Everything You Should Know About MSM for Dogs

Methylsulfonylmethane (MSM) is an organosulfur compound known to benefit joint health. But MSM is also used as a health supplement to treat common ailments for aging dogs. Proven as a safe supplement, MSM can boost your dog’s overall health and immune system.

We’ll explain what MSM is and how it is manufactured, its common benefits, and how owners use MSM for dogs. MSM is a viable antioxidant supplement that can improve your dog’s health and lifespan.


Where Does MSM Come From?

MSM occurs naturally and synthetically. Phytoplankton in the ocean release dimethylsulfide (DMS) gas when they die and decompose. When DMS reacts to oxygen and sunlight, it forms methylsulfonylmethane and other sulfates. The MSM is absorbed into the clouds and dispersed to plants through the rain.

For commercial consumption, MSM is synthetically created from a catalytic reaction of dimethylsulfoxide (DMSO) and hydrogen peroxide. DMSO is created by combining paper mill pulp liquid and sulfur that is distilled and extracted.

While MSM is a popular supplement that is safe to ingest, you should carefully consider how the supplement is manufactured and research the quality and potency before purchasing.

Is MSM Good for Dogs?

MSM for dogs is a great preventative supplement that contributes to your dog’s overall health and longevity. MSM is primarily used for:

MSM reduces the pain, stiffness, and swelling associated with these inflammatory conditions.


MSM activates transcription factors that regulate and balance antioxidant enzymes. It can also bind and inhibit free radicals, which improves overall health and fortifies the immune system.

Free radicals are a contributing factor to chronic inflammation and obesity in dogs and cats. As your pet ages, chronic inflammation can lead to several health conditions. By supplementing your dog’s diet with MSM, you’ll be able to reduce this inflammation caused by free radicals.

Immune Modulation

Because MSM supports the immune system, it can reduce stress and modulate the immune system’s response to oxidative stress and inflammation. For dogs that experience heightened levels of stress, MSM can boost your dog’s ability to regulate and reduce stress. Reducing oxidative stress can help prevent cataracts and blindness.

An MSM Supplement May Benefit Your Dog

Because it is a completely safe supplement, there isn’t a downside to supplementing your dog’s diet with MSM, especially if you have an older dog. As your dog ages, its body will become more susceptible to inflammation, oxidative stress, free radicals, and cartilage degradation.

To combat these common health conditions, you should consider an MSM supplement for your dog. Not only will it reduce inflammation and joint pain, but MSM will boost your dog’s overall health, reduce allergies, and fortify its immune system.

It is also okay, if not even better, to take other supplements in addition to MSM. CBD for dogs is something that has been in the market for a few years now and can help just about all the benefits that MSN helps with.
