High L-Theanine Teas...
L-Theanine naturally occurs in all Camellia sinensis, the tea plant. Growing conditions, however, can influence the level of L-Theanine in various teas. In fact, the ONLY place L-Theanine naturally occurs other than in tea is in one type of mushroom, Boletus badius.
The benefits of L-Theanine are wide-ranging but most notable are its ability to lower blood pressure, create a calming effect, work in synergy with the caffeine in tea to create a clear-calm state of mind, help prevent cancer, and allow us to more easily relax our mind when our heads hit the pillow.
L-Theanine can be purchased as a supplement, but why on earth would you take a supplement when you can be enjoying high L-Theanine concentrations and its benefits from delightful cups of tea?
