Been using Best Flex HA for just a couple of weeks.  Horses appear to be moving better and also more relaxed.  Very quick delivery and easy to navigate website.

My horse uses Bestflex and I really notice a difference he’s a 20yr old warmblood that thinks he’s still 10yrs old! Great company to deal with and always prompt delivery

Excellent product. My horses are happy to eat it even if they are fussy about other products. It has really helped our ROR and elderly pony who has arthritis.

I wasn’t certain this product was as good as it sounded! I stopped using it and tried others instead, which made me realise just how much better Best Flex HA is, than any other!
I can’t recommend it highly enough it is excellent!

Excellent product, definitely notice the difference supporting my horses joints and the way he moves. He has arthritis and it’s helping him keep well and still out competing dressage. Would not use anything else!

I’ve got a big boney youngster who was quite stiff when I brought him, although it’s expensive and I have to feed quite a bit as he’s big I’ve noticed subtle changes and I would like to put it down to this!

I use Best Flex HA on both my horses . I use it as a preventative on my three year old and for support for my older horse who appears much more comfortable since I’ve started him on it .

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.
