GLYCO-FLEX II EQ for horses is a supplement to support proper joint and connective tissue functions. This formula includes Perna canaliculus, Glucosamine, and Methylsulfonylmethane to provide optimal connective tissue support. The Perna mussel is rich in all the major classes of glycosaminoglycans (GAGs), including Chondroitin - 4 - and - 6 - Sulfate as well as amino acids, polypeptides, and nucleic acids (RNA and DNA). Its effectiveness as a supplement is due to the unique biological activity of all the many identified factors in the Perna Mussel. Methylsulfonylmethane ensures the bodys ability to synthesize collagen for connective tissue health, maintain cell membrane flexibility, and promote cell regeneration. Glucosamine gives shape, elasticity and rigidity to such tissues as cartilage, tendons, and ligaments and provides a key building block to the synthesis of cartilage.
