L-Theanine Supreme

With Suntheanine® to help temporarily promote relaxation.



We often hear about our stress response being referred to as fight or flight or rest and digest. Our fight or flight response happens when our nervous system is in a “sympathetic” state, while a rest and digest response means our nervous system is in its “parasympathetic” state. Family issues, work deadlines, the news, traffic, and many of the events we experience each day will keep us in a sympathetic state. Being in this state for long periods of time may lead to increased inflammation, tissue damage and reduced immunity. Parasympathetic mode is much better for our health and longevity! Activities like yoga, deep breathing, meditation, walking in nature, and adequate sleep can help us get there. Since we can’t practice yoga in the forest all day, we may need some extra support.


Since ancient times, it has been documented that tea has been used to help promote relaxation. Studies are showing that it’s the L-theanine, found in high amounts in green tea, that is responsible for this relaxing effect. Suntheanine® L-theanine is not an extract of green tea, but rather is produced via a patented process that mimics the natural process in green tea leaves, resulting in a 100% pure L-isomer-theanine. Suntheanine® is backed by more than 60 human clinical studies documenting its ability to help to temporarily promote relaxation, while improving focus, alertness, attention, concentration, and even sleep. Clinical research suggests that 50 to 200 mg of Suntheanine® stimulates alpha brain waves, which are associated with a relaxed but alert mental state.
