    SmartDigest® Powder is rated 4.6 out of 5 by 362.
    Rated 3 out of 5 by from STARTED OUT GOOD This is the second time I have used this product. My elderly horse has chronic diarrhea which makes a formerly over weight horse under weight. It cleared it up after about a week, but it has come back, though not as bad. Sprinkled over his sweet feed he eats it with no problem. I am hoping with continued use it well clear him up so he can gain more weight.

    Rated 5 out of 5 by from Works Purchased this for my AQHA mare who is a senior and has a tendency to get gas and have loose stools.Smart digest helped with that and my mare gobbles it right up.She is not a picky eater though.

    Rated 5 out of 5 by from Great product Smart Digest was recommended to me by a respected trainer. It had worked well with a couple of horses with mysterious hind gut issues. My horse's intermittent loose stool is pretty much a thing of the past. The longer he is on Smart Digest the better his digestive system seems to work. Thank you for having a great product.

    Rated 5 out of 5 by from Great results!! My horse has improved dramatically since starting him on smart digest! Within days his loose manure was subsiding and he was better behaved under saddle. I plan to keep using this product as it seems to be very beneficial and making my guy happy!!

    Rated 5 out of 5 by from Palatable and so far good results I wanted to try a new probiotic for my boy. He's been on smartdigest for about 3 weeks and he's started to put on weight! I was concerned he would turn his nose up at it but he's been licking his bowl clean!! I'll definitely be ordering more

    Rated 5 out of 5 by from Offers peace of mind I decided to try SmartDigest, just to cover my bases and offer digestive support (can't hurt). My mare finds it palatable, and though it's difficult to tell how it's working internally since she wasn't symptomatic, I've noticed that she's much less gassy.

    Rated 5 out of 5 by from Great for my gelding My gelding had been dealing with off and on loose stool for about 3 months. I was told to try this product by my boarding facility. Sure enough! It worked! No more loose stool. He is actually a picky eater but he eats this stuff right up!
    Date published: 2015-03-11
    Rated 3 out of 5 by from She was not impressed I liked the product but unfortunately my mare wouldn't eat it. It seemed like a good mix but something about it put her off both it and her feed (and her other supplements). We had to work hard to convince her to eat it, enough so that it really wasn't worth the effort.

    Rated 5 out of 5 by from smells wonderful while it does its job I tried a couple of gut supplements before this one, and no one would eat them. They smelled foul. This smells good enough to eat, and therefore it's easy to get in the horse, so it can have a chance to do its work. I am using this for support, not necessarily for a problem, so I can't say that it "fixed" but it's helping my older horses keep weight through this brutal winter so I'd say it's a win!

    Rated 3 out of 5 by from Worked with My last horse not so much my new horse I bought this over a month ago for new horse after it worked so well with the last horse I had. I never had a problem with my last horse when he was on this supplement. About a week ago my horse started to colic in her stall she came around right away and I never needed to call the vet. We have been having done crazy weather at the barn latetly so that might have been why she started to colic. This supplement might have been why she came around so quickly. It would be easier if she could just talk to me but I will keep her on it because it has worked so well for me in the past.

    Rated 5 out of 5 by from smart digest is a smart choice I have used this product on two of my horses, One is a horse I use for cow work and she travels often.. she has a propensity after traveling to have mild colick symptoms. Since I started her on Smart Digest she has been symptom free, even after long hauls and new settings.My other filly is a TB off the track who definitely had ulcers and I believe that this product, Smart Digest has helped her ulcers heal more quickly and has kept her well and ulcer free. I highly recommend this actually for any horse, keeps their digestive tract healthy which directly relates to a healthier immune system

    Rated 4 out of 5 by from Great Product I decided to try smart Digest for my horse with ulcer issues. He is already on smart gut. He ate this up well and seemed to do quite well. No loose manure at all!

    Rated 5 out of 5 by from I have tried several others from here and this is the only one that finally worked. Although I have to feed a bit more than the recommended dose as my horse been diagnosed with Inflammatory bowel disease, the higher dose works for him. I may try to reduce the amount at some point in time.

    Rated 4 out of 5 by from have to wait and see Haven't been feeding this long enough to know how it will do, but my horses find it palatable, which is a good start!

    Rated 5 out of 5 by from Worked perfectly! My filly has always had a bit of runny manure. We had tried so many different things but nothing worked. Being a dominantly white mare and a gypsy you can see where this could be extremely frustrating. She is also incredibly picky and is next to impossible to sneak anything in. However with Smart Digest this was not necessary. Not only did she eat it with no problem it worked pretty quickly. The results were undeniable. My filly will always be on this product. Thank you Smartpak! Will continue to recommend this product to my friends!

    Rated 5 out of 5 by from Good for the sensitive types I bought Smart Digest for my sensitive 5 year old Swedish mare after she had a bout of mild compaction colic and seemed a little gassy several months afterwards. Since starting her on this supplement, she has seemed much happier and her excessive flatulence is nearly gone. Thank you SmartPak!

    Rated 5 out of 5 by from Very pleased with this product I've used SmartDigest in the past and recently have started my little 13 year old mini horse, Mokey, on the product. Mokey suffers from loose stool and I've found that SmartDigest helps him and the stool is much more normal and he's less gassy.

    Rated 5 out of 5 by from 5 star product I used this on a mare who had to be on stall rest. She was really nervous about being stuck inside and developed diarrhea. I decided to try SmartDigest. My mare cleared up in a couple days! It worked really well for me in this situation. I was afraid she wouldn't eat it as she only got a handful of grain but she would eat the powder without anything! I would definitely use it again!

    Rated 5 out of 5 by from Love this product I actually only began using this product a week ago and my horse has made an incredible turnaround.My horse started having explosive, watery stools in August. I wormed him, gave him psyllium and probiotics. Nothing helped. His stools got worse and worse. His backend and tail were constantly caked with feces. I was worried sick with what to do. My vet didn't want to come out because he was eating normally and hadn't dropped an ounce of weight.I happened upon this product and thought I would give it a try. I noticed a difference in his stools after 2 days. One week later everything is firm and back to normal. Thank you , thank you, thank you!I actually mix it with about 7 cc of water so it's the consistency of good brown sugar. My horse eats it out of my hand.
