L-Theanine represents nature's answer to modern cognitive wellness challenges. This unique amino acid naturally crosses the blood-brain barrier to promote alpha brain wave activity without sedation.
Green Tea Theanine Powder offers a clean-label solution that addresses consumer demand for plant-based nootropics. Unlike synthetic alternatives, our water-extracted ingredient preserves the full phytochemical profile of green tea while concentrating therapeutic compounds.
The extract provides manufacturers with flexible formulation options. You can choose standardized concentrations from 20% to 60% theanine content based on your product's positioning and target dosage requirements.

Choice of Superior Raw Materials: Tea leaves are grown in restricted growth areas with strict pesticide monitoring procedures to ensure pure botanical inputs before extraction.
High-Activity Standardisation: Our patented extraction procedure concentrates L-Theanine and maintains thermal stability (121°C for 30 min). The heat resistance is compatible with a wide range of production methods such as spray drying and tablet compression.
Contaminant Control Solutions Our innovative purification technologies may improve your formulations. We provide customised pesticide residue removal, plasticiser removal and reduced caffeine variations for sensitive customer sectors.
Multi-Gradient Customisation: Whether you need 20% standardisation for cost-effective functional meals or 60% concentration for premium cognitive supplements, our versatile manufacturing capabilities are customised to meet your individual requirements.
Consistent Batch Bioactivity Profiles: Supported by Nrf2-centric research databases and PhD-led quality control, each batch maintains consistent bioactivity profiles. This dependability decreases your formulation change expenses and speeds your time-to-market.

Functional Beverages Due to the high water solubility of the powder, it is perfect for ready-to-drink formulations. Develop clear liquid formulations with cold-water soluble grades to provide calm-focus advantages without cloudiness.
Dietary Supplements: Sold as capsules, pills or soft gels targeting the stress management, sleep quality or cognitive performance markets. The tiny particle size provides good mixing in complicated multi-component matrices.
Sports Nutrition: Combine with natural sources of caffeine in synergistic pre-workout combinations. Theanine smooths the jitters of caffeine but yet keeps you awake – a solution to the energy-without-anxiety problem customers want.
Cosmetic Formulations: Incorporate the ingredient’s antioxidant capabilities into topical skincare formulations. Its thermal resilience allows it to be used in emulsions and hot industrial processes.
Functional Food Products: Incorporate plant-based nootropic properties into protein bars, energy snacks, or fortified confections to appeal to health-conscious consumers.
As a professional developer of targeted nutritional intervention technologies, we leverage rigorous scientific research to deliver high-quality, science-backed ingredient solutions for global clients.
The research team has proprietary databases covering six major molecular signalling pathways including Nrf2 activation mechanisms relevant to oxidative stress management. This knowledge translates into the better choice of raw materials and extraction optimisation.
Our manufacturing partners are GMP, ISO22000, HACCP and HALAL certified. Each batch is subjected to extensive testing beyond the minimum parameters which include testing for pesticide residues (EC 396/2005) and testing for solvent residues (Gas Chromatography).
You receive full traceability documentation to support regulatory filings in multiple markets. We provide compliance help on rules on China New Food Raw Materials, US FDA frameworks and European nutraceutical directives.

Q:What is the actual difference between total polyphenols, catechins and EGCG?
A:Among plant polyphenols, EGCG of the catechin subclass is the most clinically useful compound for metabolism support. Product is about L-Theanine concentration, but this distinction helps formulators combine complementary green tea extracts. To ensure therapeutic efficacy, the quantification of a specific active ingredient, rather than total polyphenol quantification, needs to be confirmed.
Q:Will the product be guaranteed to meet verified specifications?
A:Yeah, absolutely. We promise your produced items will match your approved samples completely. All batches are tested strictly before shipping and meet the Chinese, European or US Pharmacopoeia requirements. Your quality expectations are always fulfilled in all orders.
Q:Does this extract include caffeine?
A:Natural green tea extracts often contain 2-10% caffeine. We offer bespoke solutions to meet your formulation demands – from conventional caffeine levels for energy applications to decaffeinated versions (<0.5%) for night-time goods or caffeine-sensitive populations. State your needs throughout the ordering procedure.
Q:How does this compare to synthetic L-Theanine?
A:Plant-derived theanine maintains the natural L-isomer configuration with specific rotation between +7.7° to +8.5°, distinguishing it from inactive D-isomers sometimes present in synthetic production. Natural extraction preserves minor phytochemicals that may contribute to bioavailability, though both forms demonstrate clinical efficacy.
Q:What minimum order quantities apply?
A:Contact our team for current MOQ information and volume-based pricing structures. We accommodate both established brands requiring container loads and emerging companies testing formulation concepts with smaller initial purchases.
