    SmartDigest® Ultra Powder is rated 4.6 out of 5 by 737.
    Rated 2 out of 5 by from Didn't do much, then my horse stopped eating it. My horse was eating this fine for a while, but I saw no improvement in his moderate dietary condition. He then stopped eating it. Do not waste your money on this, just go with the basic SmartDigest.

    Rated 2 out of 5 by from Unpalatable, not for fussy horses Bought this supplement for my somewhat fussy mare, normally I can get her to eat powdered supplements she doesn't like with molasses, she wouldn't even eat this one with molasses. Seems like a great product for price but i cant convince my mare to eat it.

    Rated 5 out of 5 by from Works great for my OTTB mare I bought this so I would get the Hind gut supplement plus the colicare coverage. However I think my mare is now eating better than ever and I hear her stomach all the time! I love this product. She eats it on dry grain or in her mash. I recommend this product to everyone I know !

    Rated 5 out of 5 by from Great Peace of Mind I bought a Friesian and many are sensitive to change and colic very easy. Thanks to the SmartDigest Ultra Powder, my guy has never looked or felt better. Thank you for offering a peace of mind.

    Rated 3 out of 5 by from Haven't made a final decision on it yet My horse has been on it for 5 1/2 weeks. I've seen some improvement of his loose stools but hoping to see more improvement in the next few weeks. I'll update this then.

    Rated 5 out of 5 by from Happy Tummy Now This product actually works! My very sensitive thoroughbred had a tendency to colic after ever show, after every change in weather, or short period of not being out. Since he's been on this we've have 4 rather dramatic weather shifts, a rated show, and a week of not being to go out, yet he hasn't even had a grumbly tummy. This stuff really has helped him!
    Date published: 2017-01-25
    Rated 1 out of 5 by from combination pre and probiotic I had just read an article suggesting that prebiotics were more beneficial than probiotics for horses. Your product combines both and provides colic insurance to back it up.

    Rated 5 out of 5 by from Love this product and SmartPak Started with the Ultra Powder in pail and within 4 days the loose stools were normal! Decided to order SmartPak and take advantage of the ColiCare program. These are great all measured and easy to open even when it's very cold with glove:))

    Rated 5 out of 5 by from Excellent product! Shortly after purchasing my mare she started having loose stools and fecal liquid so bad it ran down both legs but no temperature or other signs of illness. My vet did a diarrhea PCR panel test, fecal test and blood test and also checked for sand but all came back negative and he suggested a Pro/ Prebiotics product , which I did but was still not having normal stools and fecal liquid amounts varied from just a little to a small stream..then I started her on SmartDigest Ultra Powder 11/19/16 and with a few days her stools are normal and no fecal liquid!!!! Since this was about the third product I had tried, I decided to start by purchasing the 28 day bucket, but after seeing the results I ordered the SmartPaks to take advantage of the ColiCare protection. Oh and my mare loves it too!! Thank you SmartPak I love this product:)

    Rated 5 out of 5 by from My horse LOVES this stuff! I'm so happy to have my gelding on SmartDigest Ultra powder. It's a huge relief to have him receive such a high-quality digestive health supplement and be covered under Colicare to boot! He's a picky eater yet loves eating this powder. Even I think it smells pretty good myself! ;)

    Rated 5 out of 5 by from Piece of MIND!!! Worth its weight in gold. When you get the call or the visit that results in surgery as the only option, you can rest easy, Smartpak has you!

    Rated 4 out of 5 by from Well worth it I feel protected knowing if my horse needs colic surgery, he is backed by colicare. It's like colic insurance for your horse.

    Rated 5 out of 5 by from World of difference! This product makes a huge difference in a horse who we have tried every ulcer medication on the market with. We have switched every horse in the barn to it!
    Date published: 2016-10-20
    Rated 5 out of 5 by from Life Saver After treating my OTTB for ulcers, I needed a preventative supplement for her. She's been on the SmartDigest Ultra for well over a year now with excellent results. No gas, no pain, solid stools. I was weary of using a powder but my mare will lick any leftovers in her bucket. I highly suggest this product. Plus having the reassurance of Colicare is great.

    Rated 5 out of 5 by from Effective for digestive issues My mare has been on SmartDigest Ultra for a month now. No problem with palatability - she seems to like it. The product has significantly reduced her issues with intestinal gas.

    Rated 5 out of 5 by from Like it so far! My horse just tested positive for hindgut ulcers and was showing signs of overall discomfort. He has been on this for a little over a month and has already shown a change in attitude and seems to be feeling better already! So far we are VERY pleased with this product!
    Date published: 2016-09-26
    Rated 5 out of 5 by from Excellent Product I started my competitive trail horse on Smart Digest Ultra a few years ago after he ended up in the hospital and was diagnosed with gastric ulcers. He was treated for the ulcers and they cleared up, but he was always an anxious horse, worried about everything, especially the trailer, and he had a hard time gaining and maintaining weight. After starting him on Smart Digest Ultra his nervous diarrhea improved, and his ability to gain and maintain weight also improved. Sadly, I lost him suddenly and unexpectedly to an allergic reaction. Now I am using Smart Digest Ultra for my three year old filly that has recently begun traveling. I want to prevent any problems due to the stresses of traveling, and keep her healthy. I believe Smart Digest Ultra will help me to do that!

    Rated 4 out of 5 by from Easy to feed, horse loves it As with anything digestive, it's difficult to tell if it's working correctly. However my horse loves it, it gives us the quality of mind with ColiCare and he is happy and healthy.
    Date published: 2016-09-20
    Rated 5 out of 5 by from Great product I've been using this for over a year and a noticeable difference with one gelding - in that he seems happier and is cleaning up his grain and hay.
