msm
Methylsulfonylmethane (MSM) is an organosulfur compound naturally found in plants and animals that serves as a source of bioavailable sulfur. It functions primarily as an anti-inflammatory agent by modulating inflammatory pathways and oxidative stress, while also supporting collagen synthesis and joint tissue health. MSM is commonly used as a dietary supplement for joint pain, osteoarthritis, skin health, and general inflammation reduction.
