Why OptiMSM®?


MSM (methylsulfonylmethane), also known as dimethyl sulfone (DMSO2) and methyl sulfone, is an organic sulfur-containing compound that is essential for optimal health. Without sufficient MSM sulfur in the body, an appropriate level of homeostasis cannot be obtained. OptiMSM® has earned the reputation for the purest, safest, and most consistent MSM in the world.


A proprietary multi-stage distillation process ensures a 99.9% pure product to guarantee a consistent, high quality form of MSM.


The only GRAS-designated, Kosher and Halal certified, non-GMO, gluten-free, allergen-free, non-shellfish-derived, vegan MSM backed by extensive toxicology data.


25+ years of manufacturing expertise backed by ISO 9001:2008 registration, FSSC22000 certification, HACCP and cGMP compliance.
