Glyco-Flex® EQ for horses is a nutritional supplement to support proper joint and connective tissue functions.* 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® EQ is also rich in amino acids, naturally chelated minerals, numerous enzymes, vitamins and nucleic acids (RNA and DNA). Glyco-Flex® EQ is an exceptional supplement because it can effectively support the maintenance and repair processes of connective tissues including joints, synovial fluid, tendons, ligaments and cartilage.*
