Helps ensure a healthy GI tract

  • Provides saccharomyces cerevisiae, a yeast that supports fiber digestion
Research has shown that providing yeast stabilizes cecal and colon pH, helping to ensure a healthy gastro-intestinal tract. Yea-Sacc 1026 supports the digestion of fiber, providing more energy for performance and pleasure horses, as well as older horses. Improved digestion also enhances phosphorus and calcium availability for greater bone strength. Yea-Sacc 1026 stimulates milk production in lactating mares, and produces more nitrogen for higher milk quality – resulting in healthier foals.

    Yea-Sacc is rated 4.4 out of 5 by 33.
    Rated 5 out of 5 by from stopped loose bowels and belly ache Got a former barrel horse who did not respond to various attempts to stop his loose stools through diet and various supplements. A friend gave me this and it was the first thing to work. Within a week he was more regular and seemed to have less pain.

    Rated 5 out of 5 by from It works! I bought this after moving my late-teens tb with us to a new state. He started having occasional belly-aches. I put him on yea-sac and he has stayed comfortable since! Thank you!

    Rated 2 out of 5 by from Weird experience ... mare refused to eat it My mare loves Yea-Sacc, gobbles it up. So I thought I'd add it to her Smartpaks. But she refused to even try it. I took the pak home and compared the two products. They didn't look the same, or taste the same. No wonder she refused it. No idea if Smartpak just got a bad batch ... Yea-Sacc is a terrific product. I'm going back to giving her the product from other source even if I do have to bag my own portions for the barn.

    Rated 4 out of 5 by from Helped a little I have a senior horse with extreme diarrhea. He's gained weight and has been feeling better since being on this, but it did not cure his diarrhea. I am going to start him on Stomach Soother from another website, hopefully that will work.

    Rated 5 out of 5 by from Good Value I feel safe having my horse on this inexpensive supplement that has been shown in peer reviewed journals to help prevent certain types of colic.
    Date published: 2012-06-20
    Rated 4 out of 5 by from Just getting started I just started using Yea-Sacc it was recommended by my vet after a serious colic episode with my thoroughbred. He didn't like it on top but doesn't even notice it once mixed in and he's doing well, so far so good!
    Date published: 2012-05-01
    Rated 5 out of 5 by from Helpful Product I have a tiny mini who suffered a bout of colic and I decided to give this product a try. It seems to be working and I do think her overall health has improved since she has started Yea-Sacc. It's very cost effective too.
    Date published: 2012-04-21
    Rated 4 out of 5 by from Seems to work I tried this supplement for my mare when she experienced gas colic several times last fall after being turned out on fresh grass. I think this helped keep everything in balance the next few times she went out but I can't say for sure as we also were treating her for ulcers at the same time as using this product. I have since switched her to SmartCombo (contains SmartDigest) and U-Gard because I needed some of the other supplements and the Combo was a better price.

    Rated 5 out of 5 by from Really Helped My Horse My horse tends to have gas and be a bit uncomfortable with his digestive system - not really colic but discomfort. Tried lots of other digestion supplements & probiotics but this was the final key to making him comfortable. I don't understand why this very small amount of an inexpensive supplement worked - but it worked for me. Give it a try.
    Date published: 2011-08-04
    Rated 4 out of 5 by from Vet Recommended My horse had to have colic surgery and I wanted something to help with digestion. My vet said that the only proven supplement is Yea Sacc and she uses it at the clinic. So far, so good. I'm hoping it helps keep him healthy.

    Rated 5 out of 5 by from Love It I have a 6 yr old QH Mare that started getting tummy aches over a year ago.. after spending a lot of money on veterinary farm calls i decided to do some research.. the vets told me some horses just do this their entire lives... well after reading the reviews on this product i decided to try it...for the price i figured i wasn't losing much. Well let me tell you.. she has not had a colic episode since being on this product. I am very happy with it and recommend it to anyone who's horse gets frequent tummy aches ..

    Rated 5 out of 5 by from Works for loose stools I ordered the yea-sacc on the advice of an equine nutritionist who recommended it for loose stools in my horses. It works! I gave it 4 stars for palatability because they turned their noses up initially so I had to add some sweet feed to get them past the taste.
    Date published: 2010-12-03
    Rated 5 out of 5 by from Hasn't coliced since starting My 10 year old APHA gelding has not even had a small bout of colic!! I would definitely recommend this to anyone who has a horse that colics!! If you want to do more research on Yea Sacc, check out the Alltech site. It gives more information.
    Date published: 2010-07-20
    Rated 5 out of 5 by from FINALLY - Something that Works I have a large Danish WB gelding that has had gas colic problems for years. I have tried probiotics, ulcer meds, different feeds, all kinds of supplements. Yea-Sacc is the only thing that has given consistent good results. IT WORKS & IS NOT EXPENSIVE!!!
    Date published: 2010-07-10
    Rated 5 out of 5 by from Actually works! I have a very large OTTB 18.1 that for over a year we have tried so many products some recommended by our vets to no avail in stopping his loose stools. This has been the only product that actually works! It took about 2 weeks to kick in...and what a difference not only normal manure but putting weight back on he is absorbing all of his nutrients now. It is very rare for me to give a review of a product, but this one is deserving.

    Rated 5 out of 5 by from Big improvement for older Horse We have an older horse (who is now 23) and a few years back he was having alot of episodes of Mild Gas Colic. We were very careful to limit his grass in the spring and be consistant with his grain. I read about this product and decided to give it a try. After he was on it for several months we stopped having the problem.
    Date published: 2009-05-14
    Rated 5 out of 5 by from My life saving supplement! Ever since my gelding had a bout of colic in 2004, he has been on a steady ration of Yea-Sacc. As a formulated digestive aid, giving it ensures that every particle of food is absorbed and utilitzed to its maximum. This of course, aids in making sure his diet remains consistent and thus prevents colic. I wouldn't go a day without this supplement - it is vital to my horse.
    Date published: 2009-05-04
    Rated 4 out of 5 by from Yea Sacc This product was recommended to me by my vet.. My 23 year old gelding was getting gas colic at least once a month. Since using Yea Sacc the problem has subsided and I see a great difference in his overall well being. I believe this product has helped his digestive system alot in the last year.
    Date published: 2009-05-04
    Rated 5 out of 5 by from this stuff works! I've have a horse that has had chronic diarhea for YEARS - this is the ONLY product I have used that has actually worked to "dry him up" ! LOVE IT!!!!
    Date published: 2009-04-29
    Rated 5 out of 5 by from Love this Product I put my 9 year old TB gelding on this supplement after he had recovered from colic surgery - it has been over 2 years and his digestive system is doing great!! I highly recommend this supplement as a little insurance policy again "upset stomachs". Colic is caused for many reasons but Yea Saac definately helps with digestive disorders - it can only help!
    Date published: 2009-04-10
    Rated 5 out of 5 by from My ponies will not go without I started using yea sac over a year ago. Our weather has been up and down with huge swings in temperatures, both in the summer and winter. Since I have fed this suppliment my ponies have never had a colic or any type of intestinal disorder. Where my friends have had many. ( they now use yea sac) They all appear more healthy and I don t have to worry as much about drastic weather swings.
    Date published: 2009-02-16
    Rated 5 out of 5 by from A must for every barn. We bought a large Warmblood jumper who had a history of persistent mild colic whenever he traveled, showed, or experienced any stress. The farm purchased this product on a whim, mainly due to its pleasant aroma! To our surprise, this gelding hasn't had a single episode of colic since he was purchased over a year ago. He can go back to being a normal horse again instead of being treated like a fragile, high maintenance animal. It's easy to feed, very palatable and definitely works. We're trying it this year on the farm's broodmares.
