Collagens are a big family of proteins and represent around 25% of total proteins in mammals, including the main protein that forms the connective tissue in all higher animals. Connective tissue contains a mixture of cells, proteins, complex polysaccharides, and inorganic constituents. Collagen, like elastine and proteoglycans, is located in the extracellular matrix. The function of collagen is to give strength and flexibility to the connective tissue. Scientific studies have proven that human cartilage is made up of approx. 60% collagen type II, 15% glucosamine, 15% chondroiton sulfate, and water.

MSM (methyl-sulfonyl-methane) is a pure, organic, nontoxic, nonmetallic element that occurs widely in nature. MSM is a metabolite of the compound dimethysulfoxide, and by weight is 34% elemental sulfur, making it one of the richest sources of sulfur. MSM has been shown to be completely nontoxic in study after study, even in high dosages. In mammals storehouses of MSM decrease with age, possibly due to a changing diet or body metabolism, which is why supplementing your diet with MSM can be so effective.*
