L-THEANINE
L-Theanine is the major amino acid found exclusively in green tea which is responsible for the relief of stress and for wellbeing that we feel after drinking green tea.

SUNTHEANINE®
Suntheanine® is the trade name for Taiyo’s patented 100% pure L-isomeric form of L-theanine (L-glutamic acid-gamma-monoethylamide). Suntheanine® is the award winning, patent protected pure L-theanine from Taiyo. Taiyo exclusively produces Suntheanine® via a patent protected enzymatic method that mimics the natural production of L-Theanine in green tea leaves. Suntheanine® is 100% water soluble and highly bioavailable. It has a unique sweet taste known as “umami” or 5th taste. Suntheanine® can be used in RTD and instant beverages, tablets sachets, effervescent, teas and many other dietary supplement and food applications.

CENTRAL MODE OF ACTION
L-Theanine is a simple amino acid derivative from the amino acid glutamine (Glutamine-ethylamine). As a small amino acid L-Theanine can pass the brain blood barrier and in the human brain and also in other nerve cells it interacts with the glutamate sensitive NMDA receptor. L-Theanine slightly reduces the sensitivity and activity of the NMDA receptor which pumps calcium (=cell excitement) into nerve cells. This is a similar action as magnesium does as counterpart of Calcium leading to muscular rand nerve relaxation. Such a central mode of action elicits many visual and perceptible physiological effects and benefits. For example, L-theanine, increases the appearance of alpha waves in the brain that promotes alertness and relaxation without causing drowsiness.

MANY HEALTH BENEFITS
Suntheanine® administered orally at 200 mg/serving significantly induced alpha wave (alpha 1&2) production within 30-40 min indicating a relaxed yet alert state of mind. ln subjects having anxiety, the relaxation effect was observed even at a dosage of 50 mg/serving. In addition to relaxation, Suntheanine® exhibited the potential to reduce physical stress, symptoms of PMS and a normalization of blood pressure. Suntheanine® also creates alertness, but a totally relaxed state of mind without causing drowsiness. Suntheanine® is clinically proven to reduce stress, helping to fall asleep and improving sleep quality.

Suntheanine® also diminishes symptoms of PMS, ADHD and anxiety and suppresses side effects of caffeine. Various studies have also shown Suntheanine to promote learning ability, concentration, memory, as well as an antagonist to the negative effects of caffeine. Unlike several anti-stress herbs such as Kava Kava (Piper methysticum), Valerian (Valeriana officinalis) and St. John’s Worth (Hypericum perforatum), no caution is required in the use of Suntheanine® as it does not lead to drowsiness nor does it induce sleep. Suntheanine® is also much safer than any herbal extract because it is a natural amino acid metabolite that our body can easily transform into the body own amino acid glutamine and ethylamine.

SAFETY OF SUNTHEANINE®
Suntheanine® is extremely highly purified 100% L-Theanine which is the only natural and active Theanine form in a purity of 98.9%. As a glutamine derivative Suntheanine® is either excreted via the urine or it can be easily metabolized in every human cell into glutamine and ethylamine. Both metabolites are natural components that can be used by the body in several ways. Many clinical tests have confirmed the safety of Suntheanine®, which was recognized as GRAS in United States and recommended for unlimited use in Japan. Suntheanine® received the best food ingredient research award in FIE 1998 and best nutraceutical award in Nutracon 2000. Suntheanine® is sold since more than 20 years in the US as dietary supplements and millions of consumers consumed Suntheanine without any side effects.

Very important fact is that Suntheanine® does NOT have a sedative action and does not increase drowsiness or sleepiness. Suntheanine® increases mental alert, mental concentration and focus without increasing mental fatigue.
