It is well formulated, containing all the ingredients found in more expensive brands. My horse is happy with the taste and the instructions for use are clear and simple.

Both the vet and the physio/chiropractor are delighted with the difference in my 21-year-old gelding. He’s starting to stiffen up a bit with age and Best-Flex HA keeps him moving and grooving!

Feedmark are really really helpful, nothing is too much trouble, the supplements are reasonably priced, with great results.
First time on Best flex, very palatable, and I think I'm starting to see an improvements already on two of our mares.

Using Best Flex HA for a number of years now. It is keeping my horses joints mobile. The service from Feedmark is excellent. I like the refill bags option to save on packaging.

Nutrition Information

Maintaining joint health is essential for all horses, particularly those in regular work, older horses, or those competing at high levels. Exercise and the natural aging process can put strain on the joints, making high-quality joint nutraceuticals a valuable addition to support your horse's mobility, flexibility, and overall comfort.

Repetitive concussive forces on the joints are a leading cause of joint wear, contributing to cartilage degradation and synovial membrane irritation. This can trigger an inflammatory response, which, if excessive, may overwhelm the body’s natural repair mechanisms, potentially leading to long-term joint issues.

Best-Flex HA is a scientifically formulated equine joint supplement designed to provide comprehensive joint support. It contains high levels of Glucosamine HCl, Chondroitin Sulphate, and Hyaluronic Acid (HA) - key nutrients that help maintain cartilage integrity and support synovial fluid. MSM is included for its role in supporting tissue elasticity and overall joint function. Additionally, Boswellia offers natural soothing properties, while Omega-3 polyunsaturated fatty acids support a normal inflammatory response. Vitamin C contributes antioxidant benefits, helping to maintain the neutralisation of free radicals and support joint tissues.

By delivering these essential nutrients in an optimal balance, Best-Flex HA® helps maintain joint structure, flexibility, and long-term mobility. Continued daily use throughout your horse’s active career ensures a steady supply of fundamental joint nutrients to support flexibility and performance. For veteran or retired horses, Best-Flex HA® helps soothe the joints and supports ease of movement. It is also safe to feed at increased levels and over extended periods of time for horses that may require additional support.
