## Overview

Cox Veterinary Acti-Flex 4000 Gallon is a scientifically formulated liquid supplement combining Glucosamine, Chondroitin, MSM, Boswellia Serrata, and Hyaluronic Acid to support and repair horse joints by boosting synovial fluid production, reducing inflammation, and strengthening connective tissues.

## Description

Acti-Flex 4000 has an advanced, fast-acting, 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 Acti-Flex 4000 they, and other key ingredients work together to improve performance by increasing the horse's supply of joint-lubricating 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, Acti-Flex 4000 speeds the body's self-repairing 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. Feed 2 ounces per day for the first 5 to 17 days then reduce to a maintenance dose of 1 ounce per day. Mix into regular feed or administer via a dosing syringe. The gallon size provides up to a 128 day supply for one horse. For Horses only. No longer contains Type II Collagen

Review: Acti flex works! - We have used this for a year and the horses love it better than similar products on the market. We compete in rodeo events and Actiflex helps protect our athletes.
Review: Awesome stuff! - This supplement does wonders for my 16yr old QH gelding. I had tried every supplement you could think of.. literally.... and none of them gave me the results I was looking for. This is the cheapest supplement I tried and I am finally seeing good results. I highly recommend for any horse who is stiff or experiencing joint problems. My guy was very stiff in his rear legs this winter but since I've had him on this, I've noticed he's much more fluid in the back. He's also picking up his feet much more eagerly. I did try to give a small bit to my dog (7yr old pit who's had two TPLOs) and he turned his nose up at it. He wouldn't come near it. I don't have any issues with my horse eating it however.
