One of the best value high spec supplements on the market . Definitely noticed a difference when I started using it

Great product, I've been using it for years and find it really beneficial, particularly for my older horse.

Best ever joint supplement!

My 25 year old mare has been on Best-Flex HA for 5 years now and is still doing all the things she loves including hacking and jumping!! I can't fault the service Feedmark provide or the products I've used.

Mare feels less stiff

Good palatable supplement that definitely makes a difference to how my horse moves! He’s an ex racehorse so suffers with stiffness - but that is considerably better when using Extra-Flex HA!

Been giving this to my 29 year old gelding Oliver for about a year now, his arthritis has improved so much I've been able to take him off bute completely, would highly recommend anyone to give it a go.

6th pot and I wouldn’t use anything else now! Made a huge difference to my eventer

Palatable and noticeable results

Excellent customer service, excellent product.
