Liposomal Green Tea Extract Powder
GMP-certified industrial-scale production of liposomal green tea extract powder. Camellia sinensis polyphenols encapsulated in non-GMO sunflower phospholipid bilayers for verified bioavailability enhancement. Two commercial specifications available — 50% and 70% active loading — with HPLC quantification, DLS particle size analysis, and encapsulation efficiency (EE%) verification per batch. Production-ready, document-complete ingredient for supplement manufacturers, sports nutrition brands, and functional beverage developers seeking scalable botanical actives.
Specifications

Liposomal Technology
Green tea catechins, particularly EGCG, are among the most potent botanical antioxidants — yet standard oral powders deliver only 12–25% absolute bioavailability. Our phospholipid bilayer encapsulation addresses this bottleneck at the delivery-system level.
The Absorption Problem
Standard green tea extract delivers only 12–25% of its EGCG into systemic circulation. Catechins degrade in the alkaline small intestine, undergo rapid phase II metabolism in the liver, and their hydrophilic nature limits passive diffusion across intestinal epithelial cells. For B2B buyers formulating high-performance supplements, this is a critical bottleneck: adding more extract to the capsule does not linearly improve bioavailability.
The Liposomal Solution — Phospholipid Bilayer Encapsulation
We encapsulate green tea polyphenols within nanoscale phospholipid vesicles formed from non-GMO sunflower lecithin. This bilayer simultaneously serves three critical functions: (1) physically shields catechins from gastric acid and intestinal alkaline degradation, preserving the active payload through the digestive tract; (2) fuses directly with intestinal epithelial cell membranes, bypassing passive diffusion and enabling cytoplasmic delivery; (3) provides sustained release as liposomes gradually degrade in circulation, extending the window of therapeutic plasma concentration. The result is significantly higher bioavailability versus conventional extracts — verified per batch by the three parameters below.
Active Loading
Weight percentage of active tea polyphenols in the total liposomal powder. 50% or 70% specification determines your formulation inclusion rate. Higher loading means fewer excipients, smaller capsule size, and more design flexibility for high-potency products.
Encapsulation Efficiency (EE%)
Percentage of active ingredient actually inside liposomes versus free in the powder. Our standard: ≥70%. EE% below 50% means you are purchasing mostly unencapsulated powder at a liposomal price. Verified by HPLC per batch.
Particle Size (DLS)
Mean vesicle diameter of 100–300 nm measured by dynamic light scattering. Vesicles above 500 nm are rapidly cleared by the reticuloendothelial system; below 50 nm have reduced payload capacity. Our range optimizes both circulation time and active loading.

Function & Mechanism
Standardized biochemical mechanisms of EGCG — validated active, quantifiable endpoints, reproducible batch performance for industrial formulation.
Radical Scavenging
EGCG's gallate moiety and multiple hydroxyl groups donate hydrogen atoms to neutralize ROS. Quantified antioxidant capacity: 25–100× that of vitamin C on a molar basis. HPLC-verified EGCG content provides a direct, standardizable proxy for antioxidant potency in batch QC.
Thermogenesis & COMT Inhibition
EGCG + naturally co-occurring caffeine inhibit COMT, extending norepinephrine activity. Documented 4–5% increase in 24-h energy expenditure at 300–400 mg EGCG. Dose-dependent, reproducible, non-stimulant mechanism for metabolic support formulations.
Endothelial Function
eNOS activation promotes vasodilation and healthy blood flow. Liver lipid metabolism modulation improves LDL/HDL ratio. Validated by flow-mediated dilation (FMD) and serum lipid profile improvements in controlled trials. Measurable, documentable endpoints.
Nrf2 Pathway Activation
Dual mechanism: direct ROS neutralization plus endogenous antioxidant defense upregulation via Nrf2/ARE pathway. Upregulates SOD, catalase, and glutathione peroxidase expression. Differentiates green tea from single-pathway antioxidant ingredients for comprehensive formulations.
