I have been using this stuff on and for for years as my horses need it. Great for general maintenance if you ride regularly and just as great for arthritic horses. My old man (33yrs) moves like a youngster on this stuff. My 13yo mare had a slight hitch in her giddy up when working tight circles. After 2 weeks on this product she is moving soundly and seems more comfortable. It’s very palatable for the picky eater and very effective. I’ll continue to use and recommend this product!
