Working well for my arthritic 31yr old IDX as supplement to meds.

We have recently moved our event horse on to Feedmark Best Flex HA having been recommended this by an equine nutritionist. Having been using the product for 6 weeks we are already seeing improvements in the horses way of going. Wish we had found this product sooner. Highly recommend.

Great product

I researched the highest % active ingredient and feed mark came out on top. My horse has mild KS so I wanted only the best to support him. It’s expensive due to him being a big horse but he’s happy in full work so I don’t plan to stop feeding it.

Great product we notice a big difference if we run out

Quick delivery. Both my horses doing really well on Best flex HA, one has arthritis and really helping him to stay sound

The best Joint Supplement on the market by a long shotà

Waiting to see results. Pony eats it.

Excellent product and service 👍👍👍

My boy looks and feels great on this supplement!
