Glyco-Flex III Feline represents Stage III of our comprehensive stage of life program for cats needing advanced joint support. These delicious chicken liver flavored chews are recommended by veterinarians for cats with a maximum need for joint and connective tissue support, geriatric cats, as well as a follow-up to orthopedic surgery. GlycOmega Perna canaliculus from New Zealand is from an exclusive source available only to Vetri-Science Laboratories. Perna is an edible species of shellfish that has been freeze-dried in a concentrated powder. It provides many constituents necessary to maintain healthy connective tissue as well as support the cellular processes required for injured or aged joints. Perna is rich in amino acids, naturally chelated minerals, essential fatty acids, glycosaminoglycan"s (GAGs) and vitamins all of which work together to support joint structure and function. GlycOmega Perna contains all major classes of GAGs including chondroitin sulfates and hyaluronic acid that occur in connective tissue such as joint cartilage, tendons, ligaments and synovial fluids. The Perna used in our Glyco- Flex products is time-tested and cost effective.
