First got this product from my vet when I got the bad news that my 24 year old mare has fibrotic myopathy in her hind muscle groups and bad arthritis in her front legs. We thought she'd have to be put down within a couple weeks. He prescribed this and she has improved to the point of being able to live her life comfortably. Quite remarkable.
This product was recommended by our veterinarian and our horse eats it readily in her food. We just started using it and hope we get good results!
