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.

Harnessing nature's best

Licorice root is renowned for its soothing properties, helping to protect the stomach lining and reduce irritation. Grape seed extract is a potent antioxidant that supports overall health and helps combat oxidative stress. Marshmallow root provides a protective layer in the digestive tract, reducing discomfort. L-glutamine is essential for maintaining the integrity of the gut lining and supporting immune function. L-threonine aids in maintaining proper protein balance, crucial for muscle and tissue repair. Zinc is an important mineral for overall health, aiding in immune support and enzyme function. Together, these ingredients offer a comprehensive, natural approach to supporting your horse’s stomach health.

Why use a gastric support supplement?

1. Reduce digestive discomfort

Gastric support supplements help soothe and protect the stomach lining, reducing irritation and discomfort caused by stomach acid.

2. Promotes better behavior

By alleviating stomach discomfort, these supplements can lead to calmer, more consistent behavior in horses, reducing stress-related issues.

3. Long-term use okay

Unlike other means of supporting gastric health that may involve medication, consistent use of a supplement can help support overall health without negative side effects from long term use.

4. Supports healthy appetite 

Horses that struggle with appetite may be suffering from gastric discomfort. Supporting a healthy stomach can help horses eat the amounts they should be.

100% worth it

I put my retired 26 year old on this when he was showing signs of ulcers. After doing several omeprazole treatments, I started him on this. He’s been on it for maybe a year or more now and he’s no longer grumpy or ornery when you touch him on his side or belly (or just mess with him at all), he doesn’t show symptoms after he’s done eating, and overall he just seems more comfortable. I make sure to never run out of this so he can continue to live out his days without the pain of ulcers.


Love this product and have been using it for about 3 years now. My competition horses do great on it.

best fly control for the money

I use this every year after trying several others, the best by far.

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.

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!
