Standardized Botanical Ingredient for Supplements, Foods & Cosmetics
Hero Section
Tea polyphenols are naturally occurring botanical compounds derived from tea leaves (Camellia sinensis). In commercial manufacturing, they are valued not for consumer-facing claims, but for their well-characterized polyphenol profile, antioxidant capacity at the ingredient level, and formulation flexibility across multiple industries.
AIHerba® supplies standardized tea polyphenols extract for bulk sourcing and OEM/ODM manufacturing, supporting supplement brands, food producers, cosmetic formulators, and contract manufacturers that require consistent specifications, documented quality, and reliable long-term supply.
Our focus is not on marketing claims, but on manufacturing control, regulatory alignment, and batch-to-batch consistency—the factors that matter most to professional buyers.

What Are Tea Polyphenols?
Tea polyphenols are a group of naturally occurring polyphenolic compounds present in tea leaves. They primarily include catechins, such as epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), and epicatechin (EC).
These compounds are among the most extensively studied plant polyphenols in food and nutrition science, largely because tea has been consumed globally for centuries and its chemical composition is well documented.
From a manufacturing perspective, standardized tea polyphenols extract differs from whole green tea extract. While green tea extract may contain caffeine, amino acids, and other native components, standardized tea polyphenols focus on:
- Defined total polyphenol content
- Reduced natural variability
- Improved suitability for industrial formulation and quality control
This distinction is particularly important for brands and factories operating under strict specification and compliance requirements.

Why Choose Standardized Tea Polyphenols for Manufacturing?
For product developers and procurement teams, consistency matters more than claims.
Standardized tea polyphenols are commonly selected as a raw material because they support:
- Controlled total polyphenol content, simplifying dosage and formulation design
- Improved batch-to-batch consistency, critical for scale-up and repeat production
- Reduced variability compared to unstandardized botanical powders
- Clear documentation, supporting internal QA review and regulatory evaluation
Standardization helps manufacturers manage risk, streamline quality control, and maintain stable product performance across production cycles.
Applications Across Multiple Industries
Dietary Supplements
Tea polyphenols are widely used in capsules, tablets, and powder blends where botanical sourcing and antioxidant positioning are required. Standardized grades allow formulators to design products with predictable ingredient contribution.
Functional Foods & Beverages
In food and beverage manufacturing, tea polyphenols are incorporated into functional drinks, nutrition powders, and fortified foods. Selection criteria typically focus on solubility, taste impact, stability, and regulatory compliance.
Cosmetics & Personal Care
In cosmetic formulations, tea polyphenols are used for their antioxidant and conditioning properties at the ingredient level. Documentation, traceability, and stability data are essential for this application.
