High Bioavailability Liposomal L-Theanine Powder Green Tea Extract Liposome Bulk Raw Material Supply
LIPOSOMAL
L-THEANINE POWDER (70%)
Liposomal L-Theanine Powder delivers 70% active L-Theanine (CAS 3081-61-6) encapsulated within a phospholipid bilayer via industrial emulsification and spray-drying. This free-flowing powder integrates directly into capsule, tablet, powder blend, and functional beverage premix production lines. A reliable B2B ingredient for manufacturers serving the global relaxation, focus, and sleep-support supplement markets.
TECHNICAL SPECIFICATIONS
LIPOSOMAL DELIVERY PRINCIPLE
L-Theanine is highly water-soluble, so liposomal encapsulation here targets controlled release and process compatibility rather than solubility enhancement. Unencapsulated L-Theanine dissolves rapidly in aqueous systems, causing uneven powder blend distribution and hygroscopicity-driven clumping during storage.
Our process embeds L-Theanine within phospholipid bilayer vesicles via controlled high-shear emulsification, then converts the preparation into a free-flowing powder by spray-drying. Key production benefits: (1) improved blend homogeneity in V-blender operations; (2) moisture resistance under standard warehouse conditions; (3) extended compatibility with multi-phase beverage systems for consistent per-batch dosing.

QUALITY VERIFICATION
1. HPLC Active Assay
Every batch tested to confirm 70% L-Theanine loading. Batch-specific CoA provided with each shipment.
2. DLS Particle Size Analysis
Verifies stable liposome formation (80–250nm) upon rehydration — consistent nano-scale vesicle dimensions across every production run.
3. Encapsulation Efficiency (EE%)
EE% ≥ 85% confirms genuine encapsulation within the liposome structure, not simple physical blending with phospholipids.
4. Heavy Metal & Microbial Screening
Full compliance: Pb ≤10ppm, As/Cd ≤1ppm, Hg ≤0.1ppm; TPC & Yeast/Mold per USP standards.
FUNCTIONAL ROLES
1. Relaxation Without Sedation
Promotes calm, relaxed alertness via alpha-brainwave activity — without drowsiness. A high-demand daytime relaxation active with strong repeat-purchase market dynamics.
2. Focus & Cognitive Performance
Widely paired with caffeine in nootropic formulations. Smooths stimulant edge while supporting sustained focus — a consistent B2B demand driver for functional beverage and supplement brands.
3. Sleep Quality Support
Supports sleep quality by promoting a relaxed pre-sleep state without direct sedation. Popular co-active alongside melatonin and magnesium in evening formulations.
4. Stress Management
Supports a balanced physiological response to everyday mental stressors. Staple ingredient across the growing stress-management and adaptogenic supplement categories.
INDUSTRIAL APPLICATIONS
1. Bulk Capsule Manufacturing
200–400mg single-active or multi-ingredient cognitive/relaxation complexes; excellent flowability for high-speed capsule filling lines.
2. Functional Beverage Premixes
Dry premix formats for stick packs, sachets, and bulk drink mixes. Liposomal carrier supports uniform dispersion upon reconstitution.
3. Tablet & Caplet Production
Compatible with direct-compression and wet-granulation. Standalone L-Theanine or multi-active stress-relief and focus tablet formulas.
4. OEM / Private Label Formulas
Ready-to-encapsulate or blend for cognitive wellness, stress-management, and sleep-support private-label supplement lines.

TECHNICAL FAQ
Q1: What is the monthly production capacity for bulk liposomal L-Theanine orders?
Our line supports multi-ton monthly output. For capacity allocation, lead times, and volume pricing, please contact our sales team with your projected annual requirements.
Q2: Can you customize the L-Theanine loading percentage?
Yes. Custom specs (e.g., 50%, 85%) are available for qualified large-volume OEM projects. MOQ and development lead times apply.
Q3: How is batch-to-batch consistency verified?
Every batch undergoes HPLC assay (target: 70%) with batch-specific CoA upon shipment. EE% and DLS particle size are monitored as routine QC across every production run.
