MSM for horses and dogs

Organic source of sulphur (methylsulfonylmethane)

Chia de Gracia MSM is an extremely pure (99,9 %) crystalline organic sulphur compound.

MSM adds sulphur to the diet – one of the body's natural building blocks.

Sulphur is found in the body in amino acids and various protein structures, among other things. It is part of connective tissue, collagen-related structures, and keratin (coat, mane, hooves).

MSM for the sport horse

When a horse is highly active, the body is under constant stress and also constantly renewing itself. Muscles, tendons, and connective tissues are built from proteins, and sulphur is a natural part of these structures.

MSM is often used:

• for actively training and competing horses

• for growing young horses

• together with collagen or vitamin C supplements

• when you want to add a separate organic sulphur source to the diet

Sulphur is part of the body's own protein structures and one of the organism's own building blocks. MSM does not replace a balanced basic diet – it complements it.

Also for dogs

MSM is also suitable as part of a balanced diet for dogs, especially active and highly mobile individuals, when you want to add organic sulphur to the diet.

Sulphur is one of the body's building blocks

When a horse or dog is active, the body is under constant stress, building, and renewing itself. Muscles, tendons, and connective tissues are made up of proteins – and sulphur is naturally part of these structures. Sulphur is not something extra; it is part of the active horse's or dog's own body structure.
