L-Theanine is found almost exclusively in the tea plant Camellia sinensis. It is one of the reasons for the special taste of green tea. Dried green tea, a richer source than black tea, contains about 1-2% L-theanine.
The amount of it in tea can vary considerably and depends in part on how the leaves are further processed after picking. As a result, green tea generally contains much more of this healthy substance than black tea.
Suntheanine®, Sunphenon® TH30 & AlphaWave®
To be sure that the L-theanine you are buying is 100% pure and unadulterated, just look for the patent names Suntheanine®, AlphaWave® and Sunphenon® TH30. The first two are produced through a natural fermentation process that results in a 100% pure L-isomeric theanine. The latter, Sunphenon® is a highly pure extract from green tea.
These are the purest forms of L-theanine. These high quality L-Theanine supplements are also the varieties with the best experiences.
