L-theanin je přirozeně se vyskytující aminokyselina, kterou lze nalézt v rostlině čajovníku zeleného (Camelia sinensis). L-theanin působí jako neuroprotektor, který dokáže procházet hematoencefalickou bariérou a přímo ovlivňovat mozek. Je nejznámější pro své relaxační a uklidňující účinky, zejména ve vysoce stresových situacích. Například čtyři studie s dávkou 400 mg L-theaninu zjistily, že významně snižuje stres a úzkost u zdravých účastníků. 250–400 mg L-theaninu také zlepšilo soustředění, spánek a krevní tlak u zdravých mladých dospělých. L-theanin je uznáván jako bezpečný doplněk s minimem nebo žádnými vedlejšími účinky. Může interagovat s léky na kontrolu krevního tlaku a léčbu rakoviny a není vhodný pro těhotné a kojící ženy. Obvyklá denní dávka L-theaninu je 200–400 mg, přičemž jedna tableta obvykle obsahuje 200 mg.
Užívejte s vodou večer nebo před spaním.
Lze užívat i během dne pro klidné soustředění.
