What is MSM supplement?
MSM (Methylsulfonylmethane) is a naturally occurring organosulfur compound found in plants, animals, and small amounts in foods such as fruits, vegetables, and grains; it is widely used as a dietary supplement for joint and connective tissue health. With CAS No. 67-71-0, molecular formula C₂H₆O₂S, and molecular weight 94.13 g/mol, MSM appears as a white crystalline powder with excellent water solubility and high bioavailability. Available in 99% purity, it is commonly packed in 25kg/drum for bulk supply. As a leading bulk MSM supplier, Jayoo Biotech also provides OEM capsules, tablets, soft chews, and customized pet supplement formulations.

MSM Applications
MSM (methylsulfonylmethane) powder is a key functional ingredient widely used in pet supplement formulations, valued for its powerful joint support, anti-inflammatory, and skin health properties. As a bioavailable source of organic sulfur, MSM plays a critical role in maintaining healthy connective tissue, cartilage, and collagen synthesis, making it an essential component in supplements designed for aging or active dogs and cats. Its natural anti-inflammatory effects help reduce joint pain, stiffness, and swelling, significantly improving mobility and daily comfort in pets suffering from arthritis or joint-related conditions. Beyond joint health, MSM supports skin integrity, coat quality, and coat shine by promoting keratin production and reducing oxidative stress. It is also recognized for its ability to enhance immune function and support faster post-exercise recovery in active pets. Commonly blended with complementary ingredients such as glucosamine, chondroitin, and omega fatty acids, MSM powder integrates seamlessly into a wide range of product formats including chewable tablets, soft chews, and powdered supplements. Its proven efficacy, excellent safety profile, and high consumer demand make MSM a go-to ingredient for pet supplement manufacturers looking to develop premium, science-backed wellness products for dogs and cats.
