  • Sulphur plays a key role in the production of collagen, which is a component of cartilage and connective tissue, so vital for joint health.
  • Sulphur helps to support the horse's own natural anti-inflammatory and antioxidant processes, and so helps joint comfort and mobility.
  • Sulphur is a component in the production of certain vitamins and amino acids, including vitamin B1, biotin and methionine.
  • Helps promote healthy skin, coat and hooves.

Product Description


MSM is found naturally in many fresh forages, but in very small quantities - usually in insufficient quantities to fully support the horse's own anti-inflammatory and antioxidant processes. It is also lost during the production of preserved forages such as hay and haylage.

MSM is a very bio-available source of the key mineral sulphur. Sulphur is a vital component of key amino acids such as methionine (important in hoof health), and important vitamins such as Vitamin B1 and Biotin.

Sulphur also plays a key role in the production of collagen, which is an important component of cartilage - one of the vital shock absorbing compounds in joints, and in connective tissue (tendons and ligaments).

The bioavailable sulphur from MSM will also promote healthy skin and coat, as well as stronger hoof horn, through its role in the synthesis of important sulphur containing amino acids and vitamins, such as biotin and methionine.

What are the benefits of MSM?

  • Supports the horse's own anti-inflammatory processes to support joint health and comfort.
  • Supports the production of collagen to support healthy cartilage, ligaments and tendons.
  • Helps reduce oxidative stress.
  • Helps promote healthy skin, coat and hoof horn.
