Epigallocatechin Gallate (EGCG)

The most abundant and potent catechin in tea, EGCG accounts for 50-80% of total catechins in green tea. It is a powerful antioxidant with approximately 25-100 times the potency of vitamins C and E. EGCG is most concentrated in shade-grown green teas and rapidly degrades during oxidation, making green and white teas the richest sources. Heat, pH, and storage conditions significantly affect EGCG stability.

Potent antioxidant activity, supports cardiovascular health by improving endothelial function, may aid weight management through thermogenesis enhancement, supports healthy cell growth, neuroprotective properties under active research.
