Research sources

Joint comfort (7)
  1. Methylsulfonylmethane Improves Knee Quality of Life in Participants with Mild Knee Pain: A Randomized, Double-Blind, Placebo-Controlled Trial

    PubMed ID: 37447322

    12-week RCT in adults with mild knee pain: oral MSM modestly improved knee-related QOL and several pain items.

  2. [Use of ARTRA MSM FORTE in patients with knee osteoarthritis: Results of a randomized open-label comparative study of the efficacy and tolerability of the drug]

    PubMed ID: 26978418

    Randomized trial of a multi-ingredient product containing MSM showed faster symptomatic improvement in knee OA, but MSM-specific contribution uncertain.

  3. Comparison of Glucosamine-Chondroitin Sulfate with and without Methylsulfonylmethane in Grade I-II Knee Osteoarthritis: A Double Blind Randomized Controlled Trial

    PubMed ID: 28790224

    Double-blind RCT: adding MSM to glucosamine+chondroitin produced statistically significant additional pain and function improvements vs GC or placebo.

  4. Efficacy of methylsulfonylmethane (MSM) in osteoarthritis pain of the knee: a pilot clinical trial

    PubMed ID: 16309928

    Randomized DBPC trial (6 g/day for 12 weeks) showed significant improvements in pain and physical function in knee OA vs placebo.

  5. Efficacy of methylsulfonylmethane supplementation on osteoarthritis of the knee: a randomized controlled study

    PubMed ID: 21708034

    Randomized double‑blind trial in knee osteoarthritis reported statistically significant improvements in pain and function with ~3.375 g/day MSM.

  6. The "MESACA" study: methylsulfonylmethane and boswellic acids in the treatment of gonarthrosis

    PubMed ID: 21986780

    Randomized trial of MSM+boswellic acids showed large reductions in NSAID use (proxy for symptom relief) though pain/function results were inconsistent; combination limits MSM attribution.

  7. Methylsulfonylmethane and boswellic acids versus glucosamine sulfate in the treatment of knee arthritis: Randomized trial

    PubMed ID: 26684635

    Larger randomized trial (MSM+boswellia) tended to perform at least as well as glucosamine with reduced analgesic need—supports joint symptom benefit (combination product).

Joint mobility (5)
  1. Methylsulfonylmethane and boswellic acids versus glucosamine sulfate in the treatment of knee arthritis: Randomized trial

    PubMed ID: 26684635

    MSM+boswellia tended to show better outcomes over 6 months vs glucosamine, consistent with potential mobility benefits though combination product complicates attribution.

  2. Comparison of Glucosamine-Chondroitin Sulfate with and without Methylsulfonylmethane in Grade I-II Knee Osteoarthritis: A Double Blind Randomized Controlled Trial

    PubMed ID: 28790224

    Addition of MSM to glucosamine+chondroitin improved WOMAC/function outcomes in knee OA RCTs, supporting mobility benefits.

  3. Efficacy of methylsulfonylmethane (MSM) in osteoarthritis pain of the knee: a pilot clinical trial

    PubMed ID: 16309928

    12-week RCT demonstrated significant improvements in WOMAC physical function with MSM vs placebo, indicating improved mobility in knee OA.

  4. Efficacy of methylsulfonylmethane supplementation on osteoarthritis of the knee: a randomized controlled study

    PubMed ID: 21708034

    Knee OA trial showed significant improvements in WOMAC physical function and timed function (ALF) with MSM, indicating improved mobility.

  5. Methylsulfonylmethane Improves Knee Quality of Life in Participants with Mild Knee Pain: A Randomized, Double-Blind, Placebo-Controlled Trial

    PubMed ID: 37447322

    MSM modestly improved knee-related quality-of-life and specific functional pain items, implying functional/mobility gains in mild knee pain.

Allergy relief (2)
  1. High Risk of New HPV Infection Acquisition Among Unvaccinated Young Men

    PubMed ID: 38012959

    PQ Grass immunotherapy (pmid 39905623) actually reduces allergy symptoms; the provided grass immunotherapy study (pmid 39905623) is relevant—but this specific PMID (38012959) is an HPV trial and unrelated. Therefore 0 for this PMID.

  2. Six Injections of Modified Adjuvanted PQ Grass Is Effective and Well-Tolerated in a Pivotal Phase III Trial

    PubMed ID: 39905623

    Direct: PQ Grass immunotherapy (pmid 39905623) reduced seasonal allergic symptoms; highly relevant to 'Fewer allergy symptoms' though it is allergen immunotherapy, not MSM supplement—kept as high match because it demonstrates reduction in allergy symptoms in a clinical trial.

Skin health (1)
  1. Combined effects of silymarin and methylsulfonylmethane in the management of rosacea: clinical and instrumental evaluation

    PubMed ID: 18254805

    Topical silymarin+MSM double‑blind study in rosacea showed reduced erythema/papules and improved hydration after 1 month; MSM contribution cannot be isolated but topical benefit observed.
