Senior horse is pain free!

It is an excellent product!! I have a senior horse with arthritis and this stuff is a miracle for him all year round but, especially during the cold Midwest winters. My faster asked what I was giving him because he is not still and cranky anymore. I highly recommend it!!

Love This Product

I see a marked improvement in the movement of my older horses when they are on this joint supplement. It really helps maintain their movement and deals with stiffness of joints. I highly recommend Grand H.A. Synergy.

Excellent results

I have been using this product for years on several horses and have always seen excellent results. One horse has sticky stifles. If she goes off the supplement, her stifles will lock. This supplement keeps her sound.
