## Description

ActiFlex 4000 has an advanced, fastacting, liquid formula of Glucosamine, Chondroitin, MSM, and Superoxide Dismutase. These ingredients occur naturally in the body, serving the function of repairing joints and many other tissues. In ActiFlex 4000 they, and other key ingredients work together to improve performance by increasing the horse's supply of jointlubricating synovial fluid, which repairs and strengthens stressed body parts.MSM adds a powerful ability to improve sulfur bonds, which are an essential component of all connective tissue. Ascorbic Acid (Vitamin C) is a key to optimizing bio availability of the other ingredients, as well as being an essential antioxidant. Boswellia Serrata is an herb that is proven to reduce inflammation. 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. By supplementing what a horse produces for itself, ActiFlex 4000 speeds the body's selfrepairing processes. Guaranteed Analysis Per oz. Glucosamine Sulfate 8,000 milligram. Chondroitin Sulfate 4,000 milligram. MSM 3,000 milligram. Ester C (Ascorbic Acid) 1,000 milligram. Yucca 150 milligram. Hyaluronic Acid (HA) 125 milligram.
