ULZERless® Fresh Packs


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.
