Methylsulfonylmethane

A naturally occurring organosulfur compound and the oxidised metabolite of dimethyl sulfoxide (DMSO). MSM delivers bioavailable sulfur for cysteine, methionine, glutathione, and connective-tissue sulfation pathways.

White to colourless crystalline powder, odourless to very faintly sulfurous, with a slightly bitter taste. Highly water-soluble. Heat-stable through standard tabletting and beverage-processing temperatures, with a melting point near 109 °C.

We supply food-grade Methylsulfonylmethane from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production. We can supply distilled MSM produced by four-stage distillation (as opposed to crystallisation), which is the premium-grade specification preferred by US joint-health brands.

Common market grades include 99.9 percent distilled MSM (the premium grade for joint-health products), 99 percent crystallised MSM (the volume-market standard), and pharmaceutical-grade material meeting USP specifications. Particle-size options include fine powder for capsule fill and coarser granular formats for direct compression.

Bulk and reduced-MOQ shipments. Batch-level COA covering assay, related substances including DMSO and DMSO2 impurities, heavy metals, and microbiology.

MSM is a natural compound present in trace amounts in many fresh foods, including milk, fruit, vegetables, and tea, although content degrades substantially during processing and storage. The molecule was developed as a commercial supplement ingredient in the 1980s after veterinary work on DMSO indicated that the oxidised MSM metabolite delivered comparable benefits with substantially better tolerability and odour profile.

Industrial production proceeds by oxidation of dimethyl sulfide or DMSO with hydrogen peroxide, followed by either crystallisation or four-stage distillation. The two finishing routes deliver chemically equivalent material but differ on residual-solvent profile and trace-impurity content, with distilled grades commanding a price premium in the US premium-supplement channel.

Recognised as Generally Recognized as Safe by the U.S. FDA (Self-Affirmed GRAS, with several GRAS notices accepted by the agency without objection), approved as a food and supplement ingredient by EFSA, and approved as a Health Food monograph ingredient in China. Australia, Japan, and Korea recognise MSM under their respective supplement frameworks.

The principal commercial value proposition is delivery of bioavailable sulfur to support the body's sulfation pathways: cysteine and methionine biosynthesis, glutathione regeneration, and sulfation of glycosaminoglycans in cartilage and connective tissue. Clinical evidence supports use in osteoarthritis at doses from 1.5 to 6 grams per day, typically over 12 weeks.

Sulfur as an element is relatively abundant in the diet through protein-derived amino acids, but the specific MSM molecule and its bioavailability profile have established a commercial position that no whole-food sulfur source has displaced in the joint-health category over four decades.
