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.

For a complete approach to stress relief and relaxation, pair Premier L-Theanine with Tranquinol®, which features Suntheanine®, Affron®, magnesium malate, and synergistic botanicals for more comprehensive CNS support.
