L-theanine is an amino acid found naturally in tea leaves that promotes relaxation without drowsiness. It works by crossing the blood-brain barrier and influencing neurotransmitters, and its potential benefits include improved focus, stress reduction, and better sleep.
L-theanine stimulates alpha brainwaves, which are linked to a calm and alert state.
It may help lower heart rate and cortisol levels, aiding in stress management. It can help promote a calmer mindset, even in stressful situations.
L-theanine can help you fall asleep more easily and improve sleep quality without causing drowsiness. It helps with the transition to sleep and the depth of sleep when taken at night.
It can improve focus, memory, and learning abilities, particularly when combined with caffeine. Some studies show it can improve accuracy and reduce errors when switching between tasks.
