Palatable, prompt service. Hoping my horse feels better as a result. She certainly seems less stuff.

Give it a couple of weeks to work but after that? Amazing! My 19yr old boy is moving so much better and is loving his jumping!

I have been using Extraflex HA for years and probably always will, as it has the optimum level of joint supporting ingredients. It's also very palatable and good value for money.

Nutrition Information

Glucosamine hydrochloride (HCl) and Chondroitin sulphate are well documented joint health ingredients used by the body to help maintain articular cartilage and joint function. These are complemented by Hyaluronic acid, which works within the joint capsule to support the joint and aid shock absorption, and Methyl sulphonyl methane (MSM), which supplies sulphur that is required to provide strength to articular cartilage and has antioxidant properties which helps to mop up free radicals. In addition to these, a generous helping of Rosehips is included in this horse joint supplement, as these are a powerful natural antioxidant for optimum joint health to help with tired horse joints, caused by age or wear and tear. These Rosehips provide naturally occurring Vitamin A, C and K to help potentiate the effects of the nutraceuticals, supporting the horse's formation of cartilage and connective tissue. 

Please note: The number of days each size tub will last depends on the weight of your horse and your chosen feeding rate. The 'Days Supply' indicated in a guideline only.
