    SmartDigest® Ultra Powder is rated 4.6 out of 5 by 751.
    Rated 5 out of 5 by from Finally found a supplement that works I have struggled for years to put and keep weight on my horse. We struggled with weight lose, periodic loose stools and poor appetite. Its been 1 month on smartdigest and Eve looks like a different horse.. She looks the best she has in many years.

    Rated 5 out of 5 by from Great results My mare began to experience episodes of gas colic as the weather became hot this summer. After an expensive vet visit, a friend recommended that I try SmartDigest. Since feeding the SmartDigest to my mare, she has experienced no gas colic. My mare and my budget thank you!

    Rated 5 out of 5 by from Major changes in my horse! Happy customer! I've had my very heavy cribber on this supplement for 8 months now. He's never colicked but would get significant gas episodes to the point he'd stop eating and start rocking in his stall. I was very afraid colic was our next step. Since putting him on this supplement he has had no gassy episodes. He still cribs like a demon but he's much more comfortable on a daily basis thanks to SmartDigest!

    Rated 5 out of 5 by from Performed a miracle My 11yo gelding had an issue with sand ingestion prior to my owning him. I had him for 3 months, gave him a sand treatment and he ended up with months upon months of various forms of diarrhea. Vet gave him mineral oil and Metamucil to move more sand out. Afterwards the diarrhea got better but he had an issue with this disgusting wet gas that would trickle down the backs of his legs. After more months of Metamucil treatment, I decided to try SmartDigest ultra powder. I was floored to find this issue virtually disappeared after *2 weeks*. I was expecting two months for his system to adapt. I couldn't be happier with this product!

    Rated 5 out of 5 by from Love This! I've had my horse on the SmartDigest powder for about 2 years and recently upgraded to the Ultra. The difference is amazing, the transition to the spring grass this year seems easy. I'm not as stressed because of colic. My horse has not showed any signs of colic since we upgraded. This product is definitely worth it!

    Rated 5 out of 5 by from such a great product! My horses LOVE this stuff. They eat their grain better, and DIVE in to breakfast and dinner with real gusto! I have a bit of a picky eater and this has been his "chocolate". The effects on his digestion seem to be excellent. Of course it's always hard to tell "what one thing" made the difference when you feed multiple items,BUT he seems much more content and is eating and passing stool normally. (ALL VERY GOOD!)
    Date published: 2017-05-05
    Rated 5 out of 5 by from Great product that works! I started my gelding on this over a year ago. At the time he would have intermittent diarrhea for no apparent reason (no stressors, change in food, etc..) I had tried other products with nothing helping or it was only a short term fix. Since beginning the SmartDigest he has had consistent stools with no issues what so ever. It is also part of the ColiCare which is very important to me. I would definitely recommend this to anyone

    Rated 5 out of 5 by from Results for Ziggy are showing! I started Ziggy on SmartDigest a few weeks back and I am impressed with how fast the results were! Within a week he went from projectile liquid diahrrea to normal manure piles - and he continues to have normal piles. Much happier horse and owners!

    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 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 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:)

Even I think it smells pretty good myself! ;)
