So my 22-year-old quarter horse has been on this UltraCruz joint supplement for about three months now and I'm seeing a real difference in his mobility. He moves more freely coming out of his stall in the mornings and seems more comfortable during our light trail rides. The 4-pound container lasts forever since you only need to feed a small amount daily. What I appreciate is that it's soy-free, which is better for horses with sensitive systems. The powder mixes well with his grain and he actually eats it without picking around it like some supplements. I've noticed less stiffness after he's been standing in the cross-ties for grooming too. It's specifically formulated for senior horses, so it addresses the unique joint issues older equines face. The ingredients support healthy connective tissue and joint integrity without any weird fillers. If you have an older horse that's starting to show their age in their movement, this supplement is definitely worth trying. Much more affordable than some of the big-name brands but seems just as effective. My farrier even commented that he seems more balanced and comfortable during his last shoeing.
