    SmartDigest® is rated 4.7 out of 5 by 378.
    Rated 5 out of 5 by from Fantastic Results I added the SmartDigest Powder to my horse's SmartPaks a month ago and already I've noticed incredible results! He has always been an extremely picky eater and often I would have difficulty even getting him to finish his grain at all. Now he can't wait for his meals and is begging for more! Thank you SmartPak!! As always, you've saved the day. We use you for everything and have always been so thankful for the amazing customer care you provide ❤!

    Rated 5 out of 5 by from I’m Love it I have had my horse on this product for a little under six months and I love it before he showed irritation and sensitivity to the hind guy area. After being on this product for a while he stopped being so agitated and much more happy and healthy ;) Joey is a active show horse and never goes a day without his smart digest I love it!!

    Rated 5 out of 5 by from This product is a wonder I have reviewed this before but I am still 100% happy with it. My old mare is happy and healthy on it. Having her around( even years into retirement) is precious to me. I am thankful for my friend who told me about it.

    Rated 4 out of 5 by from Helps My mare wasn't finishing her food. We had her teeth checked and they couldn't find any problem. Changed grains and it didn't help. Turns out she just had trouble digesting her food. A couple of weeks on this and she finishes all her grain.

    Rated 4 out of 5 by from seems good My mare has had a finicky stomach, and it is always hard to tell whether it is a change in hay, if she is in heat and restless, etc. She has been on Smart Digest for a month as an addition to her other Smartpak supplements, and it so happens that her stomach is more settled. I am going to keep giving it to her.

    Rated 4 out of 5 by from Smart Digest Works! I'm partially through my first order of Smart Digest and I've seen an excellent change in my horse's manure. It is normal now and before was more of a cow patty.

    Rated 5 out of 5 by from Fantastic Product I have a 8 year old mare that developed diarrhea(soft) this summer. I was concerned because her stool had been normal up until the hot weather came. I bought the horse from a girl friend and neighbor who gives SmartDigest Powder to her horses and she had given this to Chase. I ordered some and am very pleased with the results improving after a month mostly normal stools. Chase also a little cinchy during her diarrhea and now back to normal. Happy Horse Happy Rider!

    Rated 5 out of 5 by from Simplicity at its finest! I had added this supplement to my horse's SmartPak to give his hindgit some support. Didn't think my horse really needed it but I have noticed a difference in him since starting it.

    Rated 2 out of 5 by from Horse went off his feed I decided to try this on one of my race horses when he started back jogging. Because of stress, they prone to gut issues, and I wanted to take a preventive measure. Unfortunately, he did NOT like this stuff @ all. At first he picked around it, and after about 10 days of giving it to him (I got it in SmartPaks & split the daily dosage over his three meals) he went completely off his feed. I ended up stopping it so he would go back on his feed. I opted to put him on Sentinel Performance grain, alfalfa pellets and whole plain yogurt instead.

    Rated 5 out of 5 by from Great probiotic! I put my draft cross gelding on this supplement because he would occasionally have runny manure. Within a week or two, he was having nice solid droppings. I was also hoping that this would stop his bad habit of eating his manuer, but it didn't. He is still eating his manure.

    Rated 2 out of 5 by from Not for fussy eaters Bought this supplement for my somewhat fussy mare and she wouldn't eat it. Normally if she doesn't like supplements i can get her to eat them coated in molasses, she still wouldn't eat her grain with the supplement in it, even coated in molasses. Seemed like a great product for price but I cant seem to convince my mare to eat it.

    Rated 5 out of 5 by from Worked perfwctly Solved an issue of intermittent watery discharge along with solid stool. No more dried stool in tail! Healthier happy horse.

    Rated 4 out of 5 by from Helped I have a mid 20's morgan who has terrible runny stools as he has aged. His tail becomes a mess and it is very difficult in winter to keep it washed and smelling good. I decided to try this supplement as I am very pleased with smartpak and this had good reviews to help loose stools. He has been on it for about 6 weeks or more and while it has not completely eliminated the problem, it has improved the situation to a degree that is much more manageable. He did not want to eat it the first day, and this horse literally eats ANYTHING, but by the second day he ate it no problem...and he hardly gets any grain...just enough to eat the supplement actually. I think this is a great value and will keep him on it as I am pleased with how it has helped him.

    Rated 5 out of 5 by from I'm a believer I bought this product to provide extra support for my mare while she was on antibiotics. Previously when she had been on antibiotics she had issues with loose stool. This problem is no more thanks to SmartDigest! Within days I noticed a huge improvement, and she remained healthy with no issues throughout the course of her antibiotic treatment. I like it so much that I decided to keep her on it full time. I purchased the powder and she ate it right up.

    Rated 4 out of 5 by from Recomended I am glad I am giving my horse supplements, it is so easy and they hardly ever not work. My horse has issues with loose stool, and it is helping, but still needs some more time, since I haven't been using the product for a very long time. But I am pleased so far.
    Date published: 2016-12-14
    Rated 5 out of 5 by from Excellent product, super affordable. I bought this for my hard keeper to see if it would work, it immediately made a difference for him. And even better, I bought two big buckets of it during a 20% off sale, so it's only costing me roughly .50 cents a day!

    Rated 5 out of 5 by from smart digest powder I started this product after my donkey, was ill and had to be on antibiotics and steroids for extended periods of time.

    Rated 5 out of 5 by from I have had my two light duty horses on SmartDigest for 2 months and they seem much more comfortable. I have my performance horse on SmartDigest Ultra. He has been on 3yrs and with all the hauling and stress he has stayed very comfortable.

    Rated 5 out of 5 by from Really helps I originally bought this for my horses before the grass came in since they go several hours in between hay/grain. Once the grass started coming in I stop giving it until my senior horse was put on medicine for Cushings Disease. One of the side effects that were effecting him was loose stool and his was VERY loose. I found my self having to hose or rinse his backend down every day and I know it didn't make him feel very good. I starting giving this in his grain before I give him his medicine and we've had GREAT improvement on the stool side.
    Date published: 2016-07-07
    Rated 5 out of 5 by from seems to be working! I have tried 3 other SmartPak suppliments on Lacey, with no success. The SmartDigest seems to be making her less fussy and less cranky. So I'm keeping on it!
