Green Tea Extract Epicatechin 90%
What is Green EC (epicatechin)?
Green tea extract EC (epicatechin) is a specialized catechin fraction from Camellia sinensis leaves, standardized to deliver a defined epicatechin content for precision formulation in muscle support, antioxidant, and cardiovascular health products.
Epicatechin is one of the four major catechins in green tea, alongside epigallocatechin gallate (EGCG), epigallocatechin (EGC), and epicatechin gallate (ECG). Epicatechin has emerged as a distinct active of interest for its potential role in supporting muscle growth, nitric oxide production, and insulin sensitivity. Our EC-standardized extract is produced through controlled extraction and fractionation to concentrate this specific catechin while maintaining the natural polyphenol matrix of green tea.

Product strength
Precision Catechin Standardization
Standardized epicatechin content by HPLC ensures every batch delivers the target active dose, enabling precise capsule and tablet formulation without guesswork.
Muscle Support Positioning
Epicatechin's emerging reputation in sports nutrition for supporting muscle growth and nitric oxide modulation gives brands a differentiated story in the crowded pre-workout and muscle-building categories.
Antioxidant Foundation
As a green tea catechin, epicatechin contributes to the well-established antioxidant profile of green tea polyphenols, supporting broader wellness and longevity positioning.
Low-Caffeine Option
Low-caffeine and decaffeinated versions are available for brands targeting caffeine-sensitive consumers or evening-use formulations.
Dual EC + EGCG Portfolio
Combine with our EGCG-standardized extract to offer a complete green tea catechin line, covering both muscle support and antioxidant applications.
Product applications
Sports Nutrition & Muscle Support Supplements
The sports nutrition market continues to grow, with consumers seeking evidence-based ingredients that support muscle growth, recovery, and performance beyond basic protein supplementation.
Green tea extract EC delivers a standardized epicatechin dose in compact capsules or powder blends, suitable for pre-workout formulas, muscle-building stacks, and recovery products.
Antioxidant & Longevity Formulations
Antioxidant supplements remain a cornerstone of the wellness market, with consumers increasingly seeking polyphenol-rich ingredients with documented bioactivity rather than generic antioxidant blends.
Green tea extract EC contributes to the total polyphenol content of antioxidant formulas, complementing other actives such as resveratrol, quercetin, and vitamin C in capsule, tablet, or liquid formats.
Cardiovascular & Metabolic Health Products
Cardiovascular and metabolic health supplements represent a mature but evolving category, with growing interest in polyphenol-based approaches that support vascular function and glucose metabolism.
Epicatechin's potential role in supporting nitric oxide production and insulin sensitivity makes it a candidate ingredient for heart-health and metabolic support formulations, typically combined with CoQ10, omega-3, or berberine.

customer case
A North American sports nutrition brand developing a new muscle-support line needed a green tea extract EC supplier able to deliver consistent epicatechin content and support transparent label claims. After evaluating COA data from multiple suppliers, they selected our EC-standardized grade based on HPLC verification and batch-to-batch consistency.
Qualified as an approved supplier within three weeks
The muscle-support capsule line launched successfully with epicatechin as a key differentiator, and the brand expanded the line to include a stacked EC+EGCG formula the following year.

Q:What is green tea extract EC (epicatechin)?
A:Green tea extract EC (epicatechin) is a standardized extract from Camellia sinensis leaves, specifically enriched for epicatechin (EC), one of the major catechins in green tea. Epicatechin is a flavan-3-ol polyphenol that has been studied for its potential role in supporting muscle growth, cardiovascular health, and antioxidant activity. Unlike broader green tea extracts, an EC-standardized product delivers a defined epicatechin content for precise formulation.
Q:What is the difference between epicatechin and EGCG?
A:Epicatechin (EC) and epigallocatechin gallate (EGCG) are both catechins found in green tea, but they differ in chemical structure and biological activity. EGCG is the most abundant and widely studied green tea catechin, known for potent antioxidant and metabolic effects. Epicatechin has gained attention for its potential role in muscle support and nitric oxide modulation. Some formulators prefer EC for muscle-health applications, while EGCG is favored for antioxidant and weight-management formulas. We offer both standardized extracts.
Q: What applications use green tea extract EC?
A:Green tea extract EC is used in sports nutrition and muscle-support supplements, antioxidant and longevity formulas, cardiovascular health products, and general wellness supplements. It is particularly popular in pre-workout and muscle-building formulations where epicatechin's potential role in supporting follistatin and muscle growth is of interest.
Q: What documents and certifications do you provide?
A:Each batch ships with a COA covering epicatechin content by HPLC, total catechins, 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 EC price and minimum order?
A:Green tea extract EC price per kg depends on the epicatechin 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.
