Chronic L-Theanine Administration for Major Depressive Disorder
Can L-Theanine from Green Tea Help Treat Depression?
An open-label study examines the effects of chronic L-theanine administration in patients with major depressive disorder. L-theanine is a unique amino acid found primarily in green tea leaves that has gained attention for its potential mental health benefits. Unlike caffeine, which can increase anxiety and agitation, L-theanine promotes relaxation without sedation and may help reduce stress and improve mood. This study investigated whether regular L-theanine supplementation could provide therapeutic benefits for patients with major depressive disorder when used as a treatment intervention.
