Product Overview
Green Tea EGCG Powder is a standardized green tea extract commonly sourced for supplement, functional food, beverage, and other formulation projects requiring a defined EGCG content.
It is typically supplied in different EGCG specifications, including mainstream 50% EGCG and higher-purity options such as 98%, and buyers often review EGCG assay, HPLC basis, total polyphenols, catechin profile, and caffeine level before technical or commercial evaluation.
It is commonly considered for capsules, tablets, powder blends, functional beverages, and other EGCG-focused formulations, with specification matching, evaluation samples, technical documentation, and bulk supply support available for sourcing projects.

Applications
Dietary Supplements
Suitable for capsule, tablet, and powder supplement projects that require an EGCG-focused green tea extract rather than a broader polyphenol or catechin route.
Functional Food & Active Blends
Suitable for active-focused food systems and powder blends where a concentrated EGCG route supports the formulation concept more directly than a wider green tea extract page.
Targeted Formulation Projects
Can be considered for narrower tea-active formulation systems where buyers want a more defined EGCG direction for product planning and specification review.
How to Choose the Right Grade / Form
EGCG Target
Green Tea Extract is commercially available with different EGCG concentrations according to formulation and sourcing requirements. 50% EGCG is a common concentrated specification, while higher-purity grades such as 98% EGCG may be selected when a more targeted EGCG profile is required.
Broader Extract Profile
For 50% EGCG and other standardized green tea extracts, buyers should also review total polyphenols, total catechins, caffeine, color, taste, and other extract characteristics. These parameters may be less relevant to highly purified EGCG grades, where purity and impurity profile become more important.
Caffeine Requirement
Caffeine content should be confirmed separately from EGCG assay. Low-caffeine or caffeine-controlled requirements may be important for supplement, beverage, and specialty formulation projects.
Analytical Basis
EGCG values should be compared using the same agreed analytical method and specification basis. HPLC is commonly used for EGCG determination, and samples and commercial batches should be evaluated consistently.
Technical & Formulation Notes
Technical Notes
This product is usually reviewed on an EGCG-focused assay basis rather than as a broad green tea polyphenol route or a wider catechin-focused extract direction.
Commercial evaluation typically centers on EGCG positioning, purity direction, and intended application target.
Manufacturing & Process
Green Tea EGCG is generally supplied as a concentrated green tea extract prepared for ingredient use where EGCG-rich positioning is part of the commercial requirement.
Process review usually focuses on extract consistency, active-direction suitability, and handling compatibility for the intended dosage or formulation system.
Compatibility / Formulation Notes
For capsules and tablets
Review flow behavior, powder uniformity, and compatibility with the intended excipient system before confirming the specification for solid dosage use.
For powder blends / sachets
Check blend compatibility, moisture sensitivity, and taste impact when the extract is used in multi-ingredient powder systems.
For active-focused systems
Pilot testing is recommended when the finished concept depends on a concentrated EGCG route, especially where handling behavior or formulation balance may affect the final system.
Storage / handling notes
Protect the material from moisture, direct light, and prolonged open-air exposure during handling and repacking.
Extended QC & Test Items
QC review may include appearance, active-content basis, caffeine-related checks, moisture-related control items, and agreed specification items according to the selected product route.

FAQ
What EGCG specifications are available?
Green Tea EGCG Powder can be supplied with different EGCG targets according to formulation and commercial requirements. 50% EGCG is a common standardized extract specification, while 98% EGCG represents a higher-purity option for projects requiring a more concentrated EGCG profile. Final availability should be confirmed according to the required specification and order quantity.
What is the difference between 50% EGCG and 98% EGCG?
A 50% EGCG specification is typically a concentrated green tea extract that may still contain a broader profile of polyphenols and catechins, while 98% EGCG is a much more purified EGCG-focused ingredient. Buyers should select the appropriate route according to formulation goals, purity requirements, caffeine limits, sensory considerations, and commercial positioning.
Is 50% EGCG the same as 50% total polyphenols?
No. EGCG is one specific catechin, while total polyphenols represent a broader group of compounds in green tea extract. Two materials may have similar EGCG content but different total polyphenol, catechin, and caffeine profiles, so these parameters should be reviewed separately.
How is EGCG content tested?
EGCG is commonly determined by HPLC. When comparing suppliers, buyers should confirm that the quoted specification, evaluation sample, and commercial batch are assessed using the same agreed analytical method and specification basis.
How should caffeine be reviewed in Green Tea EGCG Powder?
Caffeine should be treated as a separate specification parameter from EGCG. Low-caffeine or caffeine-controlled limits may be important for supplement, beverage, and specialty formulation projects, so the required caffeine level should be confirmed together with EGCG, total catechins, and total polyphenols before supplier approval.
Is Green Tea EGCG Powder suitable for beverages and functional formulations?
Yes, suitable EGCG specifications may be considered for beverage, RTD, powder blend, supplement, and other functional formulation projects. Formulators should review dispersibility, clarity, flavor impact, pH, processing temperature, caffeine level, extract profile, and finished-product stability before commercial scale-up.
What should buyers check when comparing EGCG suppliers?
Buyers should review EGCG assay together with the analytical method, total polyphenols, total catechins, caffeine, moisture, heavy metals, pesticide residues, microbiological limits, application requirements, and batch documentation. A higher EGCG percentage alone does not necessarily mean the material is the best fit for every project.
What documents and samples can Lifeworth provide?
Evaluation samples can be arranged for specification review and formulation testing. Available support may include COA, TDS, SDS, EGCG assay information, caffeine specification, packaging details, and other technical or quality documents according to the selected product and sourcing requirement.
