Product Overview

Promotes a normal gastric environment

In nature, horses graze and secrete saliva constantly, which buffers the stomach from gastric acid. When horses are stalled, this natural buffering mechanism is disrupted, and acid indigestion often results. Neigh-Lox® is designed to support normal stomach function by maintaining healthy acid levels and coating sensitive tissues. The ingredients in Neigh-Lox are long acting. The manufacturer recommends a SmartPak dosage of 1-2 scoops (2-4 oz) both AM and PM.
  • Provides coating agents that help safeguard the stomach
  • Includes buffering ingredients to help maintain healthy gastric acid levels

Neigh-Lox® is rated 4.7 out of 5 by 113.
Rated 5 out of 5 by from It does exactly what i need it to do My ottb had ulcers and this product helps keep them at bay. She also is keeping weight on really well.
Date published: 2016-07-30
Rated 3 out of 5 by from Packaged Well, releasable lid Not pre portioned at all, which would have been nice. Also, my horse HATES this. It looks like chalky tums but in pellet form - but my mare mostly finds her way around eating it. Does better when dampened with aloe juice or even just water but then if not cleaned up it turns to CONCRETE in the bottom of the bucket. I had to use my hoof pick and scrape and bang it out after soaking it in warm water.

Rated 5 out of 5 by from My horse loves NeighLox pellets! He looks forward to this and loves it. I have no idea why, as to me it tastes like chalk, but what do I know? Maybe it makes him feel good. :-)

Rated 5 out of 5 by from Love! I have a horse that was previously treated for ulcers and the neighlox works great for his digestive maintenance!

Rated 4 out of 5 by from Neigh-lox Saw a difference in my horse. No more weaving at the gate when I arrive at the barn
Date published: 2015-05-21
Rated 5 out of 5 by from It WORKS for ulcers! My horse developed ulcers from being shown at a young age and continued to get a worse attitude and hair coat. He didn't even want you to brush him and he was not interested in humans anymore. After 3 weeks on Neigh-Lox, after my trainer recommended it to me, my horse is more personable and has a shiny coat for the first time in years. I feed 2 scoops in morning and 2 scoops at night because I know he had really bad ulcers. It is the most affordable ulcer treatment I have found and I can continue to keep him on it. He even eats it all alone without any other grain.

Rated 5 out of 5 by from Worked well I moved my horse to a small boarding barn for the winter. He was a little touchy during grooming in the flank area. I was a bit worried if he was stressed by the move upsetting his Gi tract. Doing a scoop and 1/2 twice a day. All his symptoms went away.

Rated 5 out of 5 by from Neigh Lox I recently purchased a horse that was overall grumpy at feeding time, though he was in good health when I purchased him. It was apparent after observation, that he was prone to stomach distress at feeding time. He has now been on Smart Pak Neighlox twice daily with dietary changes as well and is a different horse! Very pleased!

Rated 3 out of 5 by from I bought this and our horse wouldn't eat it. We called recently and changed the supplement.
Date published: 2015-02-13
Rated 3 out of 5 by from Easy to measure, Easy to store The product is great and does exactly as the description. The item I purchased came in a large bucket easy for storing. The pellets are small so it would be easy for any horse to eat. The product is not flavored and unfortunately I had to return the product because my horse refused to eat it. SmartPak has fantastic customer service and worked with me during the returning process.
Date published: 2015-01-23
Rated 5 out of 5 by from Horse eats all his food now! My horse was always a slow eater (took hours to finish his food) and left much of his food untouched when we went to horse shows. Once I put him on Neighlox he finished all his food both at home and at shows.

Rated 5 out of 5 by from Great product My vet recommended I use this product. I have been very happy with the results and I have no problem with her eating this.
Date published: 2014-04-02
Rated 4 out of 5 by from Not my favorite but... I think this is a good supplement for horses having gastric problems, but I prefer SmartGut. This would be my second choice though because I have seen it help horses, but I have seen SmartGut help them more.
Date published: 2014-03-23
Rated 5 out of 5 by from Great product and easy to use An excellent product. It is great for horses heading to shows or other new environments, as well as for daily use for any who are prone to nerves. We just use it on a horse that came into the barn as a weaver. He is weaving less. Can't guarantee that there is a connection, but the timing suggests that there is one. I no longer show, but if I did, I wade take Neigh-Lox with me.

Rated 5 out of 5 by from Great results! I have used Neigh-Lox for years on the advice of my veterinarian.  My older mare has a delicate digestive system and this product works great!!

Rated 2 out of 5 by from Not a fan This works but it's expensive and I like smartgut if your horse has gastric problems.
Date published: 2013-11-17
Rated 5 out of 5 by from Worth the Money I have tried other name brands and they simply don't work. I have been using this product for a few months after the NeighLox Advanced and it is continuing to keep my mare comfortable. She is a picky eater and there is not problems with this supplement!!!
Date published: 2013-09-19
Rated 5 out of 5 by from My horse neighs for this After completing an expensive course of ulcergard and a first time move to a new barn coming up, I started my horse on this product to help protect and prevent ulcers from the stress of the move. I have him also on the SmartDigest, but this product seemed to cover what the SmartDigets does not. I was originally planning on just using for a couple of months, but my vet recommended he stay on this product. My horse likes the taste and always gobbles it up! After a month at the new barn he has no signs of ulcers or discomfort.
Date published: 2013-06-12
Rated 4 out of 5 by from Neigh-Lox I ordered this product after being told by the chiropractic/accupuncture vet that my pony showed sensitivity in his digestive meridian and was at risk for colic. He has been suffering from a painful back injury and I just didn't want to take any chances on him having more trouble so I started him on Neigh-Lox. So far it has been going well and my pony has no problem eating the pellets and no colic!
Date published: 2013-04-10
Rated 5 out of 5 by from Great My OTTTB has had bad ulcers for about a year now. Since I cannot afford Gastroguard daily for my horse I surched for something I could afford. After hearing about many products and and trying many, I gave neighlox a try and have had success since day 10. I have also given him free choice of hay. I feed 2 scoops once a day
Date published: 2013-03-13
Rated 5 out of 5 by from great product This product has really helped one of our field hunters. He's not as nervous and is eating so much better, and finally putting on weight. It took about 2 weeks to see a difference. We had tried many other products, which he would not eat, but this is the best for the money. This horse is a hard keeper and a very picky eater, but has never refused the Neigh-lox.

Rated 5 out of 5 by from important part of program I use Neighlox at times of year when my ulcer-prone horse is under extra stress, for example, at regional championships or in fall when seasonal changes make his stomach sensitive. It's part of a bigger digestive management program by which I aim to support all parts of his gut, from stomach to colon. This includes Succeed, Chia seed, and when necessary, Ulcergard. Overall, I believe that the immediate acid neutalizing provided by the Neighlox helps him a lot, as can been seen by his reduced anxiety and happy eating. He finds it very tasty too!

Rated 5 out of 5 by from Less stomach aches Our mare always showed signs of slight to really bad colic, especially after rides or right after eating. The vet, after hearing all her symptoms, suggested this product. We've been using it for over 6 months and she is doing great. Now that she no longer has pains in her stomach, her disposition is back to the sweet mare she was when we got her.
Date published: 2012-08-15
Rated 5 out of 5 by from Really great at preventing ulcers My vet reccommended this for my mare after treating her for a gastric ulcer with Gastroguard. I was a little skeptical since she is such a picky eater (she won't eat her feed if I had to put crushed up pills mixed with dried molasses in it!) but Smartpak worked with me and sent me a few samples to try and see if she would eat it. My horse didn't even bat an eye at eating her grain with Neigh-lox! And it has worked great so far at preventing another ulcer from occurring.

Rated 3 out of 5 by from Good Product, But Didn't Work for My Guy When my OTTB was diagnosed with gastric ulcers, several people suggested this supplement to me (friends, vet, equine masseuse). All said they had seen improvements in horses after 2-4 weeks on the product. My horse was on it for two months and he only continued to get worse. I switched him to SmartGut and after about 2 weeks he was showing significant improvement. Three weeks on the SmartGut and he's almost back to normal. While Neigh-Lox didn't work for my horse, I would still recommend it for ulcers because of how well it worked for all the people who recommended it to me. But I'd probably suggest trying SmartGut first, because that's what ultimately worked for my horse.

Rated 4 out of 5 by from She eats it... ...but I'm not sure yet how "effective" it will be keeping her ulcers at bay. My mare was diagnosed with Gastric Ulcers on January 17th, and was immediately started on 1 tube daily of GastroGard for 28 days. I also started her on NeighLox as soon as I could get it shipped to me, which was only about two days thanks to SmartPak's excellent shipping! After 28 days we rescoped her, ulcers were shown as completely healed. We discontinued the GastroGard, adn she remained on NeighLox, alfalfa, and Triple Crown Senior. After a few days off the GastroGard, she started slowly losing her appetite again. I did not see that NeighLox kept her entirely comfortable, but they were pretty severe ulcers, so that my be a contributing factor. I put her on a preventative dose of UlcerGard paste for a few days and her appetite came back. I'm going to keep her on NeighLox at the recommendation of my vet. I'm not sure though, how effective it is at this point with my mare. I will say that I did the cost comparison of purchasing this via SmartPaks and by the bucket, and it is MUCH cheaper in SmartPaks!
