Changed to Best-flex HA from Synequin for my 30yr old IDX, as included more elements for arthritis management. Seems to be working well alongside prescribed meds.

Started the supplement, initially my horse was a little put off by the smell as it's quite pungent. However we introduced slowly and he is up to half the recommended daily intake. Too soon to tell whether it's making a difference as we are increasing the exercise alongside.

My horse has definitely seemed more comfortable & consistent in their health & performance since taking Best-Flex supplement.

Best Flex H is the best working supplement I have found for my mare. The difference it has made is amazing compared to other more expensive brands. Quick delivery also from the Feedmark

Great delivery service. Been using Best-Flex HA for about a month now on my 28 Welsh Section D and can notice a difference when riding him.

This is my second order of Best Flex HA. I think it is helping my 17 year old with his arthritis and joint flexibility.

Very palatable, it's early days so waiting to see the real benefits

I am over the moon with the positive effect that Best Flex has had on my mare. We’ve been struggling with her tendon sheath but I am noticing such a difference since we have gone back to this supplement, no others have made a difference.

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.
