Product Overview
Green Tea Polyphenols Powder is a standardized green tea extract commonly sourced for supplement, functional food, beverage, and premix applications requiring a defined total-polyphenol content.
It is typically supplied in multiple concentration grades, including 50% total polyphenols and higher-concentration options such as 90%, 95%, and 98%, and buyers often review total polyphenols together with catechins, EGCG, caffeine, color, and analytical basis before technical or commercial evaluation.
It is commonly considered for capsules, tablets, powder blends, functional beverages, and other green tea extract formulations, with specification matching, evaluation samples, technical documentation, and bulk supply support available for sourcing projects.
Applications
Dietary Supplements
Green Tea Polyphenols Powder is commonly considered for capsules, tablets, sachets, stick packs, and nutritional blends requiring a standardized green tea extract. Buyers should select the total-polyphenol concentration according to formulation design, dosage format, and finished-product positioning.
Functional Food & Powder Blends
Standardized Green Tea Polyphenols may be incorporated into functional food, powder, and premix systems. Color, taste, extract concentration, and compatibility with other botanical or nutritional ingredients should be evaluated during formulation development.
Beverage & RTD Applications
For beverage and RTD systems, formulators should review dispersibility, clarity, flavor contribution, pH, processing temperature, caffeine content, catechin profile, and finished-product stability before commercial scale-up.
Multi-Ingredient Functional Formulations
Green Tea Polyphenols Powder may also be used in multi-active formulations together with botanicals, amino acids, vitamins, minerals, or other functional ingredients. The selected extract grade should be evaluated according to the complete formulation system rather than total-polyphenol percentage alone.
How to Choose the Right Grade / Form
Total Polyphenol Level
Green Tea Polyphenols Powder may be supplied with different total-polyphenol targets according to formulation and sourcing requirements. 50% is a common standardized extract specification, while higher-concentration grades such as 90%, 95%, and 98% may be selected when a more concentrated polyphenol profile is required.
Catechin & EGCG Background
Total polyphenols should not be evaluated alone. Buyers may also review total catechins and EGCG because materials with the same total-polyphenol percentage can have different catechin distributions and formulation characteristics.
Caffeine Requirement
Caffeine content should be reviewed separately from total polyphenols. Low-caffeine or caffeine-controlled requirements may be important for supplement, beverage, and functional formulation projects.
Analytical Basis & Application Fit
The stated total-polyphenol percentage should be reviewed together with the analytical method, extract composition, color, taste, solubility or dispersibility, and intended dosage form. Supplier quotations and commercial batches should be compared using the same agreed specification basis.
Technical & Formulation Notes
Technical Notes
Green Tea Polyphenols Powder should be evaluated primarily according to total-polyphenol assay, but this value should not be reviewed in isolation. Buyers may also compare total catechins, EGCG background, caffeine, color, and other extract characteristics because materials with the same total-polyphenol percentage may have different overall profiles.
Manufacturing & Process
Green tea polyphenol extracts are produced through extraction, concentration, purification, and drying steps designed to obtain a standardized polyphenol profile. Purification intensity and processing conditions may vary according to the required total-polyphenol concentration, catechin composition, caffeine target, and commercial specification.
Compatibility / Formulation Notes
Capsules & Tablets
For capsules and tablets, review particle characteristics, flowability, bulk density, moisture condition, and blend uniformity together with the selected total-polyphenol concentration.
Powder Blends & Premixes
For sachets, stick packs, and powder blends, color, taste, dispersion behavior, moisture exposure, and compatibility with other ingredients should be evaluated during pilot testing.
Beverages & Liquid Systems
Higher-concentration polyphenol extracts may behave differently from mainstream standardized grades in terms of color, taste, clarity, and dispersibility. Beverage projects should therefore evaluate the selected grade under actual pH, processing, flavor, and storage conditions.
Processing & Stability
Processing temperature, pH, oxygen exposure, moisture, and storage conditions may influence extract performance. Technical qualification should be based on the selected specification and intended finished-product system.
Extended QC & Test Items
Technical evaluation may include total polyphenols, total catechins, EGCG, caffeine, moisture, heavy metals, pesticide residues, microbiological limits, and other agreed quality parameters. Batch COA and supporting technical documents should be reviewed against the approved purchasing specification before commercial supply.

FAQ
What total polyphenol specifications are available?
Green Tea Polyphenols Powder can be supplied with different total-polyphenol targets according to formulation and commercial requirements. 50% total polyphenols is a common standardized extract specification, while higher-concentration options such as 90%, 95%, and 98% may be selected for projects requiring a more concentrated polyphenol profile.
What is the difference between Green Tea Polyphenols, Catechins, and EGCG?
Green tea polyphenols represent a broad group of compounds in green tea extract. Catechins are an important subgroup of these polyphenols, while EGCG is one individual catechin. Buyers should therefore review total polyphenols, total catechins, and EGCG as separate but related specification parameters.
Is 50% total polyphenols the same as 50% catechins or 50% EGCG?
No. Total polyphenols, total catechins, and EGCG measure different parts of the green tea extract profile. A material standardized to 50% total polyphenols should not be assumed to contain 50% catechins or 50% EGCG unless those values are separately specified.
How should caffeine be reviewed in Green Tea Polyphenols Powder?
Caffeine should be treated as a separate specification parameter from total polyphenols. Low-caffeine or caffeine-controlled requirements may be important for supplement, beverage, and functional formulation projects and should be confirmed before supplier approval.
How are Green Tea Polyphenols tested?
The analytical basis depends on the target parameter. Total polyphenols may be evaluated using an agreed total-polyphenol method, while individual catechins and EGCG are commonly reviewed by HPLC where applicable. Buyers should compare samples and commercial batches using the same agreed test basis.
Is Green Tea Polyphenols Powder suitable for beverages?
Suitable grades may be considered for beverage and RTD applications. Formulators should evaluate dispersibility, color, flavor impact, pH, processing temperature, caffeine level, catechin profile, and finished-product stability before commercial scale-up.
What should buyers check when comparing Green Tea Polyphenols suppliers?
Buyers should compare total-polyphenol assay together with analytical basis, catechin and EGCG profile, caffeine, moisture, heavy metals, pesticide residues, microbiological limits, application requirements, and batch documentation rather than relying on the headline polyphenol percentage alone.
Can Lifeworth provide samples and technical documents?
Yes. Evaluation samples can be arranged for specification review and formulation testing. Available support may include COA, TDS, SDS, assay information, packaging details, and other technical or quality documents according to the selected specification.
