L-teanin je aminokiselina koja se obično ne nalazi u prehrani. Nalikuje neurotransmitera GABA i glutamat i funkcionira na sličan način u mozgu kada se guta. L-teanin promiče opuštanje bez sedacije, podržava upravljanje stresom i povećava pažnju. Često se kombinira s kofeinom kako bi se smanjio podrhtavanje uzrokovano kofeinom i poboljšao kognitivne funkcije poput memorije, fokusa, energije i rješavanja problema.
