Manufactured in the body, glucosamine is a simple molecule composed of glucose and an amine (nitrogen and 2 molecules of hydrogen). Physiologically, the function of glucosamine is to stimulate the manufacture of glycosamino glycans, which are key structural components of cartilage. Glucosamine also promotes the incorporation of sulfur into cartilage, making Glucosamine Sulfate the preferred form.

MSM,or Methylsulfonylmethane is a supplement that acts as a sulfur donor, donating sulfur to be incorporated by glucosamine in the formation of cartilage. Without MSM donating sulfur, protein cannot hold its molecular structure nor can tissues hold water. Some other benefits of MSM are in the relief of allergy symptoms, decreasing inflammation, and wound healing.

Vista Natural Wellness Glucosamine/MSM Complex combines Glucosamine Sulfate and Methylsulfonylmethane (MSM) in a highly absorbable, highly bioavailable, formulation. The Glucosamine and MSM complex is NOT derived from shellfish and is suitable for vegetarians and those with allergies to shellfish. It does not contain Chondroitin, due to the complexity of the Chondroitin molecule and the probability that very little, if any, is absorbed from the GI tract.
