Product Overview


  • Dietary Supplement
  • (Methylsulfonylmethane)

MSM serves as an important source of bioavailable dietary sulfur, a mineral that plays a critical role in maintaining the integrity and elasticity of connective and other tissues. It is an important component of proteins found throughout the body, such as in hair, nails, skin and tendons. MSM is a naturally occurring form of organic sulfur found mainly in protein-rich foods such as eggs, fish and lean meat. Taking MSM each day helps to replenish the body's supply of sulfur.

Suggested Use

1/2 teaspoon daily, briskly stirred or blended, with 8 ounces of water or juice.

Part of a list of products currently being used to help combat arthritis in my dog. I prefer iherb products as they are quick to dispatch and their delivery time to NZ is outstanding

Thanks for your feedback!
