    SmartDigest® Powder is rated 4.7 out of 5 by 355.
    Rated 4 out of 5 by from Good product for the price I tried to succeed originally as a digestive supplement for my horse and within a few days notice that he was just generally happier. He was let her thin I tried to succeed originally as a digestive supplement from my horse and within a few days notice that he was just generally happy here. He was less girthy, no ear pinning when you touch him or brushed him. Just better. Succeed however is very cost prohibitive and I wanted to see if it was truly the supplement that was making the difference so I switched to smart digest. I noticed that the grumpiness returned But he still remains collect free and in great condition. For the price I don't think you can beat smart digest but if I really had a problem I would go for the succeed

    Rated 5 out of 5 by from I put a horse on this who just came to me and has had pretty bad ulcer problems in the last few years. He had a mild colic the evening he arrived, and I ran him on 2 weeks of gastoguard, then ordered this supplement. Knock on wood, no issues since and he is looking great.

    Rated 5 out of 5 by from Excellent product with great results I have one of my little minis on SmartDigest and his gut issues, including runny manure, have cleared up completely. I have a little mini mare that had no noticeable gut issues, but who was a bit slow to eat and disinterested in food. She also has a sow mouth that requires dental twice a year. After full veterinary workup and no firm diagnosis I started her on SmartDigest. Within 10 days she had a better appetite and appeared brighter in attitude. I believe that some horses just need that extra gut support and this product provides that.

    Rated 4 out of 5 by from delicate digestion My horse kept having diarrhea even though he seemed to feel fine and nothing in his diet had changed. I tried probiotics, no help. Decided to order SmartDigest and within 2 or 3 days, he was normal. That was more than a month ago and all is still good.

It has helped quite a bit, but hasn't eliminated the problem. Will go through the month, and I figure that should tell whether to keep him on it or not.

    Rated 5 out of 5 by from Great for my Cushings Horse I have a 31 year old quarter horse that was dx with Cushings at age 10. Everything was fine up until a couple of years ago when we added a prescription to his diet to control the symptoms of Cushings. He his appetite all but disappeard and he lost 200 pounds. We all know how hard it is to put weight back on a horse, but a horse that is older with Cushings seemed impossible! We were thinking of having to put him down before winter, but decided to add Smart Digest and Smart Pituitary as a last resort. We took him off the prescribe medication as it read one of the side affects was loss of appetite. We started the Smart Paks and immediately his appetite returned! Nothing is better than watching a horse eat again!! He has slow put back on about 100 pounds which seems like miracle. He has shed about 80% of the hair, drinks and eats well and the future looks good. He has had no problems, and eats all of the supplements! You won't be wasting your money! Thank you Smart Pak for giving my horse a second chance! (I've also posted this on the SmartPituitary page.

    Rated 5 out of 5 by from Wow! I couldn't believe it worked! I am not one to think of a supplement as a cure, but this was part of the answer! When my little gelding had developed a consistently loose stool from finally starting on pasture, I called the vet a bit worried. We had transitioned him over to it gradually, but it was still a bit too rich for his system. The vet tossed out several suggestions, but said start with the mildest treatment: A prebiotic (not so much a probiotic). Specifically, hammered home good yeast content. I immediately got on SP and added one for the next shipment which was many days off, then, to get us through until then, went to a brick-and-mortar store and picked up a bag of a big brand, highly regarded probiotic. That one worked - if I kept him on double dosage. And even then, while improved, I wouldn't say his manure ever firmed up how I would like it. If I missed a dose, or tried to revert to the recommended dosage, we were right back to loose again.I finally got my SP shipment and started him on this SmartDigest instead. Wow. Four days and he was PERFECT. His attitude even changed for the better. He was feeling and looking good on this. The barn manager even was impressed and has asked for more information so that he may recommend it to others who also experienced what we did. I was very pleased overall.

    Rated 5 out of 5 by from Happier horse My horse has had occasional gas colic, and he used to insist on stopping to poop. Now he can poop while walking, and hasn't had gas colic since I started him on SmartDigest. And he's happy to eat it, which is nice!

    Rated 3 out of 5 by from Not all picky eaters like this.... My horse is not a picky eater per say, but is very suspicious of new supplements in her meal. She is not crazy about this supplement thus far and I am hopeful she will start to eat it. I've tried wetting it and adding it to her beet pulp in the PM but she just stopped eating her dinner and other supplements. Now it goes in her AM ration and she is not thrilled. Fingers crossed she changes her mind. It smells great so I am not sure what her problem is.

    Rated 3 out of 5 by from STARTED OUT GOOD This is the second time I have used this product. My elderly horse has chronic diarrhea which makes a formerly over weight horse under weight. It cleared it up after about a week, but it has come back, though not as bad. Sprinkled over his sweet feed he eats it with no problem. I am hoping with continued use it well clear him up so he can gain more weight.

    Rated 5 out of 5 by from Great product Smart Digest was recommended to me by a respected trainer. It had worked well with a couple of horses with mysterious hind gut issues. My horse's intermittent loose stool is pretty much a thing of the past. The longer he is on Smart Digest the better his digestive system seems to work. Thank you for having a great product.
