Botanical Extract
Green Tea
Camellia sinensis
Green tea extract is made from unfermented Camellia sinensis leaves, preserving catechin content that oxidation destroys in black tea processing. EGCG is the most abundant and most-studied catechin; extracts are standardized either to total polyphenols or specifically to EGCG.

Do you provide a Certificate of Analysis?
Yes, COAs are available per batch — this will be provided alongside your order.
