It works
I bought Evobrain for my daughter during exam time and it has helped her concentration. I am happy with the purchase.

It is necessary to be constant
Nobody should think that in two days you will notice its effectiveness, you have to be constant. When I was 42 years old I decided to go back to school and I started taking it, it is not miraculous but I did notice how my retentiveness improved.

Evobrain
I'm very satisfied with the boost, and this is exactly what I needed. I can maintain my focus for much longer, and that's exactly what I need for both working out and my job.

I recommend 100%.
I have noticed how my concentration improves and I am more active while studying. The only downside is the taste. The plastic wrap tastes too much.

I think it has some effect
For times of study it is good, it does not make a big difference, but it does help and I like that it does not contain caffeine or sugars.

Normal
It is similar to others I have tried, I noticed it kept me awake studying.

First week of use
When we usually talk about these kinds of supplements, the time frame for their effects is long, I must say, however, this one takes effect right away, at least on me.

Study
I had exam periods and it helped me to have more mental focus and be more centered in my day to day life.

Wonder
After two years of competitive exams and a psychological exhaustion that affected me at all levels, this product saved me. Perhaps those of you who use it as an extra will not notice the difference, but in these cases it is super effective.

Complete
Quite complete supplement for the intended purpose. Nothing to envy to other more notorious brands that, however, do not transmit the same confidence as HSN.
