    Happy horse

    Posted by Catherine Hoysa on Jan 5th 2023

    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!

    Great for hard hauling

    Posted by Kirstin Carlson on Oct 5th 2021

    I took off this summer and hauled some horses to get some rodeo seasoning. 5,600 miles in 4 weeks and over a dozen rodeos. I used the performance dose of Gastro pHix on both horses. Both horses, including the super hot Dash Ta Fame 5yo, kept great appetites and never went off feed. They looked great and I even had to let the 5yo back cinch out during the trip. I feel confident that Gastro pHix helped my horses with the stress of hauling and prevented them from getting ulcers that is so common when seasoning young horses.
