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 100 mg of calming L-Theanine in a convenient supplement.
