Methylsulfonylmethane, a substance from the group of sulfones, the anorangic sulfur compounds, is abbreviated as MSM and serves to supply the joints with nutrients. According to studies, MSM can have an anti-inflammatory effect. The sulfur it contains is also present in cartilage structure and can be useful for cartilage rebuilding, alleviating discomfort and detoxification. The substance is found in both animal and plant products and has no side effects. Combining it with glucosamine is considered particularly effective, and vitamin C may promote better absorption. MSM as an important source of sulfur is used for improved, symptom-free mobility - also in athletes - and generally to support the musculoskeletal system and brain function.
