L-Theanine for sleep

The sleep Foundation article explores L-theanine, an amino acid found in tea leaves, and its potential benefits for sleep. L-theanine is believed to promote relaxation by influencing neurotransmitters like GABA, serotonin, and dopamine, which can reduce stress and anxiety levels. Additionally, it may enhance alpha brain wave activity, associated with a relaxed yet alert mental state, potentially facilitating the transition into sleep. While some studies suggest that L-theanine can improve sleep quality without causing daytime drowsiness, the article emphasizes the need for more comprehensive research to confirm these effects. For those considering L-theanine supplements, it's recommended to consult with a healthcare provider to ensure safety and appropriateness, especially when dealing with existing health conditions or medications. Maintaining good sleep hygiene practices remains essential for optimal brain health and cognitive performance.
