The Problem Isn't Stomach Acid.

Your horse's stomach was designed to be acidic. In fact, horses produce stomach acid continuously, 24 hours a day, because they evolved to digest fibre almost constantly.

So why do so many gastric support products focus solely on reducing acid for horse stomach health?

When active gastric ulcers are present, veterinary-prescribed medications such as GastroGard® and sucralfate can play an essential role in treatment. Under veterinary supervision, reducing acid exposure with targeted medication helps create an environment where ulcers can heal.

But once that process is complete, in order to maintain a healthy stomach, does it make sense to spend the rest of your horse's life trying to suppress something their digestive system naturally depends on?

At Equell, we believe long-term digestive support should focus on helping the stomach do what it was designed to do, whilst supporting the natural protective mechanisms that help keep it comfortable.

Why Horses Need Stomach Acid

Acid:
✓ Breaks down feed
✓ Supports digestion
✓ Is a natural part of equine physiology

Stomach acid is not a flaw in your horse's digestive system, it is a fundamental part of it.

Without adequate acidity, digestion becomes less efficient. Fibre, protein and nutrients rely on the stomach beginning the digestive process properly before feed moves further down the digestive tract. Reducing acid suppression means increased pressure on the hindgut as partially undigested food moves there.

This is why acid suppression should always be viewed in context.

When ulcers are present, reducing acid under veterinary supervision using prescribed medications helps protect damaged tissue whilst healing occurs but healthy digestion depends on the stomach remaining acidic.

The long term goal for maintaining a healthy stomach isn't eliminating acid, the goal is supporting the horse's ability to cope with it.

Modern Horses Face Challenges Nature Never Intended

Travel, competition schedules, routine changes, periods without forage and intensive exercise can all place pressure on the stomach's natural protective mechanisms.

Over time, the delicate mucosal lining can become vulnerable to acid splash and that's why supporting the stomach's natural defences matters rather than simply reducing the acid itself.

Support The Mucosa. Support The Horse.

The stomach's first line of defence isn't reducing acid, it is the protective barrier that separates stomach acid from the stomach wall itself. This delicate mucosal layer helps defend against the natural acidity required for digestion.

Ulceraid is designed to support this protective environment, using meaningful levels of carefully selected ingredients including our lecithin and pectin matrix which combines in the stomach to form a gel like substance to buffer your horse's natural defence mechanism.

No fairy dust.

No empty marketing claims.

Meaningful daily support.

Ingredients Only Matter If There's Enough Of Them.

One of the biggest problems in the supplement industry is what we affectionately like to call "fairy dusting".

A long ingredient list looks impressive, but if those ingredients are present at tiny levels, what are they really contributing to your horse's health?

At Equell we publish our active ingredient levels openly because we believe owners deserve to know exactly what their horse receives every day

The Gel-Forming Matrix

Lecithin and pectin have been included at meaningful levels for a reason.

When hydrated within the stomach they combine to form a gel-like substance that helps support the stomach's natural protective mechanisms.

Rather than attempting to remove stomach acid, Ulceraid works alongside the horse's normal physiology, supporting comfort, mucosal integrity and the environment the stomach was designed to maintain. 

Why Glutamine & Arginine Matter

Gut Health Doesn't Stop At The Stomach

The stomach may receive most of the attention but the hindgut is where much of the magic happens!

Trillions of microbes help digest fibre, produce beneficial compounds and support digestive wellbeing, yet many gastric supplements completely ignore hindgut health, focusing instead on suppressing acid which may put extra strain on the hindgut when used longterm.

Ulceraid doesn't. We include a variety of prebiotic fibres and powerful natural antioxidants for optimal hindgut health.

Feed The Microbiome. Don't Just Add To It.

The supplement industry loves buzzwords.

• Probiotics.
• Postbiotics.
• Tribiotics.

But healthy microbial populations need feeding to really thrive. That's why Ulceraid includes:

✓ MOS

✓ Beta glucans

✓ Postbiotics

✓ Multiple prebiotic substrates

Rather than relying on a single chicory-derived prebiotic source or adding more bacteria (probiotics) to a potentially compromised gut environment that may not have sufficient prebiotics to sustain even it's existing colony.

A healthy microbiome begins with nourishment.

The Gut-Brain Connection

The digestive system and nervous system are constantly communicating.

This relationship (often referred to as the gut-brain axis) is one reason digestive comfort can influence overall wellbeing.

By supporting the digestive environment, many owners report horses feeling happier, more relaxed and more comfortable in their work.
