I am very impressed with  Extraflex HA. I was looking for a joint supplement and chose this as my horse has done so well with Clarity. Would recommend both products.

My competition horse is coming mid teens and just needed that extra bit of help in her work load. I have noticed a difference in her way of going. Great product!!

I’ve been using this product for some time and highly recommend it. The horses find it palatable and it’s used for 2 dressage horses. As well as supporting the horses joints it is good value for money.

Have used Extra Flex for a few years now after it was recommended by a McTimmony practitioner.  My horse had a slight stiffening of his right hock.  He has been on it ever since.  The same McTimmony practitioner says his hocks are now fine and there are no signs of any stiffness.  Plus, it makes his boring chaff breakfast taste nice and he never turns his nose up at it.

I have used Extra Flex HA for many years, as the owner of a 16 hands 3” ID X I always want the best for him and his joints and I believe that Extra FlexHA fits the bill.  He is now 26 and has just recently retired and is enjoying life and will continue to have Extra Flex in his feed.

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, a powerful natural antioxidant for optimum joint health to help with tired 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, optimising the formation of cartilage and connective tissue.
