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.

Well
It doesn't hold as much as they say but it is perfect for long periods where you have to have high caffeine.
No aguanta tanto como dicen pero es perfecta para largos periodos donde tienes que tener la cafeina alta.
