    SmartDigest® Ultra Powder is rated 4.6 out of 5 by 750.
    Rated 5 out of 5 by from Great Product I have been using this product for 5 years now.. I love it. We have had great results with it. I just changed from the pellets to the powder.. Still great!
    Date published: 2016-10-25
    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!

    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.

    Rated 4 out of 5 by from Great product I was very happy with the value for the price and all of smartpak'a assistance. I sold the horse before she was on it too long so I can't vouch for its long term effects but she ate it and had no digestive issues while on it.
    Date published: 2016-09-07
    Rated 2 out of 5 by from Unfortunately did not help at all with diarrhea. Had no increased benefit over the regular smart digest that I normally use.

    Rated 1 out of 5 by from second colic on this product my horses have been on smart digest ultra for two years. i have never done the packets so i cannot get the insurance but i figured if it was that good it would work and i wouldn't have to use it anyway..right??? my 17.3 hand swedish warmblood coliced July 19th and we had a three day visit to the Tryon Equine Clinic... seemed fine still on smart digest...last night we returned to Tryon Equine clinic with another colic...why am i spending money on this product????? why would i recommend it???
    Date published: 2016-08-22
    Rated 2 out of 5 by from Switched back to GI Ultra My horse didn't like the powder form and the product for her, just didn't seem to help like GI Ultra did which I had been using for a good 6 months prior. She got girthy about two weeks into using this. So we switched back to GI Ultra, which is a pellet and she likes to eat. Everything is good again on GI Ultra. Smart Digest Ultra is probably a good product for some horses, just not mine.

    Rated 4 out of 5 by from I didn't expect much... I'm usually not big on supplements. I'm a big believer that a healthy horse starts with good hay, pasture, grain, and management. However sometimes even with the best care, you still need a helping hand. I have a 24 year old OTTB. After racing in 110 starts and then transitioning into a 7 day a week lesson program, he came to me with a few issues. He was stressed, underweight, bleached coat, and an extremely picky eater. On top of that we were dealing with chronic lymphangitis in both hind legs from day one. With that comes a lot of NSAIDs and antibiotics. SmartDigest Ultra was this horse's saving grace. He went from stressed, dull, and not finishing his grain, to happy, shiny, and fat. Of course a great diet and management did most of the work, but SmartDigest Ultra has helped keep my boy in top shape for his strenous job as a babysitter. He's looking and feeling great, thanks to Smartpak!

    Rated 5 out of 5 by from Good product and customer service Very knowledgeable SmartPak representative helped me select this product to replace another SmartPak product to which my horse had a slight allergy to one of the ingredients. My horse is doing well on this supplement. I especially like that it includes probiotics.
    Date published: 2016-07-25
    Rated 5 out of 5 by from So far, so good... The guys like this stuff, no resistance to it at all. The ColiCare coverage is much more reasonable in real cost than the competition.

    Rated 5 out of 5 by from Healthy Horse!! After my horse had two colic incidents that both put him in a specialty hospital, I was recommended this product. Since he has been on it, I can proudly say that there have been absolutely no colic incidents in the past two years!!! This is amazing for my old guy who used to be very prone to at least one colic episode a year. It took him a week or so to get used to the powder, but now he eats it right up. Thanks SmartPak!

    Date published: 2016-05-17
    Rated 2 out of 5 by from Non-picky eater won't eat it Unfortunately, I recently realized that this powder is what my horse has been objecting to in his feed. I've switched to the pellets for the next shipment as they have fewer reviews indicating that horses won't eat them. My horse has good gut motility normally, I really just provide this as a preventive measure and theoretically for ColicCare. He's not a picky eater, really, but he will completely avoid this supplement in his feed and sometimes actually doesn't eat his feed if it's in there--he will happily eat his feed if it's not there, so I know it isn't the food. I'd hoped to get him switched to the pellets before the next shipment arrived, but I don't know if that will be possible. Hopefully I'll be able to come back here and say that he gobbled the pellets up!
    Date published: 2016-05-17
    Rated 5 out of 5 by from Good product My ottb has been on now for a month and he is liking it . I want to make sure his stomach is working and I feel he starting to finally gain some weight.

    Rated 2 out of 5 by from Great product but unfortunately my mare disagreed My Smartpaks arrived quickly and I was excited to start my mare on them! Unfortunately I couldn't get her to eat this powder, I'm not sure if it was the smell or texture because she usually eats ANYTHING but smart pak was great and let me exchange for pellets which went over great with Zee!
    Date published: 2016-04-24
    Rated 2 out of 5 by from Mare Won't Touch It If I put this is my mare's food she won't even put her nose in the bucket. I'm not a big fan of it being in the powder form anyway and will probably switch to pellets.
    Date published: 2016-04-13
    Rated 5 out of 5 by from Great Supplement! I started my gelding on this when he was 3 years old because when I rode him, he'd immediately lay down and roll. We have determined the issue is linked to him not liking being sweaty, and the fact that he was not in very good shape at the time, which led to his belly issues. This supplement has given me peace of mind and I will keep Lex on it forever!
