I use this on 7 Horses for Arthritic Joint discomfort. I believe it works. All these Horses are Senior aged. from 16 thru 20 years old.
My trainer uses this because it was recommended by her vet. Every horse eats this readily.
Corro always has the best prices. I use MSM as an inexpensive joint support for a horse with no serious joint issues.
Use this on about 15 horses as recommended by our vet. Horses eat it up.
Used at my trainer's barn on every horse. Recommended by vet.
