Careflex contains 8,000 mgs of glucosamine which is one of the highest amounts among equine joint products. Its unique blend of herbs, vitamins, anti-oxidants and nutrients help to improve flexibility and over all health of joints. What is a hyaluronic acid(HA)? It is a long chained molecule made up of saccharides and glycoaminoglycans. A HA molecule retains water molecules and becomes a gel like substance which provides the lubricating and shock absorbing benefits. HA also helps to bring nutrients to and remove wastes from joints.
