Only guaranteed 99.9% pure MSM like that found in Health Direct’s Lignisul MSM is going to provide the quality and assurance of high standards necessary for optimal benefits. Lignisul on the label guarantees quality. Lignisul MSM is made in the U.S. and is an all-natural form of MSM manufactured to the highest quality standards and third party tested to ensure a 99.9% purity level. Cheaper, imported MSM from China is not manufactured to the same quality standards, nor is it third party tested for purity.

MSM and its related compounds are the source of 85 percent of the sulfur found in all living organisms. Many researchers believe that sulfur, the eighth most abundant element in the body, is a sorely neglected mineral nutrient and plays an indispensable role in human nutrition. The cycle of MSM begins in the ocean where microscopic plants called plankton release sulfur compounds. These salts are transformed in the ocean water into the very volatile compound dimethyl sulfide (DMS) which escapes from the ocean as a gas. DMS rises into the upper atmosphere, and in the presence of ozone and high-energy ultraviolet light, is converted into MSM. Lignisul MSM is derived from an allnatural source of DMS that originates in pine trees. MSM is produced by twice oxidizing DMS to form DMSO2 , otherwise known as MSM. Unlike the DMS, MSM is very soluble in water, and returns to earth in the form of rain. On earth, plants take MSM into their root systems and concentrate it. MSM and the sulfur it contains is incorporated into the plants' structure. Through the plants' metabolism, MSM, along with other sulfur compounds it has spawned, is ultimately mineralized and transported back to the sea.
