My show mare, Smart Lena Playboy (barn name Jackie Lovey), injured herself when she was 18 months old which resulted in minor arthritis in her shoulders. When I started to supplement her grain with Horseshine, within a week, I began to notice her movement was more fluid and her performance showed marked improvement. I started feeding the Horseshine Antioxidant last summer and have seen a noticeable improvement in each of my horses, right down to their extraordinarily healthy hooves! I am very impressed with your product and feel fortunate to have found something that addresses so many different issues in very appetizing feedstuff.
