MSM (Methylsulfonylmethane)
Also known as: Methylsulfonylmethane, Dimethyl sulfone, DMSO2, Organic sulfur
Effective Dosage
1500-3000 mg daily (general use range; limited clinical confirmation)
What the Science Says
MSM is a naturally occurring sulfur compound found in small amounts in foods like garlic, onions, and cruciferous vegetables. It is widely marketed for joint comfort, inflammation reduction, and more recently skin health, based on the idea that sulfur supports connective tissue and collagen structure. Some preliminary studies suggest modest benefits for joint discomfort and possibly skin appearance, but the overall body of clinical evidence is thin — most findings come from small trials, and results are inconsistent.
What It Doesn't Do
Not proven to rebuild cartilage or reverse arthritis. No strong evidence it detoxifies the body. Skin anti-aging claims are largely unproven in rigorous trials. Won't replace proven treatments for chronic joint disease. 'Organic sulfur' branding doesn't make it more effective than standard MSM.
Evidence-Based Benefits
The provided research papers do not contain any studies on methylsulfonylmethane (MSM) as a dietary supplement. The acronym 'MSM' in all provided papers refers exclusively to 'men who have sex with men,' a public health population category. No evidence-based claims about the supplement ingredient can be drawn from these papers.
Weak EvidenceEffective at: No established dose from provided studies

Absorption & Bioavailability
Good — MSM is water-soluble and appears to be well absorbed orally, with sulfur detectable in blood and tissues after supplementation. However, how much reaches target tissues like joints is not well characterized in the provided data.
Red Flags to Watch For
- Only one paper was indexed in the provided data, with no abstract available — the evidence base for this ingredient is very thin
- Widely marketed with broad claims (joints, skin, detox, immunity) that far outpace the available clinical evidence
- Many products combine MSM with glucosamine or chondroitin, making it impossible to isolate MSM's actual contribution
- Doses vary wildly across products (500 mg to 6000 mg+) with no established optimal dose from clinical trials
- Some products use 'OptiMSM' branding as a premium upsell — purity may differ but clinical superiority is unproven
