L-Theanine
L-Theanine is a naturally occurring, non-protein amino acid found in tea that easily crosses the blood-brain barrier and can support the activation of alpha waves. L-Theanine increases levels of neurotransmitters like gamma-aminobutyric acid (GABA) and serotonin that regulate mood and relaxation. By modulating these neurotransmitters, it reduces neuronal excitability, promoting a calm and focused state. It also stimulates alpha brainwaves associated with a relaxed and focused mentality.
