l-Theanine is a unique amino acid originally found in tea. l-Theanine has also been discovered as a biologically active compound responsible for promoting relaxation. It acts by decreasing cortisol levels during stress and regulating neurotransmitters activity in the brain. In a preliminary non-clinical study, an l-Theanine solution enhanced alpha wave production in the occipital and parietal regions of the brains of volunteers. These observed patterns are considered to be an index of relaxation. Furthermore, it did so rapidly and without causing drowsiness. In two additional studies, alpha waves were also shown to be detectable soon after l-Theanine administration. Furthermore, l-Theanine has been reported to moderate the effects of caffeine on the central nervous system. Pure Encapsulations l-Theanine is Suntheanine®, the brand which has been used in scientific studies.
