A supplement I will definitely be keepingmy 17hh ex-racer Hobbit. He hasn't so much struggled with weight though if he does lose any, he loses it all at once. We have always struggled with condition, especially his back as he has high withers and a high sitting spine.
Since being on comfort gut the improvements are amazing! His back is a lot more even (though it is still a bit spiney) and when tacking him up he no longer kicks out or gets upset. He is a lot more calm when being ridden too. I love comfort gut and its safe to say its a supplement that I will definitely be keeping
