    SmartDigest® Ultra Powder is rated 4.7 out of 5 by 722.
    Rated 5 out of 5 by from Summer loves it. The peace of mind I get is well worth it.
    Date published: 2015-12-15
    Rated 5 out of 5 by from Works great!!! My paint gelding has always gotten loose stools in the winter when he is on hay only. I tried several other probiotic products with no success. Last winter I tried SmartDigest Ultra and it worked like a charm. He can be picky, but will even eat the powder without any grain. It kind of smells like maple syrup :) It is a bit expensive, but worth every penny. No more poopy butt in the winter!!!!

    Rated 5 out of 5 by from I love the pre-measured packaging!!!! we put all three of our horses on SmartDigest Ultra Powder 6 weeks ago. I hope to never find out that it is NOT working!! I love the pre-measured packages and my horses love the taste.

    Rated 4 out of 5 by from My mare that is using it is so touchy, can't even change hay fields on her. But, so far so good. We have only been using it a little over a month now.

    Rated 4 out of 5 by from Rebuilt my filly after Doxycycline My Andalusian filly as a foal coliced and was sensitive to antibiotics. As a 2 year old, she contracted Lyme's disease and was placed on a low dosage of Doxycycline, cautiously. The first day she had loose stool, then throughout the duration of the antibiotic she was weak acting, continued a dull coat and looked nauseous for lack of a better explanation. After consulting with Smartpak personnel about halfway through the anti., they suggested the SmartDigest Ultra powder. They recommended the 3.7lb size for a fair amount to see a difference. She just finished the bucket. Her coat came around nicer than I have seen it and her gut sounds are good sounding. She is also 'in the present' acting again. She doesn't love the taste, but will ultimately eat it. Her stable mate, on the other hand LOVES the taste of it and waits to clean up any she may leave behind :) I am dialing this in as a barn staple going forward and will update my review if my thoughts change. I could use the colic insurance from using the premeasured packets (which are supposed to be cheaper than the loose buckets) but the reality is she doesn't always eat the whole dosage and I can give custom scoops to other horses, at will. It probably is not how the product is to be used, but it is my realty.

    Rated 4 out of 5 by from Possibly too soon to tell on the benefits My two horses are boarded at a large facility where the hay is from one supplier but different consistencies with each monthly delivery. Neither have had issues with colic. One horse has constant watery stool that drips from behind in warm weather and the other can be anxious/antsy when hungry. Both are treated with omeprazole frequently. Wanted an all-around supplement to help aid digestion and hind gut health. They have been on this supplement for about 2 months so we may be too soon to see results. Horse with watery stool seems better but the weather is cooler now too. The other horse has seen no change yet. Both horses have no issues eating up the powder. Will continue feeding it for another few months and make a decision down the road on whether it is beneficial.

    Rated 5 out of 5 by from Great Ulcer Prevention I've had my 7 year old OTTB on SmartDigest Ultra for 5 months after treating for ulcers. No gas, loose stools, or any symptoms since starting. It works great for sensitive tummies. She loves the taste so much she licks up any left over! Also like that it qualifies for Colicare!

    Rated 4 out of 5 by from Really helped my horse My horse had a problem with chronic diarrhea and my vet suggested I try this out. It is the only product I have tried thus far where I have seen a significant change in his stool. I would definitely recommend giving it a try if your horse suffers with the same problem.

    Rated 1 out of 5 by from Mare coliced after being on SmartPak Digest Ultra I'm so so sad right now to report that my mare, that has (other than a slight gas colic in July 2009 on a hot day with her foal by her side...) never coliced. I started her on SPDU as a precaution and loved the idea of the Colic Surgery protection. My mare has spend the last 3 days under emergency care with an IV and tube to administer fluids. She is just starting to show signs of a bit of relief. In addition to my mare's colic episode, my best friend, put her mare on SmartPak Digest Ultra (on my recommendation) and she just passed away from colic 3 weeks ago. I'm pulling my horse off SPDU and looking for a new supplement right away. I feel horrible that my poor girl has suffered so much despite spending hundreds of dollars on this supplement over the past 2 years. :(

    Rated 4 out of 5 by from ??? I am mostly reviewing this for the chance to win the $25 gift certificate. I have been feeding SmartDigest Ultra for a month and I assume it is doing what it is supposed to do. He hasn't colicked in the last month but, then again, he has never colicked. I got it mostly cause he is a cribber and I have heard that cribbing is sometimes a response to ulcers. He does still crib, BTW.

    Rated 5 out of 5 by from IT WORKS! My senior mare was pooping regular but small, dark, hard stools. Now its nice and soft and looks healthy.......not to mention she feels great and nickers at the gate for her special mix of goodness.

    Rated 5 out of 5 by from We really like it! I have had my 20 year old OTTB since he was 3, and he's always been a picky eater. I've tried just about everything in the way of various feeds and supplements over the years to improve his appetite but it wasn't until I started him on SmartDigest Ultra that he began nickering to me when he sees me bringing his lunch. That's the meal that has the SmartDigest Ultra in it. He's gained weight and, although I wasn't expecting this to be a benefit, he seems less anxious now. Wish I had started feeding this years ago!
    Date published: 2015-07-19
    Rated 5 out of 5 by from Great Product! I have been using this since 2013 upon the recommendation of my holistic vet. It has made all the difference! When I got another horse over a year ago, I put him on it too.

    Rated 5 out of 5 by from So Far, So Good! I've been using SmartDigest Ultra for about 2 mos now and am very pleased with the results....and YES, I've seen results. My 3 year old was having sensitivity issues to hay after changing barns (first cut vs second cut) and had a bout with very runny cow patties! It didn't take long for his piles to be back to normal once started on the SmartDigest Ultra...Im very pleased!

    Rated 5 out of 5 by from Colic Free! My 25-year old warmblood gelding has been colic prone since he was 5. We have lost count of the number of times he has colic'd - winter, spring, summer, and fall. Since he's been on SmartDigest Ultra, there have been NO episodes! I'm no longer afraid to leave for the day. I only rated the value down as it's expensive for those of us on a budget.

    Rated 5 out of 5 by from awesome product My horse has used this product for a couple of years before I bought him and he still loves it always happy and healthy.

    Rated 5 out of 5 by from All my Thoroughbreds do well on this. Easy to top dress on grain. Seems to help new horses coming in from the track to put weight on.
    Date published: 2015-07-04
    Rated 4 out of 5 by from Good stuff This is pretty okay stuff. My horse isn't picky but it smells nice anyway. Definitely improved his appetite and so far his ridiculously expensive ulcers aren't back, so I'll keep him on this expensive supplement. Pretty much the only downer is that it is pricey. But that's nothing wrong with the product itself.Overall, just good stuff. :)

    Rated 5 out of 5 by from so far, it works! We have been using Smart Digest Ultra for our little Haflinger for the past couple of months and it seems to be helping him. He has had watery poop as long as he's been with us and the Smart Digest is the only thing we've tried that helps him have a more normal poop.
