What is L-Theanine?
L-Theanine is a non-protein amino acid naturally found in tea leaves, particularly green tea. It is commonly used as an ingredient in dietary supplements, especially those marketed for stress management, mood support, and sleep enhancement. L-Theanine is valued for its unique chemical structure that may influence neurotransmitter activity. It is often combined with other ingredients in formulations aimed at promoting relaxation and mental clarity without causing drowsiness. Its inclusion is popular in products targeting consumers seeking natural approaches to stress and sleep-related concerns.
