L-Theanine is an amino acid, found in tea leaves, that is used to support the relaxation response, sleep quality and memory.

• L-Theanine supports the production of alpha brain waves which are associated with a state of relaxation. Meditation and daydreaming increase alpha brain waves, which are also present during REM sleep

• L Theanine is not sedative but may help with falling asleep due to its relaxation effect. It has been shown to support sleep quality

• L-Theanine supports the production of GABA (a calming brain neurotransmitter)
• As it is not sedative L-Theanine can be taken during the day to support relaxation
• L-Theanine may also have positive effects on memory and learning
