Product Review

The amino acid in SEREDYN, l-theanine, increases the activity of a neurotransmitter called GABA. (A neurotransmitter is a natural compound used by the brain to send messages from one nerve cell to another.) Feelings of worry and anxiety often result from low levels of GABA. By naturally increasing the activity of GABA in the brain, l-theanine promotes a sense of tranquility and relieves anxiety. Furthermore, l-theanine increases the activity of another neurotransmitter, dopamine, which promotes concentration and confidence. Thus, l-theanine may calm without causing drowsiness or sedation. Interestingly, the relaxing and focusing effects of green tea result from its high l-theanine content.
