I've been using this for my dog in replacement of Prozac. After regular use, I've noticed her mood has been more balanced and she's generally happier. I will be ordering again.

I got these to try to have more restful sleep. I think they are helping. They are a fairly large pill but seem to dissolve quickly plus they are at a better price than other brands.

Pure calm

Every capsule was filled full, there was no damage to any of the capsules, and the product looked very clean and pure. I do not like to take pills because they do not absorb well. This is powder inside a capsule and that makes it absorb very well.

Not so good

I got it to help with calming, unfortunately I have the opposite effect. It has a little caffeine so if you are sensitive this is not for you.
