    Rated 5 out of 5 by from Great product A customers horse had very loose manure and has tried a few different products with no luck. Two weeks later, his tail is clean! No more runny poo!

    Rated 5 out of 5 by from Great probiotic! I put my draft cross gelding on this supplement because he would occasionally have runny manure. Within a week or two, he was having nice solid droppings. I was also hoping that this would stop his bad habit of eating his manuer, but it didn't. He is still eating his manure.

    Rated 2 out of 5 by from Not for fussy eaters Bought this supplement for my somewhat fussy mare and she wouldn't eat it. Normally if she doesn't like supplements i can get her to eat them coated in molasses, she still wouldn't eat her grain with the supplement in it, even coated in molasses. Seemed like a great product for price but I cant seem to convince my mare to eat it.

    Rated 4 out of 5 by from Helped I have a mid 20's morgan who has terrible runny stools as he has aged. His tail becomes a mess and it is very difficult in winter to keep it washed and smelling good. I decided to try this supplement as I am very pleased with smartpak and this had good reviews to help loose stools. He has been on it for about 6 weeks or more and while it has not completely eliminated the problem, it has improved the situation to a degree that is much more manageable. He did not want to eat it the first day, and this horse literally eats ANYTHING, but by the second day he ate it no problem...and he hardly gets any grain...just enough to eat the supplement actually. I think this is a great value and will keep him on it as I am pleased with how it has helped him.

    Rated 5 out of 5 by from I'm a believer I bought this product to provide extra support for my mare while she was on antibiotics. Previously when she had been on antibiotics she had issues with loose stool. This problem is no more thanks to SmartDigest! Within days I noticed a huge improvement, and she remained healthy with no issues throughout the course of her antibiotic treatment. I like it so much that I decided to keep her on it full time. I purchased the powder and she ate it right up.

    Rated 4 out of 5 by from Recomended I am glad I am giving my horse supplements, it is so easy and they hardly ever not work. My horse has issues with loose stool, and it is helping, but still needs some more time, since I haven't been using the product for a very long time. But I am pleased so far.

    Rated 5 out of 5 by from Excellent product, super affordable. I bought this for my hard keeper to see if it would work, it immediately made a difference for him. And even better, I bought two big buckets of it during a 20% off sale, so it's only costing me roughly .50 cents a day!

    Rated 5 out of 5 by from Really helps I originally bought this for my horses before the grass came in since they go several hours in between hay/grain. Once the grass started coming in I stop giving it until my senior horse was put on medicine for Cushings Disease. One of the side effects that were effecting him was loose stool and his was VERY loose. I found my self having to hose or rinse his backend down every day and I know it didn't make him feel very good. I starting giving this in his grain before I give him his medicine and we've had GREAT improvement on the stool side.

    Rated 5 out of 5 by from Helped my gelding's digestive issues We got a new gelding Feb 20, and noticed right away he had very loose stool. I thought he was just nervous at first, being in a new barn and all, but it continued. I put him on this, and his stomach has seemed to calm down. No more "splatterings" on the stall walls, lol.

    Rated 5 out of 5 by from It really works! I have had my pony on this for 5+ years. He came to me with extremely wet, gross manure problems, and within a few months of being on this, his problem cleared up. Is his manure perfect? No, but it's no longer constant cowpies. Additionally, my pony is getting older, and with that has come some colic-like episodes. They have always resolved themselves easily, with minimal vet help needed. I firmly believe it is because he is on the supplement. It gives me peace of mind, even though that's hard when he does present with colic-like symptoms. I highly recommend this product to ensure your horse's digestive system is getting exactly what it needs, and you'll feel better to knowing your horse has great protection from colic!

    Rated 5 out of 5 by from Worked like a charm My mare had been having chronic diarrhea pretty much all winter. I had tried several things to correct the problem, both prescription and OTC, but nothing worked. Within 1 week of starting Smart Digest, the diarrhea is gone. She seems more content and I know she has to feel better.
    Date published: 2016-05-09
    Rated 4 out of 5 by from Only Worked On The One Horse I tried three of my horses on this product, all for slightly different reasons. After two months I only noticed a difference in my one mare. She was constantly pooping. Just one or two runny turds and then 10 minutes later she would poop again. Her stall was gross and I would clean up after her 2-3 times just while tacking her up. It was annoying. All of that stopped once I put her on SmartDigest. Her stool is firm and regular and she does not go so incessantly anymore. I will never take her off of it.

    Rated 5 out of 5 by from Very Satisfied for the money I have a finicky mare that gets colicky with weather change, goes off feed in stress. I started a very expensive pre/probiotic and decided to try this for the price and the weather is greatly fluctuating and she is cleaning her feed up 100% and her hay and no issues with the weather change! Very excited for this with her. My other mare gets wet stool not diarrhea but squirts after pooping and now on this she no longer has wet manure! I highly recommend.

    Rated 5 out of 5 by from Approve I bough this for my horse who can sometimes get stressed in new situations. It not only helps keep my mind at ease, but also his stomach. Great for a horse who shows a lot and can become anxious.
