L-Theanine is a unique non-protein amino acid derived from green tea. It has become a popular functional raw material for stress relief, sleep support and focus-support dietary formulas, with steadily growing global market demand.

2. Core Quality Advantages of Export-Grade L-Theanine

2.1 Stable Batch Indicators to Reduce Production Loss

Ordinary L-Theanine on the market tends to have yellowish color, uneven fineness and unstable solubility. It increases formula adjustment costs and even leads to finished product scrapping.
Our export-grade L-Theanine is produced under standardized quality control. Whiteness, content and solubility stay consistent for every batch. It resists caking and moisture absorption during long-term storage, lowering production waste and end-user complaints.

2.2 Stable Quality for Transoceanic Shipment

Packed in 25kg standard export fiber drums with moisture-proof and oxygen barrier design. Suitable for 3–6 months ocean transportation. It hardly oxidizes or turns yellow under high temperature and high humidity, ensuring all indicators meet requirements after arriving at overseas factories.

2.3 Compliant with Regulations Worldwide to Avoid Customs Risks

Food-grade L-Theanine is safe without prohibited additives. It complies with food raw material standards in the US, EU, Southeast Asia and other regions. It can be legally used in dietary supplements, functional beverages and solid food, effectively reducing risks of cargo detention and product removal.

2.4 Excellent Water Solubility for Automated Mass Production

It dissolves rapidly in cold water to form clear solution without sediment or stratification. Compatible with most product forms including capsules, tablets, powder blends, oral liquids and functional beverages, lowering processing difficulty for factories.

2.5 Pure Natural Flavor Fits the Clean Label Trend

Mild odor, slightly sweet without bitter taste. As a natural characteristic amino acid from green tea, it meets the global trend of natural, organic and clean-label products, helping brands launch high-premium calming dietary goods.

3. Main Overseas Application Fields of L-Theanine

With high safety and mild properties, L-Theanine is widely adopted in many popular overseas product lines:
✅ Calming capsules & powder for stress relief & mood support
✅ Sleep-support complex nutritional supplements
✅ Focus nutrition products for students & office workers
✅ Functional tea drinks, anti-stress sparkling beverages, sports recovery drinks
