Have moved my boy
On to Extra flex, was worried he wouldn’t eat it in his feed as he is very fussy, but has licked the bowl clean since he started taking it so that’s a plus in my books!

My old pony loves it. He seems better for it less stiff in his movements.

Excellent service and easy to order. A palatable product that is great for competition horses. A cost effective product which is a bonus. I’d highly recommend this product and Feedmark too.

Been using this product for a few years now, and have recommended it to friends who are also impressed with the affect it has on their horses.

My older ponies are benefiting from ExtraFlex. Only been feeding for a few weeks but I can see a difference.

I have always used best flex, but decided to try the extra flex HA because feeding three was too expensive now the BOGOF offers have ended, I do think it’s made a difference to the horses they seem more comfortable. It’s early days but I’m going to continue, I wouldn’t say it’s as good as best flex but still good

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, supporting the formation of cartilage and connective tissue.
