Best L Theanine Powder

L-Theanine is a non-proteinogenic amino acid derived from Camellia sinensis, appearing as colorless, needle-like crystals (melting point: 217-218°C). It is highly water-soluble, yielding an aqueous solution with a caramel aroma and umami flavor, but remains insoluble in organic solvents such as ethanol and ether.

Zero D-Theanine Contamination: Precise enantiomeric control ensures a pure L-form (> 99.0%), eliminating the inactive D-enantiomer optical isomer to deliver maximum biological potency per milligram.

 

Crystal-Clear Liquid Dissolution: The powder dissolves completely in room-temperature water within seconds without haze, sediment, or precipitation, making it ideal for clear ready-to-drink (RTD) functional beverages.

 

Infant-Grade Safety Standards

Verified low limits for heavy metals, residual solvents, and microbial loads, meeting strict R&D requirements for infant nutrition and premium clinical supplements.

 

24–36 Month Shelf Life

Retains full chemical integrity within standard sealed, dry, and temperature-controlled warehouse conditions (15°C–25°C).

Custom Particle Sizing: We offer standard 80-mesh powder for general blending, coarse granules for advanced tableting compression, and ultra-fine 200-mesh micronized powder for rapid-dissolve instant beverage stick packs.

Functional Functional Premixes: Our cleanroom blending department can manufacture uniform, homogeneous active blends-combining L-Theanine with Caffeine, Vitamin B-Complex, or Melatonin-saving you labor steps during final production.

Turn-Key Dosage Form Customization: Through our OEM contract lines, we can deliver finished consumer products ready for retail, including custom-molded pectin/gelatin gummies, high-precision capsules, and compressed tablets.

Facility Accreditations: Certified under cGMP (NSF/USP standards), ISO 22000, and FSSC 22000 Food Safety Management Systems.

Comprehensive Documentation Package: Every shipment is accompanied by a full Certificate of Analysis (CoA), SDS, Allergen Statement, GMO Statement, and BSE/TSE-Free Certification.

Third-Party Validation: We partner with independent, ISO 17025 accredited laboratories (such as Eurofins or SGS) to perform routine third-party verification of purity, microbiological counts, and heavy metals.

1–3 kg: Double-layer, moisture-proof aluminum foil bags with heat-sealed closures.

1–20 kg: Sealed food-grade PE inner bags securely packed inside heavy-duty, double-wall corrugated master cartons.

10–30 kg: Food-grade HDPE plastic drums or fiber drums fitted with internal vacuum-sealed linings and moisture-absorbent desiccant packs.

Standard Items: Dispatch within 5 to 7 working days (leveraging our extensive off-the-shelf bulk ingredient inventory).

Nonstandard Items: Dispatch within 15 to 20 working days (including customized particle mesh sizing, specialized premixes/blends, or custom-labeled private packaging).

Global Logistics Support: We support standard international shipping terms including FOB, CIF, DAP, and DDP, coordinating with top-tier freight forwarders for temperature-controlled air cargo, ocean freight, or express courier services (DHL/FedEx/UPS).

Note: Actual dispatch timelines vary based on specific formulation requirements, custom mesh sizing, and total lot sizes.
