    Rated 4 out of 5 by from Still Early Still to early to tell whether this product is really helping or not, but I bought the powder and when it's mixed in with her grain my horse doesn't seem to have any problem eating it. Also, it's not cheap!

    Rated 5 out of 5 by from Works for Rue U7 Gastric Aid works for my mare. To me, she was showing signs of gastric distress-when she heard the diesel truck backing up to hook up to the trailer, she would break out in a sweat just in front of her withers which was odd since she was standing in her stall-Having been on the quarter mile track as a 2 year old, I put 2 + 2 together and came up with a "ulcer" suspicion-I started her on the Smart Pak U7 Gastric Aid, and she has been on it since-she no longer shows signs of distress-and became a calm quieter horse-

    Rated 4 out of 5 by from U-7 Gastric Aid After several attempts to find a Gastric supplement that my horse would eat, U-7 Gastric Aid works and his symptoms are going away. I would recommend this supplement for your horse with ulcer/anxiety symptoms.

    Rated 5 out of 5 by from Unbelieveable Responce to this product! I brought in a horse as a prospect and about a month later he started getting all colicky and stressed out and then started cribbing! I was in shock.. the vet suggested I out him on a gastric product and holy geeze. He's back to normal, stopped cribbing and looks great! 5 Stars.. I can't beleive that one little scoop of this stopped all the systoms immedietaly. Thanls

    Rated 5 out of 5 by from Great for picky eaters! I started using this product at the recommendation of my trainer after my horse developed issues with ulcers after we moved barns and he had to be stalled for 12+ hours a day for most of the year. After I started using it, I saw some definite improvement with the girthiness & sensitivity he had developed. Now that it is summer, he lives out 24/7 and his issues have completely resolved, but I continue to keep him on this product. Why? He absolutely loves it! He is a picky eater and a hard keeper. I usually have problems getting him to eat enough grain- I've tried pureed carrots, molasses, oil, applesauce, bran mashes, beet pulp, you name it. He will eat it for a day and then won't touch it. But he will eat anything I put this on! Great product- we will be using this for a very long time!

    Rated 5 out of 5 by from Amazing!! I have had my Appendix Quarter Horse on this product for less than a month. He is gaining weight, better mood, seems to be more relaxed. It is amazing. He is a picky eater and he will lick this off the rubber tub. He has had no stomach issues. Also he is eating much better, like he enjoys it now! Thanks Finish Line for a wonderful product!

    Rated 5 out of 5 by from It works, but my horse doesn't like the taste My horse is prone to ulcers spring and fall. Since he has been on U7 I have not had to treat him for ulcers. It must be working, he is not showing any signs of ulcers and he has been on it for over a year. He does not really like the taste though-tends to eat around it and then clean it up over night. He liked the taste of Succeed better, but I think U7 works better for the money.
    Date published: 2011-05-21
    Rated 5 out of 5 by from I have a very picky gelding and he loves the liquid U7. He has been fighting ulcers for 2 years and I started him on this product and magnesium and he is almost back to his regular performance. He has been on it for less than a month. The first month is a little pricey, but after the initial "double" dose, the cost is comparitable to other products and the fact that he likes is well worth the cost.

    Rated 3 out of 5 by from Not what I expected... I purchased this for my retired gelding who is currently on bute 3 times a week. I wanted to add this to his feed to help with the issues with the bute. I loved the product and my gelding who is a very fussy eater. I just was expecting the gallon size container for the price. I would recommend this product but the size was disappointing.

    Rated 5 out of 5 by from Good choice for the stressed and in transitions! I use this on OTTBs and polo ponies regularly who are working hard and those who have a high potential for stress. We rarely have any stomach issues (never loose stools) and I definitely thinks it keeps them more comfortable. It is especially beneficial to those coming off the track to the farm and into work.

    Rated 5 out of 5 by from Excellent for Ulcer Prevention My TB is ulcer prone and I have treated him twice with GastroGuard for his ulcers. I tried several different preventative products in between treatments, this is the only one that has kept him ulcer free for a year now. He is a picky eater and has no problem eating this supplement.

    Rated 4 out of 5 by from U-7 U-7 I use daily, I was not happy with the smart pack purchase. I did not realize what it was I ordered. They show the big bucket size in the picture and that is what I was interested in. I use the liquid daily at dinner time and wanted to use the powder in the AM. I would not waste money on the "Smart Packs".
    Date published: 2010-07-01
    Rated 4 out of 5 by from I have not been using this for very long (just over 2 months maybe?) but it is starting to make a difference. Horse is hardly girthy at all anymore, and I am confident that this is from adding this to his diet, as he is very prone to ulcers.

    Rated 5 out of 5 by from Life Saver I gave this product to my horse after a long bout with colic. She had 2 hospital stays and still coliced every time I got her home. The vets were saying she might be better off if we put her down. I started her on U-7 and she never coliced again.

    Rated 5 out of 5 by from A life changer for my horse I bought an off the track 9 year old TB Gelding whom seemed to have never been turned out in his life. He along with other health inbalances had the worst appitite I have seen from any speices of animal. A 17 hh TB who couldn't care less about grain, barely liked hay and picky with treats even (he ignored all but anise or pepermint,which are both herbs that treat tummy upset). His manure was soupy and he was in a horrid mood undersaddle. Due to his history I guessed he had some bad ulcers (bute, racing, lack of turnout) . He was given U-7 powder for 18 months in smartpaks and it had a phenominal difference for him. He immediately displayed a better appitite and mood, and he kept getting better and better. After 18 months, we tried him with out it and viola'! He maintained his improvement and never needed it again (his was not shown, low stress life, lots of turnout) . U-7 went WAY BEYOND treating his tummy, IT CURED HIM! Highly palatable, great value (he ate the grain we bought) and no drugs. Aidan sends his thanks to Finish line, as he no longer lives in pain.

    Rated 5 out of 5 by from Wonderful product!! My horse has had ulcers for years, this product has significantly reduced her symptoms and her discomfort. I also love the smartpak packaging of the product because it doesn't freeze like the liquid version in the cold Buffalo winters and it mixes right into her grain!!!
    Date published: 2009-06-16
    Rated 4 out of 5 by from Can't Tell! I spoke directly with the good folks at Finish Line, and they were quite positive that U-7 would help to end my horse's cribbing addiction. well, the short story is, it didn't. But the longer version is that he is much quieter and calmer since he's been on it. For that reason, I continue to use it! I'm not sure it's the U-7 or not, but I'm not taking a chance! Very thick viscosity, so it can be hard to measure. I use an old Finish Line Fluid Action container, the type that you push the liquid up into the oz. measurer. It can get almost impossible as it grows empty. Since you feed it twice daily, it can be on the pricey side, but hey! If it works, it is worth it, right?
    Date published: 2009-04-07
    Rated 5 out of 5 by from No Worries Here! My wonderful gelding has never acted like a warrier, but he would lie down during feeding, kick out at grooming, and had one severe colic episode. I treated him for ulcers and put him on U-7 having read positive reviews. I am happy to report he has never given any evidence of tummy discomfort since! U-7 - I know I will never go without it.
    Date published: 2007-07-06
    Rated 5 out of 5 by from Helped with loose poop I bought a 6yo, unraced TB gelding and he had cow patty type poop....very flat and wet, no form or the classic "apples" horses are supposed to produce. I did a power pack worming, added aloe vera to his diet, tested his droppings for organisms that might cause it, nothing. I put him on a daily wormer...slightly better, but not good enough. Then I tried Finish Line U-7 Gastric formula because I liked the ingredients, and presto, he has normal droppings now. His poop used to be so wet he had thrush in 3 out of 4 feet in spite of mucking his stall 2x daily. Good stuff.
