Improved alertness
Improves alertness and concentration. Theanine dampens the stimulating effect of caffeine and you don't feel jittery.
Mejora el estado de alerta y concentración. La teanina amortigua el efecto estimulante de la cafeína y no te notas nervioso.

Do not notice much
I didn't notice a big difference, but it goes down easy and does its job for a boost, although I didn't notice too much.
No noté una gran diferencia, pero se toma fácil y cumple su función para un empujón, aunque yo no note demasiado.

Perfect for study
Smart caffeine has been a great ally for my study sessions. It helps me concentrate longer without feeling tired or distracted. Unlike coffee, it doesn't make me jittery or give me energy dips. I feel more awake, focused and clear-headed. Ideal for studying for hours and performing at my best.
La Smart cafeína ha sido una gran aliada para mis sesiones de estudio. Me ayuda a concentrarme por más tiempo sin sentirme cansado o distraído. A diferencia del café, no me pone nervioso ni me da bajones de energía. Me siento más despierto, enfocado y con la mente clara. Ideal para estudiar durante horas y rendir al máximo.
