MSM (methylsulfonylmethane) is naturally occurring in the human body and in many foods, primarily raw seafood and, to a lesser degree, in fresh fruits and vegetables. MSM is 34% sulfur – the fourth most abundant mineral in the human body.

MSM is 34% sulfur – the fourth most abundant mineral in the human body. Sulfur is necessary for the maintenance of healthy joints, tendons, ligaments and other connective tissue, and is associated with collagen and the production of keratin.* OJIO offers only OptiMSM®, an ultra-pure, high quality MSM backed by numerous pre-clinical studies for its safety and efficacy. OptiMSM® is produced via a proprietary four stage distillation process which removes heavy metals and contaminants that can be present in MSM produced by a crystallization process.* OptiMSM® BENEFITS:

  • Supports joint function and mobility: protects cartilage
  • Helps combat exercise-induced oxidative stress
  • Aids in reducing muscle soreness: helps support recovery


The World’s most pure MSM
U.S.-made OptiMSM® is a premium form of MSM trademarked and sold into the dietary supplement marketplace. Introduced in 1989, it has been a leading ingredient for joint health products and the choice of quality brand manufacturers. Methylsulfonylmethane (MSM) is created naturally through the earth’s sulfur cycle when phytoplankton and algae die and decompose, releasing sulfur compounds into the atmosphere where they are transformed to DMS. In the presence of ozone and sunlight, DMS is converted to DMSO and MSM. Both are water-soluble and return to the earth’s surface in rain water and are absorbed by vegetation and ultimately eaten by animals. These sources contain very small amounts of MSM, typically < 1 ppm, with the highest concentration in mammal’s milk at 8.2 ppm. Therefore, all commercially available MSM must be manufactured because the amounts found naturally are too small to be extracted.

Dosing Instructions

Serving Size: 1/3 tsp (1g)

OptiMSM is extremely safe. Extensive toxicology data shows that it can be taken in high doses for a long period of time. Supplementation recommendations are 1/3 teaspoon.  This is equivalent to 1 gram taken twice daily.
