L-theanine is a naturally occurring amino acid primarily found in tea leaves, particularly in green tea. It is known for its potential to promote relaxation without causing drowsiness. L-theanine is believed to work by influencing certain neurotransmitters in the brain, such as gamma-aminobutyric acid, or GABA, which helps to reduce anxiety and promote a sense of calm. Additionally, it may improve focus and cognitive function, making it a popular supplement for those seeking mental clarity and stress relief. Some studies also suggest that L-theanine can enhance the immune system and improve sleep quality. Overall, L-theanine is valued for its calming effects and potential health benefits.
