HelloPharmacist Scorecard of MSM Methylsulfonylmethane 1000 mg by NOW
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
None of the active ingredients could be matched to our evidence database, so intended use can't be graded.
Why this rating?
- None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Every active ingredient lists its own amount on the label.
Why this rating?
- The label discloses an exact amount for 1 of its 1 active ingredient.
- No proprietary blends here — you can verify the dose of every single component.
None of the active ingredients could be matched to our interaction database.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
None of the active ingredients could be matched to our safety data.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.

Formula
MSM (Methylsulfonylmethane) is a sulfur-bearing compound that is naturally present in very small amounts in fruits, vegetables, grains, animal products, and some algae. Sulfur compounds are found in all body cells and are indispensable for life. MSM, in its role in the body's sulfur cycle, helps to create the chemical links needed to form and maintain numerous different types of structural tissues of the human body, including connective tissues, such as articular cartilage and skin.
