Methylsulfonylmethane (MSM) - Feed Ingredient

Methylsulfonylmethane (MSM) is a naturally occurring sulfur compound commonly used as a joint supplement in equine supplements and feeds. It is a source of sulfur, which is essential for the formation of connective tissues, hooves, skin, and joint cartilage.

MSM is primarily used as an antioxidant to support joint health and reduce inflammation. It helps combat oxidative stress, which can contribute to joint degradation, muscle soreness, and slow recovery in performance horses or aging equines.

The following equine feeds, supplements and products contain Methylsulfonylmethane (MSM) as an ingredient.
