Shandong Fulibai Chem supplies bulk L-theanine powder from China for supplement brands, contract manufacturers and ingredient distributors. Our main supply option is fermentation-derived material, with samples and batch documentation available for review.
When sourcing L-theanine, buyers need to consider more than assay alone. Production route, impurity limits, microbiological specifications and performance in the finished formulation also matter. Send us your required specification, application and order quantity so we can confirm a suitable supply option.
Capsules, Tablets and Gummies
L-theanine can be considered for supplement formulations positioned around relaxation, sleep and focus. Samples are available for formulation trials and sensory evaluation.
Functional Beverages and Powdered Drink Mixes
For beverage projects, evaluate the ingredient at the intended use level in the complete formula. Check taste, clarity and stability under the planned processing and storage conditions.
Caffeine-Containing Formulations
For projects combining L-theanine with caffeine, tell us your ingredient specifications and intended product format. We can provide samples and a quotation for the required quantity.

Specification Review
We review your assay, impurity and microbiological requirements against the proposed grade before quotation.
Samples for Evaluation
Samples are available for your own formulation and quality checks before a bulk order.
Batch Documentation
A batch COA is available for review. Additional testing can be discussed when your specification includes requirements beyond the routine test panel.
Flexible Sourcing
Fermentation-derived L-theanine is our main offering. Chemically synthesized L-theanine and tea-derived options can also be sourced, with specifications and availability confirmed for each request.
Q1: What is the assay specification of your L-theanine powder?
Our main fermentation-derived grade has an assay specification of 98.0–102.0%. The batch COA records the result for the tested batch. If you require a different assay range or a specific test method, please send us your specification for review.
Q2: Do you supply fermentation-derived, synthetic and tea-derived L-theanine?
Yes. Fermentation-derived L-theanine is our main supply option. We can also source chemically synthesized L-theanine and tea-derived options. Please specify the production route and L-theanine content you need, as these options may have different compositions, specifications and prices.
Q3: Is your L-theanine suitable for a ready-to-drink beverage?
Suitability should be checked in your complete formulation. The specification includes a clear, colorless solution under the stated test conditions, but this does not establish the shelf stability of a finished beverage. We recommend sample trials at your intended concentration, pH and processing conditions.
Q4: Can I request a sample, COA or third-party testing?
Yes. Samples and a batch COA are available for evaluation. Third-party testing can be arranged upon request. Please provide the required test items and methods so that scope, cost and timing can be confirmed before testing.
