    Simple but it works

    I really like this product because it’s simple. Prebiotic and probiotics.... that’s it. There’s no fillers or additives. It’s super economical and easy to feed. My horse eats it every time. And I have noticed that he cleans up all of his food better when he’s on this product. And that he overall just seems happier and healthier. Highly recommend.
