    Glutamate, anxiousness, and stress

    Glutamate is associated with anxiousness and stress

    • Stress activates the hypothalamus-pituitary-adrenal (HPA) axis which releases glucocorticoids that affect brain function
    • Studies have shown that the brains of both pediatric and geriatric populations are particularly susceptible to stress

    L-theanine acts as a glutamate receptor antagonist

    • L-theanine binds to glutamate receptors (AMPA, kainate, and NMDA receptors) and blocks the binding of glutamate to its receptors

    L-theanine improves sleep efficiency

    The effects of L-theanine were assessed in randomized, double-blind, placebo-controlled studies

    • In individuals 8-12 years of age, L-theanine (200 mg) twice daily (morning and afternoon) significantly increased sleep efficiency (percentage of night spent sleeping restfully) and reduced nocturnal motor activity
    • In adults, single administration of L-theanine (200 mg) significantly reduced feelings of stress under mental strain
