Green tea extract capsule projects need assay, particle size, COA and sample checks before bulk approval.
Green Tea Extract Capsules Ingredient Specification Overview
This guide is for B2B teams sourcing green tea extract for capsule-format products. It does not discuss consumer serving directions. Instead, it focuses on ingredient specification, powder handling, COA review, sample testing and RFQ preparation. Use the Green Tea Extract product page as the main sourcing page.
Capsule projects usually need a tighter review of powder behavior than a general ingredient inquiry. Filling flow, particle size, color, odor, assay marker and document package should be checked before the buyer compares supplier quotations.
Capsule Specification Checklist
| Checkpoint | What to confirm | Why it matters |
|---|---|---|
| Marker target | Tea polyphenols, catechins, EGCG, caffeine range or buyer-defined marker. | Defines the right green tea extract grade. |
| Particle size | Ask whether particle size data or practical powder handling notes are available. | Supports filling and blending review. |
| Flowability | Test sample behavior with the buyer’s excipients and filling process. | Reduces mismatch between lab sample and production trial. |
| Appearance and odor | Record color, odor and visible consistency from the sample. | Supports incoming material comparison. |
| COA fields | Review assay, microbiology, heavy metals, moisture and other buyer-required fields. | Keeps QA review aligned with specification. |
| Packing and MOQ | Confirm inner bag, drum or carton format, sample quantity, MOQ and lead time. | Connects technical approval with purchasing planning. |
Green Tea Extract Capsules vs Beverage Formulation
| Dimension | Capsule-format project | Beverage project |
|---|---|---|
| Main concern | Powder flow, particle size, assay marker and document match. | Color, taste direction, solubility, clarity and processing fit. |
| Best page | Green Tea Extract product page. | Green Tea Extract supplier guide or liquid formulation guide. |
| Sample test | Blend and filling review in the intended capsule matrix. | Formula trial in the actual beverage base. |
| Document focus | COA, specification, particle notes, packing and sample traceability. | COA, concentration or solubility notes, pH fit and sensory feedback. |
How to Compare Green Tea Extract and EGCG 98%
Not every capsule project needs high-purity EGCG. If the brief names EGCG 98%, the EGCG 98% product page should be the starting point. If the brief asks for a broader tea extract marker profile, the Green Tea Extract product page is usually a better first page for grade selection.
- Use Green Tea Extract when the project brief allows catechin, tea polyphenol or caffeine-target options.
- Use EGCG 98% when the RFQ specifically names high-purity EGCG.
- Ask for representative COA and specification before sample approval.
- Keep sample label, COA, quotation and internal test notes together.
RFQ Checklist for Capsule Projects
- Target ingredient name and marker expectation.
- Capsule format, blend matrix and particle size preference.
- Required documents: specification, COA, packing information and questionnaire.
- Sample quantity, internal test plan and timing.
- Destination market, packaging preference, MOQ expectation and annual volume estimate.

Use the Product Page for RFQ and This Guide for Capsule-Specific Checks
Start with the Green Tea Extract product page for sourcing and compare EGCG 98% only when the project specifically requires high-purity EGCG.
FAQ: Green Tea Extract Capsules Ingredient Specification
Check assay marker, caffeine direction, particle size, flowability, COA fields, sample behavior, packing format, MOQ and document package before approving a bulk order.
No. Some projects need a broader green tea extract marker profile, while high-purity EGCG projects should start from the EGCG 98% product page.
Buyers can request a representative sample and document package after the supplier confirms the target specification, sample quantity, destination market and volume estimate.
Sometimes, but capsule and beverage projects usually have different requirements for particle size, color, taste direction, dispersion and document review.
