Mental Calmness 100% L-Theanine by Natural Factors, 125 mg 60 Vegetarian Capsules

There’s a reason why drinking a cup of tea is so relaxing. True tea (made from the Camella sinensis plant) contains L-theanine, an amino acid that promotes mental calmness. (In fact, the tea plant was formerly called Thea sinensis!).

A purified form of L-theanine supported by more than 50 studies demonstrating its safety and efficacy. It safely relaxes but won’t cause drowsiness.
