MSM (Methylsulphonylmethane) is a natural form of sulfur found in all living organisms.  This natural compound, researched since 1979, provides the chemical links needed to form and maintain numerous different types of tissues found in the human body, including connective tissue such as articular cartilage.* While MSM is a natural component of almost all fresh fruits, vegetables, seafood and meat, food-processing methods reduce sulfur levels, making supplementation more important than ever.   NOW® MSM is tested to meet a minimum 99.7% purity level.

What is MSM?

Methyl-sulfonyl-methane (MSM) is a naturally occurring sulfur compound found in our bodies as well as in many common beverages and foods, including milk, coffee, tea and green vegetables. In its purified chemical form, it is an odorless, essentially tasteless, white, water-soluble crystalline solid. It is one of the safest biological substances in biology..

MSM contains 34% elemental sulfur, by weight.

MSM is a non-animal-based nutritional supplement.

Naturally occurring sulfur, such as that found in MSM, is not similar to inorganic sulfides, sulfites and sulfates to which many people are allergic. Also, people who are allergic to sulfur drugs will not normally react to MSM or dietary sulfur.

Where does NOW® Foods MSM powder come from?

MSM is derived from an all-natural source of dimethyl sulfide (DMS) that originates in pine trees. MSM is produced by twice oxidizing DMS to form DMSO2, also known as MSM. Unlike DMS, MSM is very soluble in water. On earth, plants take MSM into their root systems and incorporate it into the plants' structure.

I have been using NOW products for some time and actually was using MSM because of LINGUISIL being used in it. MY last purchase did not use this term. Has the ingredient changed?

Lignisul™ MSM is no longer available, as the company that owned that trademark was dissolved and the trademark is no longer available for this use. We have removed the name from all of our newer labels. Please note that our strict MSM specifications have not changed. The MSM we are using now is of equally high quality and comes from the same producer that made Lignisul™.
