Overview
L-Theanine is a unique, non-protein amino acid found almost exclusively in the leaves of the Camellia sinensis plant, which is used to make green and black tea. It is famous for promoting relaxation without causing drowsiness or sedation. When paired with caffeine, it creates a synergistic effect that enhances cognitive focus while eliminating the jittery side effects commonly associated with stimulants.
