L-theanine 250mg
Highly recommended
Since I started taking theanine at night, I’ve noticed my focus drifts and my mind switches off, making it easier to fall asleep.
Desde que empecé a implementar la teanina por la noche, noto que mi capacidad de concentración se dispersa y mi cerebro deja de funcionar para conciliar mejor el sueño
