High-quality theanine supplement

L-Theanine benefits have been known around the world, especially in eastern Asia, for centuries. Although the ancient civilizations may have named L-Theanine differently, they understood and explored the relaxing and calming effects of this compound.¹ Theanine used in our formulation contains only the pure L-Theanine form of this amino acid.

Calming Effects

Theanine is an amino acid found in tea.² L-Theanine produces calming effects by favorably modulating several aspects of brain activity. L-Theanine promotes brainwave patterns similar to those associated with meditation and massage.³ Moreover, L-Theanine modulates the formation of the neurotransmitter gamma amino butyric acid (GABA) which in turn modulates levels of two other neurotransmitters, dopamine and serotonin, that also supports relaxing effects.⁴

Life Extension® L-Theanine contains 200 mg of calming L-Theanine in a convenient supplement.
