Green tea is unoxidised Camellia sinensis leaf, preserving its full spectrum of catechin polyphenols — most notably EGCG, one of the most extensively researched plant compounds. It supports cardiovascular health, cognitive function, metabolism, and DNA repair. Its mild caffeine content provides gentle alertness without the jitteriness of coffee, synergising with L-theanine for calm focus.
