Hello, wanted to let folks know of this wonderful product. I have an older mare that has real issues with confidence and separation anxiety, due to a very troubled time in her life before she came to me. I felt I had to do something and upon investigation into this supplement, I decided to take a chance. What an amazing difference in this mare!!! She is more confident, and comfortable in many regards, she will lead the herd up into the woods for their breakfast as well as be brave and independent going by herself to hay stations. It makes me so happy to see this old gal enjoying her home with me. Highly recommend this product " Formula Exstress Calming" Thank you Glenbrook Farm.
