Interesting for mental clarity
It is an interesting product for greater mental clarity although its effectiveness is moderate but it is convenient to take it into account and combine it with caffeine for a better synergistic effect.

Surprised
It is the first time I take this supplement, and surprised, from the first day you notice the "soothing" effect without losing concentration or activation, do not sedate you let's go....I take one in the morning with matcha tea or coffee (as I give the day) and one at night with melatonia....and hey.... I get up more calm (and that I am one of those who goes twice to the bathroom to drink plenty of water during the day) and I have improved sleep maintenance. Highly recommended.
