SMART CAFFEINE *
It hasn't kept me awake at night.
I bought it as a substitute for coffee in the morning and even taking an extra coffee has not kept me awake at midday. I have to say that I have been taking it for 3 months.

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.

Great for study times, I have tried them and without a doubt it is a great supplement, both in the gym and in the studio.

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.

Intelligent caffeine
When combined, caffeine and L-theanine have an effect on concentration without making us nervous. Improving cognitive function.

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.

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.

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

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.
