Green Tea Extract EGCG 50%
What is Green Tea EGCG?
Green tea EGCG (epigallocatechin gallate, CAS 989-51-5, molecular formula C22H18O11) is the most abundant and biologically studied catechin in green tea, belonging to the tea polyphenol and green tea catechin family found in Camellia sinensis leaves. KH Health supplies it as a fine bulk powder standardized to 50% EGCG by HPLC. It is the mainstream mid-to-high potency EGCG raw material for global functional health products and cosmetic formulations, but we can also provide 98% EGCG,It is produced from fresh tea leaves through water and ethanol extraction followed by column purification. The catechin structure gives EGCG strong free-radical scavenging activity, and it remains one of the most requested green tea extract actives for dietary supplements worldwide.
As a green tea extract supplier and manufacturer, KH Health controls quality from leaf intake to finished powder. Unstandardized tea polyphenols vary naturally with harvest and origin; our 50% grade fixes the active marker so formulators can dose reproducibly batch after batch. Each lot ships with a certificate of analysis covering assay, caffeine, residual solvents, heavy metals, and microbiology, and the powder blends cleanly into capsules, tablets, stick packs, beverages, and cosmetic bases. KH Health is an FSSC 22000, Kosher, Halal, and SC certified facility in Xi'an, Shaanxi, China.

Product benefits
Potent Antioxidant Support
EGCG is a well-studied free-radical scavenger among green tea catechins, supporting the body's natural antioxidant defense and cellular protection pathways.
Metabolism & Energy Balance
Research interest in tea polyphenols includes thermogenesis and normal energy metabolism support, making EGCG a staple active in weight-management and slimming formulas.
Cardiovascular Wellness
EGCG's antioxidant and vascular-support profile positions it well in heart-health and healthy-circulation supplement concepts for mainstream retail.
Product applications
1. Antioxidant & Metabolism Capsules and Tablets
The antioxidant supplement market is crowded, and buyers increasingly demand high-potency, verifiable actives rather than generic polyphenol powders with no marker assay.
EGCG 98% bulk powder delivers a concentrated, measurable catechin dose per capsule; 50% grade suits lower-strength tablets and premixes at better cost efficiency.
2. Functional Beverages & Tea Drinks
Functional tea and RTD brands want the authenticity of tea polyphenols with stable dosing, clean taste, and reproducible solubility batch after batch.
The fine powder disperses in water-based systems and dry tea blends; decaffeinated grade supports evening and caffeine-sensitive formats.
3. Sports Nutrition & Daily Wellness Sticks
Active-lifestyle consumers pair antioxidant support with training and metabolic goals, driving growth in pre-workout and recovery powder formats.
EGCG stacks cleanly with vitamin C, L-carnitine, and green tea extract combinations in stick packs, effervescent tablets, and shakes.

Skincare and ingestible-beauty brands are adopting tea polyphenols for their antioxidant and skin-supporting reputation in serums, creams, and beauty powders.

customer case
Confidential — European Nutraceutical Brand
A European nutraceutical brand building an antioxidant and metabolism line switched its green tea sourcing from an unstandardized tea polyphenol to our EGCG 98% grade after struggling with batch variation. The fixed HPLC marker simplified their COA review and let them cut serving size while keeping label strength, and the decaffeinated option opened an evening format. The brand now places recurring quarterly orders and has extended EGCG into a sports-nutrition stick pack.

Q:Why buy green tea EGCG bulk powder from KH Health?
A:KH Health is an integrated green tea extract manufacturer and supplier based in Xi'an, China. Our EGCG 50% bulk powder is standardized by HPLC from Camellia sinensis leaves and produced in an FSSC 22000 certified facility under GMP control. Every batch ships with a certificate of analysis covering assay, caffeine, heavy metals, and microbiology, giving formulators a consistent and fully traceable raw material.
Q:What is the difference between EGCG 50% and EGCG 98%?
A:Both grades start from the same green tea extract, but EGCG 98% undergoes extra purification steps to concentrate epigallocatechin gallate, so a smaller capsule delivers a higher active dose. The 50% grade is more economical for tea drinks, premixes, and everyday antioxidant products. We supply either grade on request with the same per-batch COA documentation.
Q:Do you provide a COA and third-party test report with each batch?
A:Yes. Every production lot is released with a certificate of analysis that includes EGCG and total catechin assay by HPLC, loss on drying, residual solvents, heavy metals, and microbiology such as total plate count, yeast and mold, E. coli, and Salmonella. Independent third-party testing can be arranged through an accredited laboratory on request, and retained samples are kept for three years.
Q: Is your 50% EGCG water-soluble? Will there be precipitation in liquid products?
A:Our product is specially water-soluble treated, with water solubility ≥5mg/ml. It can be completely dissolved in normal temperature and hot water systems, no precipitation and stratification after long-term placement, fully suitable for beverage and liquid finished product production.
Q: Do you support decaf grade 50% EGCG? What is the caffeine content?
A:Yes, we provide optional decaf grade, conventional grade caffeine ≤1.0%, decaf grade caffeine ≤0.5%, which can meet the production requirements of low-caffeine and caffeine-free health products and skincare products.
Q: What is your MOQ and bulk price discount policy?
A:The minimum order quantity is 25kg. Long-term bulk procurement has hierarchical discount policies, and we provide exclusive quotation and price protection services for regular cooperative customers. You can contact us to get the latest factory wholesale price.
Q: How to guarantee the batch stability of EGCG content?
A:We adopt standardized HPLC fixed detection process and fixed production parameters. The batch-to-batch error of EGCG content is controlled within 2%, and each batch is issued with a professional COA test report to ensure consistent product quality.
Q: What is the storage method and shelf life of the product?
A:Seal and store in a cool, dry and ventilated environment, avoid high temperature and direct sunlight. The shelf life is 24 months under standard storage conditions, and the active ingredient content remains stable within the shelf life.
