Product Introduction

Our top quality L-Theanine Powder is made from the highest quality amino acid extraction method and uses only the finest green tea leaves (Camellia sinensis). This naturally occurring substance is purified by stringent purification methods at our state-of-the-art facilities to provide a white fine crystalline powder with standards of 10% to 99% purity confirmed by HPLC analysis. Unlike most green tea extracts, which contain a mixture of chemicals, our isolated constituent provides formulators with accurate dosing reliability for clean-label cognitive enhancing solutions.

Third-Party Test Report

Independent Testing: We perform extensive testing on all our material for every production lot through third-party labs like as SGS and Eurofins worldwide, providing complete transparency and quality control.

Purity Analysis: HPLC chromatography ensures the precise quantity of L-Theanine, differentiating our product from lower-grade extracts that may contain undesirable caffeine or catechin residues that can influence formulation outcomes.

Safety Screening: Comprehensive pesticide residue panels of over 400 compounds guarantee adherence to EU legislation (EC 396/2005) and US EPA standards, safeguarding your brand image.

Product Specification

Pure L-Theanine Powder Advantages

Pharmaceutical-Grade Purity: Advanced crystallisation process provides >98% purity that removes formulation irregularities so you can produce products with predictable efficacy and clean supplement facts panels consumers desire.

Superior Solubility Profile: Our Pure L-Theanine Powder dissolves entirely in cold and warm water, unlike other ingredients that leave cloudiness or sedimentation. This overcomes the difficult hurdle of producing clear functional beverages and ready-to-drink formats.

Taste-Neutral Characteristics: Our refined material is essentially devoid of flavour interference, unlike crude extracts which have residual bitterness due to polyphenols, offering your R&D team full flexibility of taste development.

Pure L-Theanine Powder Application

Stress Management Supplements: Capsules and tablets in the $19 billion stress management business, where this amino acid helps you relax without sleepiness like other medications.

Cognitive Performance Blends: Mix with caffeine in clinically supported ratios (2:1 L-Theanine to caffeine) to make pre-workout and nootropic blends that boost concentration without the jitters and energy crashes.

Functional Beverage Innovation: Add to ready-to-drink teas, enhanced waters and sports recovery beverages, tapping into the "calm energy" trend that's driving premium beverage development.

Production Process

Step 1 - Raw Material Selection: We procure quality green tea leaves from Shaanxi Province’s certified organic growing bases, and manage the harvest schedule to ensure optimal L-Theanine concentration.

Step 2 - Hot Water Extraction: Fresh leaves are extracted at controlled temperatures in stainless steel reactors. Undesired chemicals are separated, but sensitive amino acid structures are preserved.

Step 3 - Filtration and Clarification: The extract is passed through multi-stage filtration systems which remove particles and activated carbon treatment which removes colour and residual polyphenols.

Step 4 - Ion Exchange Chromatography: As the solution passes through special resin columns, L-Theanine separates from the other amino acids and carbohydrates because its unique chemical structure binds specifically to the resin.

Step 5 - Concentration and Crystallisation: The purified solution is concentrated by vacuum evaporation and cooled in a controlled manner to induce crystallisation of L-Theanine.

Step 6 - Drying and Milling: The crystals are dried in special low temperature vacuum dryers to remove residual moisture and then milled to exacting standards for a consistent 80 mesh particle size.

Step 7 - Quality Testing and Packaging: Each batch is subjected to a rigorous analysis in our SGS laboratory before being packed in double layer PE bags within fibre drums under regulated humidity conditions.

FAQ

Q: What is the difference between the product and green tea extract?

A: Green tea extracts are a mixture of chemicals such as catechins, caffeine, polyphenols and L-Theanine. In its pure form, we extract solely the L-Theanine molecule using chromatography, giving you exact dosing without the stimulating effects of caffeine or the astringency of polyphenols, excellent for targeted relaxation formulations.

Q: How do I know what dosage to use for supplement formulations?

A: For general stress management , clinical trials have shown 100-200mg to be beneficial , and 200-400mg is used in cognitive enhancement stacks ( frequently stacked with coffee ). We suggest you review relevant published studies about your particular claims and collaborate with qualified formulators.

Q: Is the activity of the powder reduced on tableting or encapsulation?

A: L-Theanine shows good stability in regular manufacturing settings. Tableting and short heat exposure during encapsulation do not appreciably affect potency, due to compression forces. We recommend not to keep the material over 60°C for long time and to control humidity during processing.
