Methylsulfonylmethane
Organic sulfur donor for connective tissue repair — reduces joint inflammation and supports post-exercise recovery and flexibility.
MSM is an organic sulfur compound found naturally in some foods and the human body. Sulfur is essential for connective tissue, and MSM is commonly used for joint pain, inflammation, and exercise recovery. Often combined with glucosamine and chondroitin for comprehensive joint support.
