THE BUYER'S GUIDE / SELECTION
Choosing L Theanine Green Tea Extract Plant Extract Raw Material Wholesale: Application Fit and Specification Checks
This guide helps procurement teams and formulators evaluate l theanine green tea extract as a bulk raw material. It explains what the specification sheet discloses, how to match those confirmed parameters to common application categories, and which quality checkpoints matter most before placing a wholesale order with Hebei Finutra Biotech Co., Ltd.
L-Theanine assay (≥ 20% by HPLC) must match the inclusion rate required to achieve the target label claim at the intended serving size.
Caffeine content (≤ 2.0% by HPLC) must be evaluated against formulation goals and regional caffeine-disclosure thresholds, particularly for sleep-support, relaxation, or caffeine-sensitive-consumer products.
What Is L Theanine Green Tea Extract?
L theanine green tea extract is a plant-derived amino acid ingredient sourced from the leaves of Camellia sinensis. L-Theanine is found in several plant and mushroom species but is particularly abundant in green tea. It possesses a unique savory, umami flavour profile and is commonly used to moderate the bitterness of certain food and beverage formulations. Buyers evaluating this ingredient for wholesale use should focus on the confirmed specification data rather than generalised marketing claims.
Hebei Finutra Biotech Co., Ltd. offers an L Theanine Green Tea Extract as a plant extract raw material in bulk quantities.

Selection Criteria for Procurement Teams
1. Matching the L-Theanine Assay to Your Application Dose
The confirmed L-Theanine assay is ≥ 20% by HPLC. Before committing to a wholesale volume, formulators should calculate the raw-material inclusion rate needed to hit their target label claim. A 20% assay means that for every gram of extract used, at least 200 mg is L-Theanine. Applications requiring higher L-Theanine concentrations per unit will need proportionally larger inclusion rates; confirm whether a ≥ 20% grade meets your dose economics before ordering.
2. Caffeine Level and Low-Stimulant or Sleep-Support Formulas
The specification caps caffeine at ≤ 2.0% by HPLC. For formulators developing sleep-support supplements, relaxation blends, or products marketed to caffeine-sensitive consumers, this low caffeine ceiling is a critical suitability checkpoint. Verify that ≤ 2.0% caffeine is acceptable under your regional labelling rules and any caffeine-disclosure thresholds before finalising your sourcing decision.
3. Physical Form and Dispersibility
The material is a yellow-brown powder at 95% pass 80 mesh. This particle size is relevant for capsule filling, sachet blending, and direct-compression tablet processes. Buyers working with fine-particle encapsulation or premix blending should confirm that 80-mesh suitability aligns with their manufacturing equipment tolerances.
4. Microbiological and Heavy-Metal Compliance Verification
The specification documents total plate count, mould/yeast counts, pathogen absence (E. coli, Salmonella) and four individual heavy-metal limits against USP 34 and EP 7.0 methods. Procurement teams supplying US, EU, Middle Eastern or Southeast Asian markets should compare these limits against applicable local ingredient standards and request the most recent batch certificate of analysis (CoA) to confirm lot-specific compliance.
5. Stability, Packing and Storage Fit
Shelf life is 24 months when stored cool, dry, and away from direct sunlight in the original sealed 25 kg drum. Buyers should assess whether their warehouse conditions and projected consumption rate match this window. If your facility cannot maintain appropriate storage conditions or if batch turnover extends beyond 24 months, additional stability risk assessment is warranted.
Application Fit Assessment
Based on the confirmed specification data, green tea extract l theanine in this grade is broadly suited to the following wholesale application categories:
- Dietary supplements – capsules, tablets, softgels, and powder sticks targeting mood support, sleep quality, focus, and cognitive function, where the ≥ 20% assay and low caffeine content support label claims consistent with product documentation.
- Functional food and beverage – l theanine and green tea extract are noted to have an umami flavour profile that can moderate bitterness; relevant for functional teas, ready-to-drink beverages, and fortified food formats that can accommodate a yellow-brown powder.
- Nutraceutical premixes – the standardised assay and documented microbiological limits make this grade usable in contract-manufactured premix formulations where consistent input quality is required.
- Cosmeceutical R&D – the non-GMO and BSE/TSE-free status, together with heavy-metal limits, may satisfy basic input-material screening for topical or ingestible cosmeceutical development; however, buyers must verify applicable regulatory classifications in their target market independently.
Applications requiring higher L-Theanine purity (e.g., above 20%), a different particle size, or specific solvent-extraction documentation should confirm with Hebei Finutra Biotech Co., Ltd. whether alternative grades or customised specifications are available before ordering.
Key Specification Checkpoints Before You Order
Procurement teams should complete the following verification steps with any wholesale l theanine green tea extract supplier, including Hebei Finutra Biotech Co., Ltd.:
- Request the current batch CoA – confirm that lot-specific results for L-Theanine assay, caffeine, heavy metals and microbiological counts are within the published specification limits.
- Confirm non-irradiation compliance – the specification declares non-irradiation (≤ 700 per EN 13751:2002); verify this aligns with your market's import requirements.
- Verify non-GMO and BSE/TSE-free status documentation – obtain supplier-issued documentation if your finished-product labelling or retailer requirements mandate it.
- Check residual solvent compliance – the spec states "Meet USP Requirements"; request the specific solvents list and corresponding residual limits if your formulation or market demands explicit disclosure.
- Align storage conditions – confirm the 24-month shelf life is achievable under your actual storage conditions and planned throughput.
