Product introduction
EGCG is a kind of component extracted from Chinese green tea. It is the primary active and water-soluble component of green tea, which has the highest content among the tea catechins. By virtue of its peculiar stereochemical structure, EGCG possesses much stronger anti-oxidant activities and plays an important role in preventing cancer and cardiovascular diseases. In addition, it is potent as the reversal agent of MDR (Multidrug Resistance). As such, it may improve the sensitivity of cancer cells to chemotherapy drugs and reduce toxicity on the heart.

Active Ingredients
- EGCG (Epigallocatechin Gallate): The primary active component, with a guaranteed concentration of 98% (min. 98.0%, max. 99.2%). This is the most potent catechin in green tea, a natural polyphenol with a unique molecular structure that enables it to penetrate cell membranes and exert multi-targeted health effects.
- Minor Synergistic Catechins: Trace amounts (≤2%) of naturally occurring co-catechins, including EGC (Epigallocatechin), EC (Epicatechin), and ECG (Epicatechin Gallate).
- Natural Tea-Derived Co-Factors: Small quantities of L-theanine, chlorogenic acid, and trace minerals (e.g., manganese, selenium) that complement EGCG's activity. L-theanine, in particular, works with EGCG to support cognitive function and reduce stress, while chlorogenic acid enhances antioxidant protection-all naturally present in the raw tea leaves and preserved during our gentle extraction process.
