Momentous L-Theanine Supplement, Supports Relaxation & Focus, 200mg

What the brand says

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