L-Theanine 40% – Premium Plant Extract Ingredient for Formulations

1. Product Introduction

Natural L-theanine Extracted From Tea refers to the process of obtaining this specific amino acid directly from the leaves of the tea plant, Camellia Sinensis. L-theanine is unique in that it is the only amino acid found in significant quantities in tea, and it plays a crucial role in giving the tea its distinct flavor profile, contributing to the umami taste sensation. Our extraction process is designed to preserve the integrity of this amino acid while ensuring that it can be effectively concentrated for use in various applications
The final product is a white crystalline powder that can be easily incorporated into a variety of formulations, such as dietary supplements, functional beverages, and even certain food products.
Theanine is a unique free amino acid in tea, and theanine is glutamic acid γ-ethylamine. Theanine content varies with the variety and location of tea. Theanine accounts for 1% to 2% of dry tea. Theanine is a white needle, soluble in water. With a sweet and refreshing taste, is the taste of tea components.

Raw Material & Extraction Foundation
The foundation of our L-Theanine 40% ingredient lies in the careful selection of raw materials and precise extraction technology. Only young and mature green tea leaves grown in pesticide-controlled environments are selected, ensuring a naturally high concentration of L-theanine while minimizing contaminants. These leaves are gently processed through a proprietary water-based extraction system that isolates L-theanine from the broader green tea extract matrix. Unlike synthetic or chemically modified versions, this process preserves the amino acid’s natural configuration and accompanying phytonutrients that enhance absorption and synergy. The extraction involves aqueous filtration, purification, and controlled drying, yielding a fine, free-flowing powder with uniform particle size and excellent solubility. Our production team, backed by decades of experience as plant extract manufacturers, ensures full traceability and batch consistency—from field to final packaging. Every stage, from sourcing to quality assurance, adheres to international GMP standards, demonstrating our reliability as a global plant extract supplier.

Functional Performance & Formulation Integration
L-theanine has long been recognized as a key component associated with green tea extract and green tea leaf extract, and is valued for its calming, cognitive-focus and mood-support attributes (subject to local regulatory claim allowances). As a high-concentration extract, this ingredient provides a reliable base for dosage design, enabling brands to deliver functional benefits while maintaining clean-label messaging. The L-Theanine 40% ingredient integrates easily into capsules, tablets, drink powders, beverage concentrates, fortified foods and wellness blends. Its botanical source — green tea leaf extract — supports value propositions such as “plant-based amino acid”, “derived from green tea extract” and “natural botanical origin”. As a plant extract supplier we provide documentation (COA, certificate of origin, heavy metal and microbial testing) and support for OEM/ODM clients. Because it is produced by a seasoned plant extract manufacturer, the product benefits from stringent quality systems, consistent batch-to-batch performance and supply reliability. This reliability is crucial when scaling formulations, launching private-label lines or exporting globally.

Quality Control & Manufacturing Strength
Quality assurance is central to this ingredient’s value. Every production batch is tested and verified using advanced analytical instruments such as HPLC, GC, TLC and UV spectrophotometry to confirm content, purity and identity. Comprehensive microbial testing, heavy-metal screening and moisture control are conducted to ensure the product meets international quality standards. Our role as a plant extract supplier extends beyond manufacturing to include full technical support—providing Certificates of Analysis, Material Safety Data Sheets, origin verification and compliance documentation tailored to your regulatory market. The facility’s infrastructure, featuring modern extraction lines and clean-room environments, allows us to maintain batch uniformity and scale up production to meet both small and large-volume needs. As reliable plant extract manufacturers, we also manage logistics, export documentation and OEM/ODM customization, ensuring that every client receives both technical precision and flexible service.
