Since ancient times it has been said that drinking green tea helps promote relaxation and an overall feeling of well-being. A pioneer in the science of green tea, Taiyo found this relaxation effect to be due to the presence of the amino acid L-theanine. Suntheanine® is the trade name for Taiyo’s patented, pure form of L-theanine. Suntheanine® has been used in more clinical studies than any other L-theanine. Studies show Suntheanine® has significant effects on anxiety and other stress-related mechanisms in the body, as well as the ability to promote relaxation and sleep.


  • Each serving provides 100mg of Suntheanine®, the world’s leading brand of L-theanine.
  • Most well studied and scientifically documented L-theanine in the industry.
  • Suntheanine® has been the subject of numerous scientific studies, all of which demonstrate significant benefits.
  • Manufactured by Taiyo International, world leaders in the research and manufacturing of L-theanine.


  • Suntheanine® helps reduce the acute psychological and physiological responses elicited by specific types of mental stress.
  • Suntheanine® helps support significant brain alpha-wave activity. This increase supports a role for Suntheanine in achieving a relaxed, but alert mental state through a direct influence on the central nervous system.
  • Suntheanine® has been shown to help support healthy blood pressure, possibly by promoting brain alpha-wave activity (reflective of a relaxed state), as well as helping to counteract the stimulatory effects of caffeine.
  • Suntheanine® has been shown to help provide support for PMS-related health issues.
