Product Overview


  • Science-Based Nutrition
  • Dietary Supplement
  • OptiMSM
  • Promotes Joint Health

Best MSM supplies highly purified MSM (methylsulfonylmethane), a compound notable for its methyl groups (required for numerous metabolic functions) and the conditionally essential mineral sulfur, which is a crucial component of powerful antioxidants such as N-acetylcysteine and glutathione. Although MSM occurs naturally in some foods and in the human body at low concentrations, a significant amount of MSM is lost during the heating and processing of foods.

  • Supports healthy immune response
  • Enhances antioxidant defenses

The MSM used is OptMSM which is a very pure form. That benefit could be lost when additives are added to the capsule, but that is not the case here. Just OptMSM & geltin capsule.

good for more than joints

Posted by AndreaFrankel on Aug 02, 2014

I started taking a lower dosage of MSM as an addition to the glucosamine etc. that I've been taking for my arthritic knee. A trainer told me that higher doses have helped some of his clients with seasonal allergies, so I gave it a try. I take 2 capsules twice a day, and it really does help the sniffles and itchy, runny eyes! When I skip a day, I really notice it.
