Life Extension’s L-Theanine supplement contains an amino acid derived from tea. L-Theanine has been shown in several studies to support a healthy stress response and promote a calm, relaxed state of mind.
L-Theanine is an amino acid found in tea that produces calming effects by favorably modulating several aspects of brain activity. L-Theanine induces brainwave patterns similar to those associated with meditation and massage.
Laboratory analysis confirms that theanine used in our formulation contains only the pure L-Theanine form of this amino acid.
