My horse has been on Extra Flex HA for many, many years and now at the grand age of 26 he is still on it and even though I retired him 6 months ago he will stay on it as I believe that it is essential for his joints especially as he is ID X and therefore a large solid horse - but nice with it 🤣

I have used this supplement for years for my horses. It’s very high quality and you can really feel a difference when a horse goes onto it.

Delivery time is brilliant… I always leave it too close to the end of the tub to order. My competition horse is currently out of work lame, but will stay on this product through her rehab! Great product.

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.
