What Is MSM (Methylsulfonylmethane)?
MSM (methylsulfonylmethane) is a naturally occurring sulfur compound found in plants, animals, and humans. This organic sulfur plays a vital role in maintaining healthy connective tissues, supporting collagen production, and reducing inflammation* throughout the body. In dogs, MSM helps maintain joint flexibility and comfort while supporting natural healing processes*.
What makes MSM particularly valuable for canine health is its ability to reduce inflammation without pharmaceutical side effects. The compound works at cellular levels to support tissue repair and maintain structural integrity of joints, cartilage, and ligaments. MSM is commonly combined with glucosamine and chondroitin in dog supplements, creating synergistic effects that enhance overall joint health and mobility support for dogs of all ages and activity levels.
