Direct-from-manufacturer bio-compounds, mushroom adaptogens, and high-purity functional food powders shipped directly to Khanh Hoa and throughout Vietnam.
For nutraceutical brand owners and R&D directors in Nha Trang and the wider Khanh Hoa region, sourcing biologically active L-Theanine (N-ethyl-L-glutamine, CAS: 3081-61-6) requires strict adherence to enantiomeric differentiation. While synthetic racemates often contain D-theanine—which exhibits non-uniform neurological affinity and regulatory complications—our green tea-derived and biosynthesized L-theanine delivers guaranteed 100% optical purity without residual solvent contaminants.

How Khanh Hoa's wellness resorts, premier hospitality chains, and functional beverage manufacturers exploit L-Theanine's unique neurological mechanism.
Nha Trang's coastal hospitality ecosystem utilizes ultra-fine 100-mesh L-theanine powder for luxury resort mocktails and ready-to-drink sparkling botanical elixirs. Offering zero turbidity, it interacts synergistically with natural fruit acids (like our spray-dried orange juice powder) without sour degradation, generating sustained alpha-wave brain activity for vacation relaxation without sedation.
Leveraging Vietnam's Central Highlands Robusta supply chain intersecting through Khanh Hoa logistics corridors, local brands combine high-caffeine espresso bases with our HPLC ≥99% L-theanine at a calibrated 1:2 ratio (100mg caffeine to 200mg theanine). This blunts vasoconstrictive jitters, stabilizes blood pressure, and delivers peak cognitive stamina desired by digital nomads residing in coastal Nha Trang.
Contract dietary supplement packagers serving international tourists across Khanh Hoa blend pharmaceutical-grade L-Theanine with GABA, magnesium bisglycinate, and our standardized organic mushroom mycelia. The non-hypnotic down-regulation of glutamate receptors eases sensory overstimulation caused by tropical flight travel, facilitating restorative REM sleep without next-day grogginess.
Khanh Hoa province is transitioning from purely leisure tourism into a premier biotech and holistic health epicenter. The domestic demand for clean-label, plant-based anti-stress solutions has surged following national health initiatives, with green tea extracts leading the category due to culturally rooted trust in Camellia sinensis heritage.
Eliminating intermediate broker markups with verifiable factory credentials, robust supply security, and full-spectrum documentation.
Operating a modernized 12,447 m² extraction complex in Xi'an with 89 technical staff. Direct access to our extraction tanks, vacuum evaporators, and spray towers ensures full supply security and consistent lot-to-lot homogeneity.
In-house quality validation featuring liquid chromatography (HPLC), gas chromatography (GC), and atomic absorption spectrophotometry (AAS). Every single shipment arrives with verified batch COA, heavy metal panel, and residual solvent clearance.
17+ years of international export prowess. We offer low-MOQ pilot batches (from 1kg for formulation trials) up to full multi-ton container loads with expedited customs dossiers (Form E, Certificate of Origin, Phyto certificates) for seamless entry into Vietnam.
Addressing legal clearance, optical purity validation, storage stability in coastal humidity, and contract manufacturing terms.
L-Theanine is mildly hygroscopic. For tropical marine environments like Khanh Hoa, Torzi Biotech ships product in double-layer virgin pharmaceutical polyethylene internal liners heat-sealed inside aluminum foil vacuum barrier pouches, housed within heavy-duty fiber drums with silica dessicants. When stored unbreached below 25°C and <60% RH, powder stability is guaranteed for 24 months.
Yes. Our ingredients strictly comply with Circular No. 24/2019/TT-BYT and QCVN regulations for dietary supplements and food additives. Every batch exported to Vietnam is accompanied by full compositional COA, heavy metal testing (Pb <0.5ppm, As <0.3ppm, Cd <0.1ppm, Hg <0.1ppm), microbiology assays, non-GMO statements, and allergen declaration documentation.
Natural green tea extraction yields 100% L-isomer, but natural extraction yields typically range from 1% to 2% in dry leaves, making it costlier. Synthetic routes may risk toxic precursors if ethylamine residues remain unreacted. Torzi provides both high-yield enzymatically converted (biocatalytic) and purely isolated tea-derived grades, both tested via Chiral HPLC to guarantee zero biologically inert D-Theanine.
Standard trial orders start as low as 1 kg to 5 kg for pilot R&D formulations. Commercial drums are packaged at 25 kg net weight. Air freight via Cam Ranh International Airport (CXR) typically delivers within 4 to 6 business days from dispatch, while sea container consignments via Cam Ranh Port or Cat Lai take approximately 12 to 14 days door-to-door.
