About

EGCG (epigallocatechin gallate) crosses the blood-brain barrier, inhibits beta-amyloid aggregation, and provides antioxidant neuroprotection. Epidemiological data strongly associates regular green tea consumption with reduced cognitive decline risk.

How It Works

EGCG crosses the blood-brain barrier; inhibits beta-amyloid aggregation and tau phosphorylation; modulates dopaminergic and serotonergic pathways; enhances alpha brainwave activity.
