Product Overview

Which horses benefit from comprehensive hindgut support?

In his natural habitat, your horse would graze most of the day to meet his nutritional needs. As a result, his digestive tract is designed to rely on a slow, steady intake of complex carbohydrates like grass and hay. However, constant access to fresh pasture can be hard to come by and many horses don’t (or can’t) have access to free choice hay. Unfortunately, this along with other common events like changes in hay or grain and increased stall time can contribute to an unhealthy hindgut and lead to digestive upset. That’s why it’s smart to provide every horse with support for a balanced hindgut, as it is critical to their overall health and well-being.

SmartDigest® Ultra Powder is rated 4.6 out of 5 by 801.
Rated 5 out of 5 by from My horse loves it! Only time will tell if this product will have the effect I’m looking for (continued support of my mare’s GI system), but she is eating it, and that is an important first step! She’s pretty picky and wasn’t thrilled about another brand’s product, so I wondered if she were even getting those nutrients. At least I’m assured that she is with SmartDigest!

Rated 4 out of 5 by from So far so good! I've been using this supplement for a little over a month with a horse of mine that is colic prone. He turned his nose up at it at first, but now eats it mixed in his feed. We've had drastic temperature changes recently, which I think has given him trouble in the past, but so far so good!

Rated 5 out of 5 by from Won’t go without! I have tried different GI products and have come back to this one for the quality and results. My horses will not go without this! Smartpak makes it so easy.

Rated 5 out of 5 by from I’ve Definitely Noticed A Difference! I bought my OTTB about 5 months ago and he has struggled with GI discomfort and has been a bit girthy since I purchased him. After two weeks on this, I’ve noticed a huge difference in his gut health and his attitude. He is a lot more relaxed under saddle as well! I will continue to use Smart Digest Ultra in addition to Daily Gold Stress Relief as an additional stomach buffer. Overall, I’m very impressed. The additional colicare is a huge bonus!

Rated 5 out of 5 by from Smart investment My daughters pony has been on this for a month and doing great. He eats the powder as a top dressing on his pellets with no hesitation.

Rated 1 out of 5 by from Horse Refused to Eat It! I tried and tried and tried to get my picky OTTB to eat the powder version of this supplement. He refused, so I have no idea if it would work for him or not. I ended up giving the rest of his month’s supply of SmartPaks to a barn mate so it wouldn’t get wasted, and switched him to the pelleted version to see if that is acceptable to Mr. PickyPony.

Rated 5 out of 5 by from Fixed what my vet could not. Ever since I brought my horse home, she’s had unformed, runny manure. This issue had been chronic for some time before I got her. I worked with my vet and did lots of different things to try to figure out and fix what was causing this issue and the vet ultimately found nothing of note, then informed me it was an “ugly normal” consistency, he wasn’t concerned. Since my vet’s only suggestion was acceptance, I decided to contact the SmartPak team. Based on what I had told them and what my goals were for my horse (and her health), they recommended the Smart Digest Ultra. I was worried my horse may not like it, but she happily ate this. Within about a week, we had solid, defined manure. The horse has been quieter and seems more comfortable now, too. It took about two weeks to see a consistent improvement, but it did for us what the vet couldn’t do: fix the problem. I am more than happy to stand behind something that actually worked. And in the case of SmartDigest Ultra, it worked extremely well.

Rated 1 out of 5 by from NO Effect My horse has chronic diarrhea that comes and goes with the seasons. I saw the great reviews with this product and had very high hopes, but after a month on this supplement his loose stool didn't get any better, maybe even got worse. Very disappointed.

Rated 5 out of 5 by from Helped a kill pen rescue regain his health! I recently rescued a 3yr old saddlebred from a kill pen, immediately put him on this supplement as he was very underweight and had diarrhea from the diet changes. I know so many people who’ve had great success with it. What a difference, he will be on this for life!

Rated 5 out of 5 by from Awesomeness I bought this over a month ago. I’m very happy I did. My psyllium questions of how much and how often are now taken care of. A horse owners life made simpler.

Rated 2 out of 5 by from No change on this product Six weeks in, and no improvement in my horse’s loose manure. She eats it, but sadly it doesn’t seem to help.

Rated 5 out of 5 by from SmartDigest Supplement I purchased this supplement for my mare a few months ago. She eats it happily. I'm relieved to have the peace of mind that she will now be insured through the colicare program!

Rated 5 out of 5 by from Great product ! My horse thrives on it and he loves it. I recommend this to anyone concerned about their horses gut health.

Rated 5 out of 5 by from Wonderful results I feed my 7 Fjords on this and could not be happier. This is the best product I have tried and it stops their loose dung.
Date published: 2020-06-07
Rated 5 out of 5 by from Works just like smart Digest ultra pellets! I had my welsh pony on the smart digest ultra pellets and tried him on this and even though a powder he eats it no problems! He’s a picky eater too, this is only powder supplement he will eat no problems! Even licks his bowl after clean! And save money and still get the colic care! Win win!

Rated 5 out of 5 by from Make better use of feed! My older horses assimilate their rations more completely, staying stronger and in better weight. They are warmer in cold because they have calories to burn and a healthy cat reserve. They retain muscle on the back extending their riding usefulness. No skinny old horses in my barn!

Rated 5 out of 5 by from Great product! Ultra Digest literally saved my stallions life. Two different Vets recommended putting him down due to not being able to get chronic diarhea under control. Doing my own research I discovered SmartPaks Ultra Digest ~ and it worked beyond expectations! Two years later he's going strong, a healthy and happy 23 yr old!

Rated 5 out of 5 by from The perfect mix I really love this product that is proven to help prevent many stomach issues. Smart pak stands behind this product in such an extraordinary way. How could I not trust it? That said, I also love its ease of use and how they package and send it monthly. This product is a win win for everyone.

Rated 5 out of 5 by from Love SmartPaks and ColicCare! I bought these because I wanted to enroll in ColicCare. They auto ship right to my barn so I don’t even have to think about ordering when I run out. My horse eats the powder just fine, though I did switch to pellets just because they’re easier for the folks at the barn to feed.

Rated 5 out of 5 by from Noticed Improvement Have been working on different game plans for Ulcers. Getting just OK results after a month or two. Added SmartDigest Ultra Powder and Noticed a difference in a week and has continued to improve. Both of us are HAPPY with the results

Rated 5 out of 5 by from Finally! I had been trying several different mixes from different places in an effort to get my draft mare's manure more on the solid side of things. Nothing worked until I tried SmartDigest Ultra Powder. It smells delicious and my mare thought so too. It took about 10 days for the manure to have better form, but she had been struggling for a few months with loose stools until I found this, so I did not expect overnight results. Now she will stay on this supplement... So happy!

Date published: 2019-05-10
Rated 5 out of 5 by from My OTTB is almost normal now. When I took custody of my OTTB he was exhibiting all the signs of ulcers. I put him on different supplements and Omeprazole which helped a lot but there was still some issues. I decided to try SmartDigest Ultra. He's been on it for almost 2 months now and the difference is amazing. I've never been able to give this horse a good through brushing without him trying avoid my touch on his right flank especially. He's finally relaxed and allowed me to give him a through grooming. He's always avoided the saddle but he's getting better about that too. He seems way more comfortable and has put on weight. His coat looks fantastic and his farrier has complemented the quality of his hooves.

Rated 4 out of 5 by from Horse seems to be eating and he is super picky I appreciate that Smartpak has a product that is eligible for the Colicare without being super expensive as my horse is a very very picky eater. He seems so far to be eating this and I think that it is a good supplement going into the winter months when he tends to get ulcers.

Rated 4 out of 5 by from His manure has imporved! I have been using this for about 2 months on my daughter's aged gelding. He was experiencing runny manure. The vet even agreed that the ingredients in this were good. His manure returned to normal in about a week and still continues to look good!
Date published: 2018-10-04
Rated 5 out of 5 by from Easy to use Started this shortly after my mare passed. Gives me peace of mind knowing my gelding is getting good stuff for his tummy and protecting my investment!
