SMART CAFFEINE
I love it
I am delighted with this long-acting caffeine, as the normal one made me too active. You can feel it throughout the day, and it's ideal for the afternoon and evening shifts.
Encantada con esta cafeína de acción prolongada, ya que la normal me ponía demasiado activa. Ésta la vas notando durante todo el día, me va ideal para el turno de tarde y noche.

It fulfills its function.
I was taking them during a season of high work stress that required me to stay awake for many hours and they do the job. I took them in the morning and it is like drinking several coffees.
Las estuve tomando una temporada de mucho estrés laboral que necesitaba estar despierta muchas horas y cumplen su función. Las tomaba por la mañana y es como tomarte varios cafés.

Effective and well presented.
Good caffeine, effective and good presentation, I do not use it daily only when I need a little activation, since I do not usually drink coffee and I notice its effects.
Buena cafeína, efectiva y buena presentación, no la uso diariamente sólo cuando necesito un poco de activación, ya que no suelo tomar café y noto sus efectos.

SMART CAFFEINE
Basic in my daily life.
Well, for me it is a basic in my daily workouts, as a pre-workout. It helps me improve my concentration and performance. The format is convenient and easy to ingest. I always recommend it. Every day I take it before my strength and cardio workouts half an hour before exercise. And I have stopped drinking coffee for the rest of the day, because I really don't need it anymore. Ideal format.
Pues para mí es un básico en mies entrenamientos diarios, como pre-entreno. Me ayuda a mejorar mi concentración y rendimiento. El formato es cómodo y fácil de ingerir. Lo recomiendo siempre. Cada día lo tomo antes de mis entrenamientos tanto de fuerza como de cardio media hora antes del ejercicio. Y he dejado de tomar café durante el resto del día, porque realmente ya no lo necesito. Formato ideal.

SMART CAFFEINE
6 coffee and 5 tea in one tablet
The effect is more long lasting rather than short lasting. It is useful for concentration and study. It avoids the negative effects of caffeine and theine. I don't recommend it for sleep attacks. Better other products with heavy immediate effect. I never drink tea and coffee. If you drink tea and or coffee regularly consider larger doses
L'effetto è più di lunga durata piuttosto di breve durata. È utile per la concentrazione e lo studio. Evita gli effetti negativi di caffeina e teina. La sconsiglio per i colpi di sonno. Meglio altri prodotti con effetto pesantemente immediato. Io non bevo mai te e caffe. Se bevi te e o caffe regolarmente considera dosi maggiori

Effective.
Previously I bought the natural caffeine, but I noticed the caffeine peak and then I would get the crash again. So I tried this one, which has a prolonged effect and is much better. Of course, each person is different and the effects may vary. I am just telling you my experience.
Anteriormente compré la cafeína natural, pero notaba el pico de la cafeína y luego me daba el bajón otra vez. Así que probé esta que es de efecto prolongado y mucho mejor. Eso sí, cada persona es un mundo y los efectos pueden variar. Sólo cuento mi experiencia.

Super
Great product. Has a good effect. Whether in everyday life or during sport. I am fit and focused, but not as exhilarated as with caffeine tablets. I take it regularly.
Tolles Produkt.
Hat eine gute Wirkung. Egal ob im Alltag oder beim Sport.
Ich bin fit und fokussiert, aber nicht so aufgekratzt wie bei Koffein Tabletten.
Ich nehme es regelmäßig.
