Green tea extract total catechins
What is Green Tea catechins?
Green tea extract total catechins is a comprehensive polyphenol extract from Camellia sinensis leaves, standardized to deliver a defined total catechin content encompassing the four major catechins: EGCG, epicatechin, epigallocatechin, and epicatechin gallate.
Green tea is one of the most extensively studied botanicals in modern nutrition science, with thousands of publications documenting the antioxidant, metabolic, and wellness-supporting properties of its catechin polyphenols.
KH Health manufactures full-spectrum green tea extract, which is produced through controlled water-ethanol extraction from certified green tea leaf material, followed by careful standardization to achieve consistent total catechin content. Standardized by HPLC to total catechins 50-98% (EGCG + EGC + ECG + EC), with tea polyphenols 50-98% (UV) and decaffeinated grades from the same production line. Unlike suppliers who report a single assay number, every COA carries the complete catechin profile and declared caffeine content—the analytical depth that exposes adulteration and heat abuse. Because green tea extract is one of the most closely regulated botanicals in the EU, every batch document supports EFSA-compliant labeling, and third-party testing (Eurofins, SGS or your preferred lab) available.
Catechin Family Profile (Typical Natural Composition)
| # | Compound | CAS No. | Notes |
|---|---|---|---|
| 1 | (-)-Epigallocatechin gallate (EGCG) | 989-51-5 | Most abundant and most studied; the EFSA-regulated marker |
| 2 | (-)-Epigallocatechin (EGC) | 970-74-1 | Non-gallated; contributes antioxidant capacity |
| 3 | (-)-Epicatechin gallate (ECG) | 1257-08-5 | Gallated; strong antimicrobial signal in food systems |
| 4 | (-)-Epicatechin (EC) | 490-46-0 | The flavanol most linked to endothelial function research |

Product applications
Antioxidant & Anti-Aging Supplements
The antioxidant supplement market continues to expand as consumers seek evidence-based ingredients to combat oxidative stress and support healthy aging. Green tea catechins are among the most researched antioxidant polyphenols.
Green tea extract total catechins delivers a comprehensive polyphenol profile in compact capsules or tablets, typically combined with vitamin C, vitamin E, or resveratrol for synergistic antioxidant effects.
Weight Management & Metabolic Health
Weight-management supplements remain a high-demand category, with consumers increasingly seeking natural ingredients with clinical research support for metabolic health and healthy body composition.
Total catechins extract supports thermogenic and metabolic positioning in weight-management formulas, typically combined with caffeine, L-carnitine, or chromium picolinate in capsule or powder formats.
Functional Beverages & Food Applications
The functional beverage market is growing rapidly, with consumers seeking drinks that deliver more than hydration — particularly antioxidant and wellness benefits from recognizable natural ingredients like green tea.
Our total catechins extract is suitable for functional beverage, shot, and fortified food applications where water-soluble polyphenols and characteristic green tea flavor are desired. Custom particle sizes and solubility profiles are available.
customer case
Confidential — European Functional Beverage Brand
A European functional beverage brand developing a new antioxidant shot line needed a green tea extract total catechins supplier able to deliver consistent polyphenol content, clean flavor profile, and full food-grade documentation. After evaluating multiple suppliers, they selected our total catechins grade based on batch consistency, solubility characteristics, and comprehensive documentation.
Qualified as an approved supplier within four weeks
Scaled from a 200 kg trial to a quarterly bulk program of approximately [1000] kg
Total catechins content remained within specification across the first ten lots
Zero batch rejections and on-time delivery across the first year
Result: the antioxidant shot line launched successfully with green tea total catechins as a key differentiator, and the brand expanded to include a second flavor variant the following year.

Q:What is the difference between total catechins and EGCG?
Total catechins refers to the combined content of all four major green tea catechins: EGCG, EC, EGC, and ECG. An EGCG-standardized extract focuses on a single catechin, while a total catechins extract delivers the full spectrum. Some formulators prefer total catechins for broad-spectrum antioxidant applications, while others choose EGCG for targeted metabolic or weight-management positioning. We offer both specifications.
Q:What applications use green tea extract total catechins?
Green tea extract total catechins is used in antioxidant and anti-aging supplements, weight-management and metabolic health products, general wellness and longevity formulas, and functional beverages. The full-spectrum catechin profile supports broad antioxidant positioning and is particularly valued in applications where the synergistic effects of multiple catechins are desired.
Q:What documents and certifications do you provide?
Each batch ships with a COA covering total catechins by HPLC, individual catechin profile (EGCG, EC, EGC, ECG), heavy metals, and microbiology. Our facility holds FSSC 22000 certification with Kosher, Halal, and SC programs. Non-GMO declarations, allergen statements, and stability summaries are available for your registration files.
Q:What is the green tea extract total catechins price and minimum order?
Green tea extract total catechins price per kg depends on the total catechin specification, order volume, and destination. Standard bulk MOQ is 25 kg with evaluation samples from 500 g. Lead time is typically 10 to 15 working days after confirmation of order details. Contact us for a tailored quotation.
Q: Is your product decaffeinated? What is the caffeine content?
Our conventional product caffeine residue is ≤0.5%, which is low caffeine grade and meets the requirements of most health care and cosmetic formulas. We can also provide zero-caffeine decaffeinated green tea extract according to customer customized needs.
Q: Do you ship internationally?
Yes. We serve customers in over 80 countries, supported by our U.S. subsidiary for local logistics. Standard export packing uses double-layered thickened PE bags inside fiber drums; in the rare event of transit damage, replacement goods are reshipped promptly.
Q: Do you offer OEM/ODM and custom formulation services?
Yes. With over 15 years of experience in plant extraction, we provide OEM/ODM services covering capsules, tablets, gummies, powder blends and private-label solutions for the food, supplement and cosmetics industries. Our formulation team can advise on dose positioning, caffeine-free formulation strategy and stability.
