    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.

    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.

    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!

    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!

    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!

    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.

    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!
    Date published: 2016-04-07
    Rated 5 out of 5 by from Great Product! My colt was suffering from a hindgut infection that was affecting his overall condition in a drastic way. I tried other probiotics for several weeks with no improvement. One week on Smart Digest and his condition started to improve. His appetite increased, he started gaining weight, and his demeanor also improved. I would recommend this product to everyone!

    Rated 4 out of 5 by from Colicare! Love that it's similar to what I had my horse on before, but cheaper. And it qualified him for colicare. Can't get any better than that. :)

    Rated 5 out of 5 by from Only just started using but my horse love it! Have been on this supplement for a month after a colic issue! My horse loves the taste and I love the reassurance! Can't wait until we are eligible for ColicCare program!

    Rated 4 out of 5 by from Helped My Horse Product seemed to help firm up my horses manure. The Colicare Coverage is a bonus! I did have to switch to the pelleted form because my horse stopped eating the powder.

    Rated 5 out of 5 by from Peace of mind I've had my pony on this for 8 years, and each horse I've had has been on this supplement. It provides peace of mind for me. Any time my horse has had mild stomach discomfort, I don't worry because I know they are on this, and it always works itself out. My pony, in particular, had a severe wet manure problem where it would drip down his hind legs. Ever since he has been on this supplement, he has not had that problem. I've also never had a problem with a horse not eating this supplement either. I highly recommend it, not only for peace of mind, but also for the ColiCare guarantee it provides. Nothing could be better.
