Applications
Where this ingredient fits
Use this when… — practical formulation guidance for each downstream application.
Antioxidant supplement formulas
Supplement brands and capsule/tablet manufacturers
Use TP98/EGCG50 or TP60/EGCG30 when the formula needs a high-marker green tea active with COA and HPLC support.
Functional beverage and solid drink powder
Functional food, beverage powder and sachet teams
Use TP50 instant when price, solubility, color, taste and dispersibility matter more than an EGCG-led claim.
Oral-care and cosmetic antioxidant
Cosmetic, oral-care and personal-care raw material buyers
Use tea polyphenol grades as botanical antioxidant inputs where final application and compliance route must be reviewed.
Weight-management and metabolic support
Sports nutrition and weight-management brands
Use EGCG-led grades in thermogenic and metabolic-support blends at clinically relevant serving sizes.

What is Green Tea Extract / Tea Polyphenols?
Green tea extract is a concentrated preparation made from the leaves of Camellia sinensis, the tea plant. The key bioactive group is the tea polyphenols — a family of catechins that includes epigallocatechin gallate (EGCG), epicatechin (EC), epigallocatechin (EGC) and epicatechin gallate (ECG). Standardized extracts typically report Tea Polyphenols 50-98% by UV and EGCG 30-50% by HPLC. Unlike a simple tea powder, an extract delivers a consistent, measurable dose of these actives, which is why supplement, beverage and cosmetic formulators prefer it over ground leaf.
EGCG and the polyphenol complex — why markers matter
EGCG is the most studied catechin and the usual marker for premium green tea extracts. However, the polyphenol profile is broader: a 'Tea Polyphenols 98% / EGCG 50%' grade means 98% total polyphenols and roughly 50% EGCG. Some suppliers inflate the polyphenol number by including non-catechin compounds, so professional buyers cross-check with HPLC. We report both UV (total polyphenols) and HPLC (EGCG) so you can compare batch-to-batch consistency and verify that the high polyphenol figure is backed by real catechin content.
How green tea extract is produced
Production starts with freshly plucked young tea leaves. After a quick heat-fixation step (pan-firing or steaming) to inactivate polyphenol oxidase and preserve green catechins, the leaves are dried and sent for extraction. The industrial extract uses aqueous ethanol, followed by membrane filtration, concentration and spray drying to produce a fine powder. Higher-EGCG grades may include additional purification. The result is a stable, standardized powder with known polyphenol and EGCG content, ready for capsules, beverage premixes or cosmetic actives.
Applications across supplements, food and cosmetics
Green tea extract's versatility comes from its antioxidant, metabolic and antimicrobial properties. In supplements it is used in antioxidant, weight-management and metabolic-support formulas, typically dosed at 200-500 mg per serving. In functional foods and beverages it adds an antioxidant claim and a subtle tea note, with instant grades designed for sachets and RTD drinks. In cosmetics and oral care, polyphenols provide antioxidant, soothing and sebum-regulating benefits for serums, creams, masks and toothpaste. Each application demands different specifications: supplements need EGCG confirmation, beverages need solubility and taste, cosmetics need color stability and low odor.
Antioxidant mechanism and health-positioning notes
Green tea polyphenols, especially EGCG, are potent antioxidants that scavenge free radicals and modulate cellular signaling pathways. This underpins the ingredient's use in anti-aging, immune-support and metabolic-health products. Formulators should note that EGCG is relatively unstable at high pH and in the presence of oxygen and metal ions, so formulation pH, packaging and storage matter. Health claims must follow destination-market regulations — for example, EFSA has strict rules on green tea catechin claims and hepatotoxicity warnings for high-dose supplements in the EU.
Quality, compliance and what to confirm before export
Before exporting, confirm the grade matches the application: food-grade, supplement-grade or cosmetic-grade. Check caffeine content (and whether decaffeinated is needed), pesticide residues against EU / US / Japan positive lists, heavy metals, PAHs, residual solvents and microbiology. Halal, Kosher and organic certifications should be reviewed per buyer market. US supplement buyers typically need cGMP and FDA facility documentation; EU buyers need compliance with food-supplement and novel-food rules. We prepare the document set per destination and review it during RFQ, with batch-specific COA and HPLC chromatograms on request.

Sourcing Story
From harvest to your formulation
Zhejiang, Guizhou and Sichuan tea regions, China
GreenSource™ Verified Origin
Green tea extract is produced from the young leaves of Camellia sinensis, the same species that yields the world's great green teas. We source from the cool, misty tea regions of Zhejiang (home of Longjing), Guizhou (high-elevation mountain gardens) and Sichuan (bamboo-terraced early-spring tea), where the spring flush delivers the highest catechin and EGCG concentration. Within hours of plucking, the leaves undergo fixation to preserve green polyphenols, then travel to extraction facilities for aqueous ethanol extraction and spray drying. Our GreenSource™ program links each batch to its sourcing region, tests every lot for polyphenols and EGCG by UV/HPLC, and works with cooperatives that support year-round livelihoods for smallholder tea farmers.
