Rated 2 out of 5 by from Heard good things but horse won’t touch it Looks like a good product, but my horse wouldn’t eat it

Rated 5 out of 5 by from Ready to use Saves time and measuring. Perfect for my extreme working hours and seems to be helping my quarter horse that’s on vet required diet to aid her lameness issues.

Rated 5 out of 5 by from Significantly Reduced Cribbing & Improved Energy When my new OTTB arrived, I learned pretty quickly that she was a cribber. After a lot of research, I found that Neighlox has been shown to soothe cribber’s digestion by lowering acidity and thus reducing cribbing… within 24 hours of starting this, I noticed a huge improvement in my mare. Not only has her cribbing been significantly reduced, but her personality “opened up” as well. Her eyes are less dull and she has more energy and curiosity about the world. Can’t recommend Neighlox enough!

Rated 5 out of 5 by from A MUST HAVE i bought this a month ago, it IS a MUST have for my guy

Rated 5 out of 5 by from Worked great! Both of my mares get a very upset stomache with all the fresh grass in the spring. This year I started them on Neighlox Advanced and it made a huge difference. They were able to stay out longer and didn't have a upset stomache. My competition horse also became less cinchy!

Rated 4 out of 5 by from Easy to feed I bought this about a month ago and so far it seems my horse looks a little more comfortable.

Rated 5 out of 5 by from Neighlox works immediately I have used this product for over 10 years...within 24 hours of giving my mare neighlox instant relief and very noticeable with the appearance off my mare who has bleeding ulcers from race track I have even had people who know nothing about horses notice her attitude ability to barrel race and her appearance say what an improvement they saw in her ..I highly recommend this product and would not change to another product because this neighlox works so well I won't trust anything else.

Rated 5 out of 5 by from Great product. I use this in addition to omeprazole and the combination has worked great for my horse.

Rated 1 out of 5 by from Did absolutely nothing We had a horse that scoped positive for ulcers and completed the full course of gastrogard. He was also placed on Neigh-Lox Advanced to help speed the process, and then kept on it as a preventative. 2 months later we re-scoped and the ulcers are actually worse. I just removed them from our smart pak, I can't justify this crazy price for a product that didn't work.

Rated 5 out of 5 by from Great Product! I took on the responsibility of a rehab show horse with ulcers. This product has helped him immensely and he is healing quickly and on the road to recovery.
