Green Tea Extract L-Theanine

Green Tea Extract L-Theanine is a natural, standardised botanical extract derived from the leaves of Camellia sinensis. Its core value lies in the precise enrichment and quantification of L-theanine, a characteristic non-protein amino acid sourced from premium green tea (Camellia sinensis). Green Tea Extract L-Theanine is a unique amino acid recognised for its pronounced calming effects, aiding relaxation and enhancing focus without inducing drowsiness. Unlike conventional green tea extracts primarily focused on tea polyphenols or EGCG, APPCHEM employs precise extraction and purification processes to isolate and refine L-theanine from green tea. This ensures a high-purity, functionally defined L-theanine for the dietary supplement market.

Green Tea Extract L-Theanine is typically supplied in powder or liquid form and finds extensive application across various functional foods, beverages, and health products. With growing attention on health and mental well-being, Green Tea Extract L-Theanine has emerged as a popular natural ingredient with substantial market potential.

XI'AN APP-CHEM BIO (TECH) CO., LTD. (APPCHEM) provides Green Tea Extract L-Theanine utilising a mature, reproducible industrial plant extraction process, comprising the following principal steps:

1. Washing
2. Filtering
3. Removing impurities
4. Drying: to prevent high-temperature damage to thermosensitive active ingredients, especially volatile oils.
5. Crushing: (such as 80 mesh) to increase the contact area with the solvent and improve extraction efficiency.
6. Extraction
7. Solid-liquid separation
8. Purification
9. Concentrate
10. Drying
11. Smashing
12. Packaging
13. Finished product

The unique value of Green Tea Extract L-Theanine lies in its ability to cross the blood-brain barrier and directly act upon the central nervous system, thereby exerting its diverse physiological effects. Its mechanism of action is complex and sophisticated, primarily involving the regulation of brainwave activity and key neurotransmitter systems.

• Promoting Relaxation

Green Tea Extract L-Theanine's most widely recognised effect is inducing a state of 'alert relaxation'. Unlike traditional sedatives, it significantly alleviates mental tension and anxiety without inducing drowsiness.

• Enhancing Cognitive Function

As a potent nootropic compound, Green Tea Extract L-Theanine demonstrates considerable potential for enhancing cognitive performance, particularly in domains such as attention, executive function, and memory. As a structural analogue of glutamate, L-theanine exerts precise modulation over both excitatory (glutamate) and inhibitory (GABA) neurotransmitter systems within the brain. Research indicates that Green Tea Extract L-Theanine also increases levels of monoamine neurotransmitters in the brain associated with attention, motivation, and mood, such as dopamine and serotonin. Elevated dopamine levels are closely linked to improved working memory and executive function, while increased serotonin helps enhance mood and reduce anxiety's occupation of cognitive resources.

• Alleviating Stress and Improving Sleep Quality

Green Tea Extract L-Theanine effectively combats physiological and psychological stress, indirectly improving sleep quality. Consuming Green Tea Extract L-Theanine reduces heart rate and blood pressure during stressful states while decreasing secretion of the stress hormone cortisol. Alleviating anxiety and promoting relaxation before bedtime facilitates entry into deep sleep, thereby enhancing sleep efficiency and quality. Users awaken feeling more energised, without the "hangover effect" associated with traditional sleeping pills.
