ULZERless® Pellets

- %

Formula 707 ULZERless® provides natural support for the stomach lining to help maintain a healthy gastric system and support normal digestive function. Every hour, the parietal cells lining a horse’s stomach secrete more than six cups of concentrated acid. When horses can’t graze at will — and many horses can’t — the acid production in their stomach doesn’t stop.

Particularly for horses in high-stress training and performance situations, high-energy feed is quickly consumed and quickly digested, which means that, long after the stomach has emptied, the acid continues to flow. This can lead to ulcerations of the stomach lining and poor appetite — not to mention diminished performance and meager general condition. ULZERless is an effective combination of ingredients to aid digestion and ease the effects of acid on the stomach lining.

Just two ounces of Formula 707 ULZERless twice a day will maintain a healthy gastric system and help keep horses in top condition.

I have two of my horses on this

The taste seems great as my horses get very little grain and they can taste anything I add. Plus both my horses are going better than they ever have before. I will add that they get succeed as well to compliment Ulzerless and get the entire digestive track functioning well.

Been using for years - no colic, no problems. Highly recommend.

Works as it should. Price is reasonable. Always produce top products


Gave me by horse back! He is a homebred and has always been so willing and kind, then he started to shift and within a 6 month period if anyone got on and asked for more than a walk he'd get PISSED and threaten to buck them off, to buck me off! He was polite enough to threaten but a few times he did throw in the bucks and he was really unridable. Going from a nice dressage horse who could jump a 3ft course and do trail- to angry at any request given under saddle! I saw another horse get better on this product so tried it for mine and with in two weeks he was feeling good, now a few months in that's all like a bad dream. Poor guy was def in pain and I am so glad I found Ulzerless to help! Photos are recent after he started feeling better- he's still fat from being out of work for over a year- but he's happy.


I have two horses on this continuously and you can tell if they are not! Outstanding product that works!

Been feeding for years and my horses have never had gastrointestinal problems.

Rico J.

Haven't used it very long but it seems to be helping my big horse eat better after a tough train trip

Jen Lewis

So far so good. Just in the first month, but I notice less crankiness around feeding time.
