What is it? Theanine is the major amino acid found in green tea. Green tea contains 1 to 3% theanine. Suntheanine is produced via a patented amino acid fermentation process, which mimics the natural process in green tea. The vast majority of the human and animal research has been done using Suntheanine. Some sources may be chemically synthesized.
How does it work in the body? Historically theanine has been used for its relaxing effect. Clinical research suggests that taking 50mg to 200 mg Suntheanine naturally stimulates activity in the brain known as alpha waves, which may result in a relaxed but alert mental state. Perhaps it is like meditation in a bottle. Research suggests that taking theanine 200 mg might induce subjective feelings of tranquility in healthy people. It may promote a healthy response to stress and reduce nervous tension. It has been clinically proven to improve the quality of sleep but won’t cause drowsiness. Other human clinical research suggests that Suntheanine may, diminish normal symptoms of premenstrual syndrome (PMS), improve learning, heighten mental acuity, promote mental clarity and focus, reduce negative side effects of caffeine and support the immune system.
How do you take it? It can be taken with or without meals. You may feel the relaxing effect within 15 minutes but everyone is unique and different.
