L-Theanine from NOW Foods:

Promotes Relaxation And Healthy Cardiovascular Function Naturally!

NOW L-Theanine is an amino acid naturally found in green tea that promotes relaxation without the drowsiness or negative side effects associated with other calming agents. L-Theanine also supports healthy cardiovascular function through this relaxing effect as well as its antioxidant properties. L-theanine is a non-protein amino acid mainly found naturally in the green tea plant (Camellia sinensis). L-theanine is the predominant amino acid in green tea and makes up 50% of the total free amino acids in the plant. The amino acid constitutes between 1% and 2% of the dry weight of green tea leaves. L-theanine is considered the main component responsible for the taste of green tea, which in Japanese is called umami. L-theanine is marketed in Japan as a nutritional supplement for mood modulation.
