Theanine 90caps - Thorne

Thorne's Theanine contains L-Theanine, a compound found almost exclusively in the tea plant (Camellia sinensis), which functions to increase brain neurotransmitters involved in stress control. L-Theanine is an amino acid that has been used safely for decades in Japan. It has been shown that L-Theanine positively modifies brain waves and the key neurotransmitters involved in mood, focus, and memory. L-Theanine increases the production of the neurotransmitters dopamine and serotonin, and also appears to play a role in the formation of GABA – a neurotransmitter that acts as a "brake" during periods of uncontrolled stress. L-Theanine also increases alpha brain wave activity, a marker of relaxation. This effect has been observed to be more pronounced in individuals who subjectively experience the highest levels of stress. A Japanese study of university students found that taking 200 mg of L-Theanine increases alpha brain waves and induces a sense of relaxation. In the same study, the administration of L-Theanine also demonstrated improved focus and attention, and better mood without sedation, starting approximately 40 minutes after ingestion.
