My OTTB is slightly anxious and can be a bit jumpy/spooky. I tried this supplement and it was effective almost immediately. It helps to just take the edge off and help him be a little more calm. Obviously it’s not as strong as a prescription drug you might get from the vet, but I liked that. My horse still has a clear mind and improved mood. He loves to eat it, no issues with taste it seems. I love that it comes in proportioned packets, it makes it so easy to make his feed. I mix it in with his regular feed. This supplement is now a permanent fixture in his diet.

Love this product, but I think they changed the formula

I used too love this, and my horse ate it. Currently, I am not sure if they changed the formula - but, I had to change as my horse wouldn't eat it anymore. I loved
