The only thing that has workedMy mare has been on comfort gut for a month now and I have seen a huge improvement in her condition! She was like a rake after being on regumate for the spring and struggled to put back on condition after coming off of it despite using various supplements for the last couple of months. Comfort gut is the only thing that has worked, and it seems to have helped with her stable walking as well. It is definitely something she will be staying on for the foreseeable future!
