Green Tea EGCG Antioxidant
Green tea EGCG is the lead catechin in green tea—linked to antioxidant support in research, best from food cups not megadose extracts.
Green tea EGCG (epigallocatechin gallate) is the main catechin antioxidant in Camellia sinensis leaves—higher in steamed Japanese greens than heavily oxidized black tea. EGCG may support endothelial and metabolic health in population studies, but cups are not a cure and supplements can exceed safe intake.
Brewing cooler water and not over-steeping reduces bitterness without wiping out all polyphenols.
Common questions
-
Do EGCG supplements equal green tea?
No—extracts can concentrate doses beyond typical cups and may interact with medications. Food-first green tea with a clinician for any supplement plan is safer.
