I am very impressed with this product. I have a retired horse with many ailments and since using this product she feels great and moves like her old self. If I forget her dose you can tell, she’s back to feeling stiff and moving slow. Equiflavin works fast, with 30 minutes you notice a difference. I also give it to my young horse before the farrier. He seams to have more quiet mind and more patience. I have raved about this product to every horse person I know, it works so good.
