L-Theanine can be used daily or just when you need to relax.

It supports relaxation without causing drowsiness.

It is a naturally occurring amino acid found in green tea and is a derivative of glutamic acid, a major neurotransmitter in the brain.

Known for its calming effects in the brain, it 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.

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.

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.
