L-Theanine is a naturally occurring amino acid found in tea leaves that promotes calm, focused mental states without causing drowsiness. It works by increasing alpha brain wave activity and supporting neurotransmitters like GABA and serotonin—helping you stay relaxed yet alert.

Often used to reduce acute stress, improve focus, and support the transition into restful sleep, L-Theanine is a safe, non-sedating option for managing mental performance and emotional balance throughout the day.
