Common Names: L-Theanine
Scientific Names: (2S)-2-Ammonio-5-(ethylamino)-5-oxopentanoate[2] or N-Ethyl-L-glutamine
Theanine is a natural amino acid found primarily in tea leaves, especially in Camellia sinensis, the plant from which black, green, and white teas are derived. This supplement has gained recognition for its potential cognitive and relaxation-enhancing properties. Theanine is known to promote a sense of calm and reduce stress and anxiety without causing drowsiness. It works by increasing the levels of various neurotransmitters, including GABA (gamma-aminobutyric acid), which plays a key role in regulating relaxation and mood. Theanine also has the potential to enhance cognitive function, focus, and memory. As such, it is often used to complement caffeine in various nootropic or cognitive enhancement supplements, as it can offset the jittery side effects of caffeine while maintaining alertness. Theanine is available in supplement form, typically as capsules or tablets, and it is a popular choice for individuals seeking natural support for both mental relaxation and cognitive performance. However, it's important to consult with a healthcare professional before incorporating Theanine into your routine, especially if you have specific health concerns or are taking other medications, as it may interact with certain drugs or have contraindications in some cases.
