Quality: it works great for me, I don't like the taste because it is neutral. Effectiveness: I mix it with melatonin and before in the middle of the night I would wake up and start thinking without knowing and now I do wake up and immediately go back to sleep and when you get up is when you notice that you have rested. Presentation: a lot of packaging for such a small amount of product, better in a small bottle.

The taste is quite peculiar, and not pleasant, but it is quite economical.
