L-Theanine
L-Theanine is a naturally occurring, unique amino acid found in green tea leaves. L theanine has been found to reduce stress by promoting relaxation without drowsiness, easing nervousness due to overwork and fatigue, and reducing nervous irritability. Human studies suggest that it may also be useful in supporting concentration and in reducing negative side effects from caffeine. XYMOGEN’s L-Theanine (as Suntheanine®) is protected by several patents based on its positive effects.
