerve cells may be used for the prevention and treatment of cerebral embolism, cerebral hemorrhage, cerebral stroke, cerebral ischemia, and senile dementia, and other diseases.
  4. Theanine has the effect of lowering blood pressure.
  5. Theanine can enhance the efficacy of anticancer drugs.
  6. Theanine has the effect of antipyretic and heat relieving.
  7. 7. Theanine can improve immunity.

What are the uses of L-Theanine?

  1. Seasoning. Mainly used for green tea, the dosage is not specified. Nutrient fortifier.
  2. Flavoring (the flavoring ingredient of green tea), the amount is not specified.
  3. Used as a food additive.
  4. An analog of glutamine, also an ingredient in green tea.

The sedative effect when added to food, the flavor improvement effect of L-theanine, enhances immunity, lowers blood pressure function, improves the brain, promotes the brain to learn and memory function, and effectively enhances liver detoxification function through the theanine antihypertensive effect.

What are the “Three Treasures” in tea?

History flows in teacups for thousands of years. Chinese people have never regarded tea as a simple drink, but as a “tea medicine,” that is beneficial to health. In the Tang Dynasty, there was a saying that “tea is the medicine for all diseases”, which was highly respected by later generations. Modern research has unlocked the mysteries of tea and uncovered “three great treasures”.

First treasure, tea tannins fight cancer. The bitter taste and astringency in tea come from tannins (tea polyphenols). It accounts for 40% – 60% of tea soluble composition. Tea tannin is the “number one contribution” to tea. First of all, it can resist oxidation, improve immunity, and prevent many cancers, including lung cancer, esophageal cancer, liver cancer, and colon cancer. Secondly, tea tannin can regulate blood lipids, and have the effect of reducing weight, and eliminating fat. Again, tea tannin can strengthen microvascular activity, and increase the absorption of nutrients. Finally, tea tannins also have the effect of lowering blood sugar and preventing smoking damage.

Number two, caffeine boosts you. Studies have found that tea leaves contain 8 to 10 percent caffeine in their soluble content. Caffeine can be a diuretic, accelerate the body’s waste discharge, but also stimulate the central nervous system, refreshing effect. In addition, it increases metabolism and promotes muscle contraction. However, the longer the tea brews, the more caffeine seeps out. People who sleep poorly, people with mood swings, pregnant women, and so on drink less is better.

The third treasure is theanine’s strong memory. Theanine is a special free amino acid in tea. It is what gives the tea its rich and sweet taste. Theanine was the most abundant in new tea and decreased with fermentation. Studies have found that theanine can significantly promote the release of central dopamine in the brain and improve the physiological activity of dopamine in the brain. So it can make people mentally happy, at the same time will enhance memory, and improve learning ability. In addition, theanine also has the effect of lowering blood pressure, calming emotions, and relieving physical and mental fatigue.
