    After switching from MVP to this product, we have found that not only a cost savings, but my competition horses travel better and have less GI upset.

    My Cushing gelding had been having gut problems for over a year. Then a friend of mine found this and said I needed this. She also bought it for her herd too.. Also his mood did a total 360, so happy we found this product!!!

    I have been using this product for over a year at this point on my hot thoroughbred. She has zero issues eating it and her coat, attitude towards work, and comfort has never been better

    I started my 12 yr old gelding on this 1 month ago. He was having a hard time maintaining his weight and nervous. I started seeing results in his attitude within 2 days and his weight is increasing. My boy is so much more relaxed now and his weight is much better. Thank you Blue Bonnet!

    Happy horse

    One of our seasoned competitors started acting out with signs of ulcer discomfort and I had discussed with his owner about doing a round of Ulcer Guard. Our Bluebonnet/Stride advisor happened to be at the barn and asked if we would consider trying the Gastro Phix first to see if it helped. 2 weeks later, the gelding is back to his happy workman like self. We will be turning to this as a first course from now on!
