    PrePro is High Quality Probiotics

    Posted by Paint Farm on 30th Mar 2020

    Our horses have used PrePro when needed for a few years now, and we are very happy with the results. We have used at times of extra stress, during/after antibiotics, any signs of digestive upset. PrePro is clearly a high quality substantive probiotic! We recommend it to others.

    I especially like the addition of enzymes in this product as one member of the herd was just prescribed it. Win-Win!

    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.
