Theanine, chemically known as N-ethyl-γ-L-glutamine, is a characteristic non-protein amino acid of tea plant, which has only been reported in the mushroom (Xerocomus badius) and some Camellia sasanqua plants (Camellia japonica and Camellia sasanqua). Theanine is the main component of free amino acids in tea leaves, and it is believed that theanine accounts for about 70% of the total free amino acids in the new shoots and about 1-2% of the dry weight of tea leaves in the fresh leaves.
In 1950, Japanese scholar Yajiro Sakado isolated the main substance that produces this flavor from green tea - a non-protein amino acid, named theanine. All the theanine in tea is levorotatory, and according to the nomenclature is recorded as "L-theanine.
Since then, research has found that theanine not only brings fresh flavor to tea, it also has many physiological functions of its own. For example, it can break the blood-brain barrier and directly affect brain activity, thus having an impact on human emotions. In 1964, L-theanine was approved for use as a food additive in Japan, and in 1985, the U.S. FDA gave L-theanine a GRAS classification. GRAS means "Generally Recognized as Safe", which is not related to "health value", but means that it can be used freely in a variety of foods. Progress in China was slow until July 18, 2014, when the Health and Welfare Commission finally approved it as a new food ingredient.
1. Effect on central nervous system: theanine can obviously promote the release of dopamine in the brain center and improve the physiological activity of dopamine in the brain.
2. Antihypertensive effect: The study proved that theanine can effectively reduce spontaneous hypertension in rats. The theanine showed the effect of lowering hypertension can also be regarded as a kind of stabilizing effect to a certain extent. And this stabilizing effect will undoubtedly help the recovery of physical and mental fatigue.
3. Enhance memory, improve learning ability: research has found that theanine can significantly promote the central dopamine release in the brain and improve the physiological activity of dopamine in the brain. Therefore, it can make people happy, and at the same time will enhance memory and improve learning ability.
4. Calm down emotions and relieve physical and mental fatigue: the intake of theanine at different time periods can adjust the degree of balance between wakefulness and sleepiness and keep it at the appropriate level. Theanine will play a hypnotic role at night, and play a waking role during the day.
5. Protect nerve cells: theanine can inhibit the death of nerve cells caused by transient cerebral ischemia, and has a protective effect on nerve cells.
Theanine is suitable for: people who are under stress and easily fatigued at work; people who are emotionally stressed and anxious; people with memory loss; people with low physical fitness; menopausal women; people who are frequent smokers; people with high blood pressure; and people who do not sleep well.
