Perfect for study
The combination of theanine with caffeine in this ratio is perfect for use in times of exams or oppositions, because the addition of theanine reduces the feeling of nervousness typical of caffeine and also allows greater concentration if you know how to keep focused on a single task.
La combinación de teanina con cafeína en este ratio es perfecta para usarla en épocas de exámenes u oposiciones, pues al añadirle la teanina reduce la sensación de nerviosismo típica de la cafeína y además permite una mayor concentración si sabes mantener el foco en una sola tarea.

Great caffeine supplement
This is the best caffeine supplement I have ever taken. The combination of caffeine with L-Theanine makes you feel calm and energized. Highly recommended for days with low energy levels.
