Methylsulphonylmethane (MSM) is a natural form of organic sulfur found in all living organisms. This natural compound provides the chemical links needed to form and maintain various tissues such as connective tissues and articular cartilages found in the body as well as hair. Bestvite MSM is produced in the United States with a Quadruple Distillation process for unsurpassed quality. Many overseas manufacturers use a method of crystallization to make their MSM, which is generally regarded as a sub-par process compared to distillation.*
