Acti-Flex Powder is the alfalfa-based powder version of the Acti-Flex 4000 Liquid. It contains the same key ingredients to support the joint function of your horse. -Chondroitin Sulfates, increasingly accepted as the most effective treatment for joint cartilage, connective tissues and blood vessels, maintaining their strength and elasticity while fighting inflammation and pain, all without undesirable side effects. - Type II Collagen is the major protein found in cartilage and is the newest ingredient we have added to our family of Acti-Flex products. Type II Collagen is the "glue" that holds cartilage together as well as providing elasticity within the joints. - Hyaluronic Acid (HA) plays a critical role in maintaining healthy joint synovial fluid and preventing the deterioration of aging, over worked joints. HA has a high daily turnover so large amounts are needed to maintain proper levels within the joints. HA is also shown to influence cell movement, blood vessel formation, critically involved in healthy wound healing and serves as an antioxidant. While Acti-Flex Powder works to fight inflammation and pain, it also supports long term protection to knees, backs, stifles, hocks, fetlocks and other cartilage. It helps to prevent much of the cumulative cartilage damage that eventually shortens the animal's prime performance years. Guaranteed Analysis Per Oz: Glucosamine Sulfate 8,000 mg.
