Since ancient times it has been said that drinking green tea helps promote relaxation and an overall feeling of well-being. L-Theanine has been there the whole time.

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® to have significant effects on anxiety and other stress-related mechanisms in the body, as well as the ability to promote relaxation and sleep.*
