L-Theanine Powder | 3081-61-6
Product Description:
Theanine (L-Theanine) is a unique free amino acid in tea leaves, and theanine is glutamic acid gamma-ethylamide, which has a sweet taste. The content of theanine varies with the variety and location of the tea. Theanine accounts for 1-2 by weight in dry tea.
Theanine is similar in chemical structure to glutamine and glutamic acid, which are active substances in the brain, and is the main ingredient in tea.L-Theanine is a flavoring.
Theanine is the amino acid with the highest content in tea, accounting for more than 50% of the total free amino acids and 1%-2% of the dry weight of tea. Theanine is white needle-like body, easily soluble in water. It has a sweet and refreshing taste and is a component of the taste of tea.
The efficacy of L-Theanine Powder CAS:3081-61-6: Used in the treatment of depression
Theanine has been used in the treatment of depression, the most common mental illness in the world.
Protect nerve cells
Theanine can inhibit nerve cell death caused by transient cerebral ischemia, and has a protective effect on nerve cells. The death of nerve cells is closely related to the excitatory neurotransmitter glutamate.
Enhance the efficacy of anticancer drugs
Cancer morbidity and mortality remain high, and drugs developed to treat cancer often have strong side effects. In cancer treatment, in addition to the use of anticancer drugs, a variety of drugs that suppress their side effects must be used at the same time.
Theanine itself has no anti-tumor activity, but it can improve the activity of various anti-tumor drugs.
Sedative effect
Caffeine is a well-known stimulant, yet people feel relaxed, calm, and in a good mood when they drink tea. It has been confirmed that this is mainly the effect of theanine.
Regulate changes in neurotransmitters in the brain
Theanine affects the metabolism and release of neurotransmitters such as dopamine in the brain, and brain diseases controlled by these neurotransmitters may also be regulated or prevented.
Improve learning ability and memory
In animal experiments, it was also found that the learning ability and memory of the mice taking theanine were better than those of the control group.
Improve menstrual syndrome
Most women have menstrual syndrome. Menstrual syndrome is a symptom of mental and physical discomfort in women aged 25-45 in the 3-10 days before menstruation.
The sedative effect of theanine brings to mind its ameliorating effect on menstrual syndrome, which has been demonstrated in clinical trials on women.
The effect of lowering blood pressure
Theanine may lower blood pressure by regulating the concentration of neurotransmitters in the brain.
Anti-fatigue effect
L-theanine has anti-fatigue effects. The mechanism may be related to that theanine can inhibit the secretion of serotonin and promote the secretion of catecholamine (serotonin has an inhibitory effect on the central nervous system, while catecholamine has an excitatory effect), but its mechanism of action remains to be further explored.
Removal of smoking addiction and removal of heavy metals in smoke
The research team led by Zhao Baolu, a researcher from the State Key Laboratory of Brain and Cognition, Institute of Biophysics, Chinese Academy of Sciences, discovered last year that theanine, a new substance that inhibits tobacco and nicotine addiction, achieves the effect of eliminating smoking addiction by regulating the release of nicotine receptors and dopamine. Later, it was recently found that it has a significant scavenging effect on heavy metals including arsenic, cadmium and lead in smog.
Weight loss effect
As we all know, drinking tea has the effect of losing weight. Drinking tea for a long time makes people thin and removes people's fat.
In addition, theanine has also been found to have liver protection and antioxidant effects.
