Product Introduction of L-Theanine
L-Theanine was first isolated from green tea in 1950. It is a characteristic amino acid of tea and one of the flavor substances in tea. It is strongly positively correlated with the quality of green tea, with a correlation coefficient of 0.787-0.876. Among the more than 20 types of amino acids present in tea, theanine accounts for approximately 50% to 60% of the total amino acid content in tea; Through research, it has been found that trace amounts have been detected in plants such as Camellia, mushrooms, and Camellia oleifera, but have not been found in other plants.
L-theanine has been shown to help reduce stress and anxiety by promoting relaxation. It increases the levels of GABA, serotonin, and dopamine in the brain, which can help improve mood and reduce stress levels.
Effects:
Relaxation and anti-anxiety: L-theanine can produce a relaxing effect without causing drowsiness, so it is often used to relieve stress, anxiety, and other conditions.
Improves cognitive function: When combined with caffeine, L-theanine can improve concentration and alertness, and reduce the restlessness caused by caffeine.
Improves sleep quality: Some studies have shown that L-theanine can help improve sleep quality, especially for people who are anxious or stressed.
Advantages of L-Theanine
Theanine is a unique free amino acid in tea, which has various effects, mainly including:
1. Antioxidant
Theanine contains abundant phenolic hydroxyl groups, which can effectively eliminate free radicals in the human body, prevent damage to human cells by free radicals, and thus play an antioxidant and anti-aging role.
2. Anti inflammatory effect
Theanine can inhibit some key enzymes in the inflammatory response, reduce the generation of inflammatory factors, and thus alleviate inflammation. For example, theanine can to some extent inhibit the growth and reproduction of Escherichia coli, achieving anti-inflammatory effects.
3. Antibacterial effect
Theanine can inhibit some common pathogenic bacteria, such as Staphylococcus aureus and Escherichia coli, and protect the human body from microbial invasion.
4. Boosting immunity
Theanine can enhance the body’s immune system, enhance resistance, reduce the risk of infection, and have a certain effect on preventing diseases such as colds and influenza.
5. Promoting central nervous system function
Theanine can stimulate the central nervous system, enhance the processing ability of the cerebral cortex to external stimuli, improve alertness, attention, etc., enhance thinking ability and memory. It also helps to improve blood circulation in the brain, increase oxygen supply to the brain, regulate the balance of neurotransmitters, and enhance the metabolic activity and resistance of brain cells.
6. Relieve stress and promote sleep
Theanine can promote the synthesis of dopamine and norepinephrine in the brain, helping to relieve stress and tension, and improve mental health levels. At the same time, it can also promote the synthesis of neurotransmitters in the brain, help improve sleep quality, alleviate insomnia and other problems.
7. Protecting the heart
Theanine can lower blood lipids, lower cholesterol, help prevent cardiovascular disease, and protect heart health.
8. Relieve physical fatigue
Theanine can activate inhibitory nerves in the brain, calm excitatory nerves, improve sleep quality, and thus alleviate the phenomenon of physical fatigue.
9. Protecting nerve cells
Theanine has a certain protective effect on nerve cells, which can temporarily inhibit brain cell death caused by cerebral ischemia and alleviate discomfort symptoms caused by elderly dementia.
10. Assisted antihypertensive therapy
Studies have shown that theanine has the effect of dilating blood vessels and can lower blood pressure, making it suitable for people with hypertension.
