-
High antioxidant capacity at the ingredient level
-
Stable botanical profile suitable for formulation
-
Compatible with multiple delivery formats
Applications
-
Dietary supplements (capsules, tablets, powders)
-
Functional foods and beverages
-
Cosmetic and personal care formulations
Dosage / Specification
Typical use levels depend on purity, formulation type, and target market. Final dosage should be determined by formulators and regulatory teams.
Safety
Tea polyphenols have a long history of use in food and nutrition. Concentrated extracts should be used according to applicable regulations and product design requirements.
Supplier / Manufacturer

At the ingredient level, tea polyphenols exhibit strong redox activity due to their polyphenolic structure. This property makes them suitable for formulations positioned around antioxidant function, ingredient stability, and oxidative balance at the formulation level.
No medical or therapeutic mechanisms are claimed.
6. Application-Relevant Benefits (Regulatory-Safe)
-
Commonly used for antioxidant positioning in finished products
-
Supports clean-label and plant-based formulation strategies
-
Suitable for multi-ingredient blends and standardized formulas
All benefits described relate to functional ingredient properties, not disease outcomes.
7. Usage Guidelines & Formulation Recommendations
-
Select purity based on application (beverage vs supplement vs cosmetic)
-
Evaluate solubility and taste impact in liquid systems
-
Confirm regulatory limits and labeling requirements per market
-
Conduct pilot formulation and stability testing before scale-up
8. Traditional & Modern Industrial Applications
