L-theanine

L-theanine is an amino acid mainly found in tea leaves, especially green tea. It’s known for promoting relaxation without causing drowsiness. L-theanine can help reduce stress and improve focus by increasing the production of calming brain chemicals like GABA and serotonin. Many people use it to enhance mental clarity and reduce anxiety, often feeling more relaxed and alert simultaneously. It generally has a good safety profile and is considered a natural supplement to support mood and mental well-being.
