My Welsh mountain pony, as very stiff joints, after some research, Best Flex as all the right ingredients my vet suggested, She didn't like the taste at first ,kindly Feedmark sent me some Fussy Feeder for free, things are improving, she's already trying to follow my other mare ,when we go out.

My pony loves this which is a good start! And I already noticed a difference in him seeming more comfortable when ridden within the first two weeks of use. Hopefully it continues long term but after a lot of research, this seemed the only product with all the right ingredients and hopefully worth the price! ☺️

My order arrived very quickly. I would highly recommend the product.  My warmblood is nearly 24 and it has made a big improvement to lifting his hind legs for having his hooves picked out. He is also still moving beautifully.

I contacted Feedmark after my fussy mare refused to eat Best-flex for her joint issues. They kindly sent me some fussy feeder to tempt her. They also advised trying some blackcurrant cordial in her feed for a few days before gradually adding a teaspoon of best flex back in again. This was successful and she is now accustomed to eating it.

Best joint supplement I have found!

I have a 17 year old mare that has severe arthritis in her hind fetlocks and hocks and back in 2019 I was told I may never ride again. Throughout the years I’ve tried so many different joint supplements to not really find any that make a difference until we found best flex! My mare is thriving on this and if we run out I notice a difference!

Highly recommended supplement!

Best flex is the only joint suppliment I can honestly recommend. Having used others in the past, none have even came close to the benefits I have found whilst using Best flex HA. Both of my elderly horses have been on this for years, with my daughters pony even coming off medication for arthritis!
