L-Theanine 200mg - 90 Capsules

L-Theanine is a non-proteinogenic amino acid first discovered in green tea leaves (Camellia sinensis) in 1949. Each capsule delivers 200mg of high-quality L-Theanine that has been lab-tested and verified for both product purity and identity. L-Theanine has been granted GRAS (generally recognized as safe) status in the United States.

L-Theanine works by promoting relaxation without causing sleep and influencing amino acid levels that affect serotonin and other neurotransmitters in the brain. It helps balance the negative effects some people experience with caffeine and may support faster reaction time, numeric working memory and improved sentence verification accuracy when combined with caffeine. It is also reported to promote alpha wave production in the brain.

This supplement is designed for adults seeking natural support for daily wellness, particularly those looking to maintain calm focus throughout their day. The capsules are non-GMO, gluten-free, and vegan, making them suitable for various dietary preferences. L-Theanine may be synergistic with Green Tea Extract and works well as part of a balanced wellness routine.
