UltraCruz Equine MSM Supplement for Horses is a natural source of non-metallic sulfur that supports both bone and joint health. Horses in training and competition, as well as those requiring additional joint support, may benefit from this supplement. MSM is a source of organic sulfur, which is required for a number of functions in the body. It has been shown that MSM helps aid in the health of collagen and cartilage. For additional joint support, we recommend adding UltraCruz Equine Glucosamine Sulfate Supplement for Horses and UltraCruz Equine Chondroitin Sulfate Supplement for Horses to your horse's supplement routine. All of these supplements may be safely fed together to support equine joint health.Developed and manufactured in the USA with globally-sourced ingredients by Santa Cruz Animal Health

  • Equine joint supplement for connective tissue, bone and joint health
  • Supports collagen, glucosamine, and chondroitin production
  • Helps support the structural integrity of joints and connective tissues
  • Provides MSM as a pure powder form

Aging herd

I have a number of aging therapy horses and I feed MSM to them all. It really helps with their flexibility and joint health. They play hard!!

WHAT A DIFFERENCE!!!

5 months ago
I purchased this product for my 20 year old Shire gelding, and after giving this to him for a few weeks and working through his system. What a difference in his performance during the seasons. He went from sore, cracking and popping leg joints to having lots of energy on the coldest of days. His stamina has seen a real comeback and I'm excited to see what 2026 riding season is going to be.

Horses Willing to Eat It

5 months ago
There’s no odor and the horses eat it; which is great. I don’t know yet if it’s helping my asthmatic horse or not because I haven’t been feeding it long enough and it’s winter so it’s not allergy season. I wanted to get started before Spring. It’s rather difficult to locate the clear plastic scoop against the white powder and I wish it was tan or grey. It’s more granular than powdery so it doesn’t blow around in the wind.
