MSM (Methylsulfonylmethane)
MSM, or methylsulfonylmethane, is a naturally occurring sulfur-containing compound found in small amounts in plants, animals and the human body. It is commonly used in supplements for joint health, connective tissue support and exercise recovery.
Sulfur is an important component of proteins and connective tissues, including collagen and keratin, which helps explain MSM’s widespread use in formulas for joints, skin, hair and nails.
Joint and Connective Tissue Support
MSM is best known for supporting joint comfort, mobility and connective tissue health.
Its sulfur content contributes to the structure of compounds used throughout cartilage, tendons, ligaments and other connective tissues. MSM is often combined with glucosamine, chondroitin, collagen or hyaluronic acid in joint-support formulas.
Inflammatory and Recovery Support
MSM has been studied for its effects on inflammatory signalling and oxidative stress, making it useful in formulas aimed at physical recovery and healthy movement.
For active people, it may complement regular exercise, adequate protein and other nutrients involved in tissue repair.
Skin, Hair and Nails
Sulfur is also present in keratin and collagen, two structural proteins important for skin, hair and nails.
This gives MSM a natural place in beauty and healthy-ageing formulas, particularly when paired with collagen, vitamin C, biotin or zinc.
MSM for Pets
MSM is widely used in supplements for dogs, cats and horses, especially in formulas for joint mobility, connective tissue, recovery and healthy ageing.
It is often paired with glucosamine, chondroitin, Greenshell™ Mussel and hyaluronic acid to provide broader support for comfortable movement and cartilage health.
