Research Summary
Clinical research on MSM shows mixed results, with some studies demonstrating modest improvements in osteoarthritis symptoms and joint pain, whilst others show minimal benefit over placebo. A 2018 systematic review concluded that evidence remains inconclusive due to methodological limitations in available studies. More rigorous, large-scale trials are needed to establish definitive efficacy and optimal dosing protocols.
