US market: Green tea extract is commonly used in supplement formulas. Suitable positioning includes antioxidant support, metabolism support, and healthy weight management support. Avoid disease claims and review caffeine disclosure when applicable.

Frequently Asked Questions
40% to 50% EGCG is common for mainstream antioxidant and metabolism formulas. Higher grades such as 90% or 98% are used when brands need a smaller serving size or premium active positioning. Higher EGCG is not always better because daily intake limits and label warnings may apply in some markets.
Yes. Decaffeinated and low-caffeine grades are available for stimulant-free formulas. If your product is positioned as caffeine-free or stimulant-free, request caffeine testing on the COA and confirm your acceptable caffeine threshold.
Check EGCG percentage, total catechins or tea polyphenols, caffeine level, heavy metals, microbiology, pesticide status, and solvent residues. For EU-bound products, daily EGCG content and warning requirements should be reviewed before label approval.
Every sample and bulk order includes COA, MSDS, and product specification sheet. For standardized grades, the COA includes the relevant active marker assay where applicable. Heavy metal data, microbiology results, allergen statement, Non-GMO statement, flow chart, and country of origin declaration are available for bulk orders.
Green tea pairs well with caffeine, L-theanine, berberine, bitter melon, chromium, turmeric, resveratrol, grape seed extract, vitamin C, and B vitamins depending on the formula. For stimulant-free products, use decaffeinated green tea and avoid caffeine-bearing partners.
Price depends on EGCG percentage, catechin profile, caffeine limit, organic status, pesticide screening, and annual volume. High-EGCG and decaffeinated grades usually cost more because they require tighter processing and testing.
Minimum bulk order is 1kg, with formulation samples available from 20g. Bulk lead time is usually 10–15 business days depending on selected specification, inventory, documentation requirements, and destination market.

EGCG note
For export formulas, do not choose a high-EGCG grade only because it looks stronger. Check finished-product daily EGCG exposure and target-market rules first.

Green tea extract buyer questions often mix EGCG powder, tea polyphenols, caffeine limits, and green tea L theanine content questions. For bulk sourcing, those terms should be separated into clear specifications so supplement brands receive the right Green Tea Extract EGCG material instead of a mismatched tea amino acid request.
