L-Theanine is a non-protein amino acid found naturally in the green tea plant (Camellia sinensis). It is an effective GABA precursor and supports healthy relaxation without drowsiness. Because it can cross the blood-brain barrier, L-theanine helps increase brain dopamine levels and helps support a normal immune system. *
