Methylsulfonylmethane (MSM)

The short answer

Small short trials examine osteoarthritis pain; a durable clinically important benefit is uncertain.

Evidence and scope: Mixed evidence
This status does not grade the ingredient for every goal, outcome, or person.
Important limitation: Trials are inconsistent or small, so a reliable clinically important benefit is not established.
Before deciding: Key concern: Anticoagulants, diabetes medicines, pregnancy, and surgery require review.

01 / PRACTICAL GUIDE

Dose, absorption, and combinations

These are indication-specific reference or studied ranges—not a personalized prescription. Start with the objective, then check the form, label, medicines, and health conditions.

Reference range by objective

Joint symptoms1.5–3 g/day in divided doses in many trials

Reference or studied range—not a personalized prescription. The product label or a clinician may specify a different dose.

Dose source ↗

More is not automatically better. A clinician or product label may specify a different amount.

Absorption / solubilityWater-soluble

Water-soluble or readily water-dispersible. This does not mean excess is always harmless.

How it is commonly taken

Take with food if it causes nausea.

Do not combine casually

Anticoagulants, diabetes medicines, pregnancy, and surgery require review.

Dose and use source ↗

Dose and use links lead to primary or official source material. Search links are discovery tools, not proof that every returned paper applies.

02 / EVIDENCE

What the research says

We keep supportive, mixed, negative, safety, and contextual findings together. The headline never replaces the underlying papers.

Does not support the tested claimPMID 19474240

Meta-analysis of dimethyl sulfoxide and methylsulfonylmethane for knee osteoarthritis

The pooled pain reduction was neither statistically nor clinically significant. Only one eligible trial directly tested MSM, so efficacy and long-term safety remain unestablished and the combined participant total is not assigned to MSM.

Published: 20111 primary studies represented

Study design and methods

Design: Systematic review and meta-analysis including 1 MSM and 2 DMSO randomized trials
Population: Adults with knee osteoarthritis; the combined 326-person total could not be isolated to MSM
Intervention: MSM or related DMSO versus comparator
Outcome: Osteoarthritis pain

Complete for the displayed PubMed query at the search timestamp—not for all databases or every possible synonym. Candidates can be irrelevant, duplicate the same study, or report negative findings. They are never summed as evidence or participants until screened.
