L-Theanine is an amino acid found most commonly in tea leaves and in small amounts in Bay Bolegte mushrooms. It can be founding both green and black tea. It’s also available in pill or tablet form. Research indicates that L-theanine promotes relaxation without drowsiness.

A calming effect is usually noted within 30 to 40 minutes after L-theanine is taken at a dose of 50 to 200mg, and typically lasts 8 to 10 hours. Moderate anxiety symptoms often improve with a regime of 200mg once or twice daily.

L-theanine crosses the blood-brain barrier, and has the ability to modulate inhibitory neurotransmitters, selective serotonin, and dopamine to bring about anxiolytic and calming effects.
