MSM, or methylsulfonylmethane, is an organic sulfur compound. Sulfur is needed to build and maintain proteins, enzymes and connective tissue, and MSM has been reviewed as a nutraceutical used in canine osteoarthritis management for its role in structural and joint maintenance.

MSM for Dogs

Q: Is MSM safe for dogs?

Yes. MSM is a well-studied dietary supplement ingredient in both human and animal use. Broono includes it in Essential for general structural maintenance and in Move alongside boswellia, turmeric, ginger, glucosamine and chondroitin for joint support.

Q: What does MSM do for a dog's joints?

It supplies sulfur used to maintain connective tissue, and in mobility formulas it supports the broader tissue maintenance involved in comfortable movement, which is why Move includes it alongside boswellia, turmeric, ginger, glucosamine and chondroitin rather than as a joint-only ingredient on its own.

Q: Is MSM the same as glucosamine?

No. They're different compounds studied for related but distinct roles: MSM supplies sulfur for structural proteins and connective tissue, while glucosamine is a building block of cartilage matrix. Move includes both because they act on different parts of joint maintenance rather than duplicating each other.

Q: Does MSM have side effects in dogs?

At supplement amounts, MSM is generally well tolerated. The trial behind its safety profile, a double-blind, placebo-controlled study around exercise-induced oxidative stress, reported no notable adverse effects. As with any new ingredient, introduce it gradually and watch for digestive changes.

MSM for dogs: an organic sulfur source, not a joint ingredient on its own

MSM's job is supplying sulfur, the raw material for structural proteins and connective tissue, which is why it appears in both Essential's general maintenance group and Move's joint-support blend, playing a different role in each.

What sulfur has to do with joints

MSM (methylsulfonylmethane) is a bioavailable source of sulfur, an element proteins, enzymes and connective tissue all depend on. A systematic review of nutraceuticals in canine and feline osteoarthritis management covers MSM's place in structural and joint maintenance, alongside its broader role in cellular integrity.

In Move, MSM isn't positioned as a joint ingredient on its own; it supports the wider maintenance of tissues involved in movement, muscles and connective tissue alongside antioxidant systems, working alongside glucosamine and chondroitin rather than duplicating what they do.

Not the same job as glucosamine or chondroitin

MSM, glucosamine and chondroitin are often assumed to overlap because they all show up in joint formulas, but they act on different parts of the same problem: MSM supplies structural sulfur, glucosamine supplies cartilage-building material, and chondroitin manages hydration and cushioning. Move includes all three because none substitutes for the others.
