茶氨酸的作用和功效：
- 改善经期综合症
经期综合症(简称PMS)是女性在月经期间出现精神及身体上不舒适症状。表现为头痛、腰痛、胸部胀痛、无力、易疲劳、精神无法集中、烦躁等症状。
茶氨酸是茶叶中特有的一种游离氨酸。茶叶中生津润甜成分就是它。它可以促进脑中枢多巴胺释放，提高脑内多巴胺生理活性，多巴胺有助于减轻工作压力，缓和疲劳的症状。茶氨酸的镇静作用对经期综合症有改善作用。
- 天然抑菌
中国农业科学院在茶叶功能性成分利用与安全性评价研究方面取得重要进展。该团队利用茶氨酸设计合成了一种新型的铜团簇抗菌剂，可以有效地清除多种耐药菌感染并且具有良好的生物安全性。早在1985年，美国食品和药物管理局（FDA）就认可茶氨酸，并确认合成茶氨酸是一般公认安全物质（GRAS），在使用过程中不作限量规定。
本项目研究不仅仅是单一的茶叶功能性成分的简单利用，而是一个非常大胆的创新，设计并创制了一个新材料。以茶叶功能性成分为核心，围绕茶叶中氨基酸等功能性物质，研发新材料，发挥了茶叶功能性成分安全、可靠，容易代谢等特点，这是新材料研发与新药评价与应用的前提。
- 祛味
茶氨酸的活性成分能够有效祛味。
- 缓解疲劳、镇静安神、改善睡眠。
茶氨酸和安眠药都能通过加强大脑中GABA（氨基丁酸）的作用，能够缓解疲劳、镇静安神、改善睡眠；不一样的是茶氨酸即使白天摄取也不会令人昏昏欲睡。
Action and efficacy of theanine:
1.Improvement of the menstrual syndrome
Menstrural syndrome (PMS) is a symptom of mental and physical discomfort in women during menstruation. The symptoms are headache, low back pain, chest pain, weakness, easy fatigue, mental inability to concentrate, irritability and other symptoms.
Theanine is a free ammonia acid unique to tea leaves. It is the moist and sweet ingredient in tea. It can promote the release of dopamine, improve the physiological activity of dopamine in the brain, dopamine helps to reduce work pressure and relieve the symptoms of fatigue. The sedative effect of theanine ameliorates the menstrual syndrome.
2.Natural bacteriostatic
The Chinese Academy of Agricultural Sciences has made important progress in the utilization and safety evaluation of tea functional ingredients. The team used theanine to design and synthesize a new copper cluster antibacterial agent, which can effectively eliminate a variety of drug-resistant bacteria infections and has a good biological safety. As early as 1985, the US Food and Drug Administration (FDA) recognized theanine and confirmed that theanine is a generally recognized safety substance (GRAS) and is not limited during use.
This project is not just a simple use of a single functional ingredient of tea, but a very bold innovation, designing and creating a new material. Taking the functional ingredients of tea as the core, new materials are developed around the functional substances such as amino acids in tea, giving full play to the characteristics of safe, reliable and easy metabolism of tea functional ingredients, which is the premise for the research and development of new materials and the evaluation and application of new drugs.
3.Dissolve the taste
The active ingredient of theanine can effectively dispel taste.
4.Relieve fatigue, calm down, and improve sleep.
Both theanine and sleeping pills can relieve fatigue, calm, and improve sleep by strengthening the effects of GABA (aminobutyric acid) in the brain; unlike theanine is not drowsy even during the day.
