What the brand says

L-Theanine is a naturally occurring amino acid found in green tea and is a derivative of glutamic acid, a major neurotransmitter in the brain. L-Theanine is known for its calming effects in the brain and has been shown to support concentration and focus while it reduces irritability and low mood states. It directly stimulates production of alpha brain waves, giving the body a sense of deep relaxation and mental alertness without drowsiness. L-Theanine enables the body to produce other calming amino acids, such as dopamine, GABA and Tryptophan and helps with concentration, focus, deep muscle relaxation and improved quality sleep. L-Theanine has been shown to also help the regulation of blood pressure within normal ranges. L-Theanine produces beneficial effects on the nervous and cardiovascular systems.
