L-Theanine’s Mechanism of Action 

L-theanine supports alpha brain wave activity, promoting a calm yet attentive mental state. By influencing neurotransmitters like glutamate, GABA, and serotonin, L-theanine helps maintain focus and clarity while managing stress. It also interacts with NMDA receptors to support calm focus without overstimulation.*
