Glyco-Flex is a nutritional joint supplement for cats throughout their lives. It is excellent for all aging breeds that are predisposed problems. It is made from pure freeze-dried Perna canaliculus (Green-Lipped Mussel from New Zealand). It contains all major classes of glycosaminoglycans (GAGs) including Chondroitin -4- and -6- Sulfates. GAGs are referred to as the "glue of life" and make up the core of all connective tissue. The Perna in Glyco-Flex is also rich in amino acids, naturally chelated minerals, numerous enzymes, vitamins, and nucleic acids (RNA and DNA). Glyco-Flex is an exceptional nutritional supplement for the maintenance of connective tissues including joints, synovial fluid, tendons, ligaments, and cartilage.
