Natural Ulcer Support for Horses
Ulcers are common, often subtle, and closely tied to how horses are fed and managed. The right support starts with understanding the digestive system properly.
Equine ulcers are one of the most underdiagnosed — and often over-medicated — problems in horses. Some horses show obvious signs like poor appetite, weight loss, or resistance around the girth. Others just seem tense, irritable, picky with feed, or “not quite right.” Because those signs can overlap with training, management, and temperament issues, ulcers are easy to miss until they become a bigger problem.
The good news is that many ulcer-prone horses improve when their feeding routine and daily management are adjusted in a smarter way. That does not mean every horse can be handled with supplements alone, and severe cases still need proper veterinary attention. But it does mean owners do not have to sit and wait helplessly. There is a lot you can do early to support the stomach and gut.
This article covers common ulcer triggers, the signs owners should watch for, natural strategies that can help, and the Mad Barn products that make the most sense when building an ulcer-support plan.
Stress is a major factor in ulcer development. Improving your horse’s daily environment can help — see our guide on mental stimulation for horses.

What Causes Ulcers in Horses?
Ulcers rarely happen for just one reason. In most cases, they develop when the horse’s natural feeding pattern is disrupted or when stress increases faster than the digestive system can cope. Horses are designed to eat forage almost constantly, so anything that creates long empty periods in the stomach can increase ulcer risk.
Long gaps between meals
When horses go too long without forage, stomach acid has less material to buffer it. This is one of the most common feeding mistakes behind ulcer problems, especially in stalled horses or horses on tightly scheduled meal plans.
High-grain diets
Large grain meals can increase digestive stress and shift the feeding program away from the fiber-based approach horses are built for. Some horses tolerate this better than others, but in ulcer-prone horses it often works against stomach comfort.
Stress
Travel, training, changes in turnout, competition schedules, and even shifts in routine can all contribute to digestive stress. Some horses are especially sensitive and will show stomach-related signs quickly when their routine changes.
NSAIDs such as Bute
Non-steroidal anti-inflammatory drugs can be useful medications, but they can also add pressure to the digestive system when used heavily or repeatedly. That is why horses on these medications deserve extra care in their feeding and management routine.
Signs to Watch For
Ulcer signs are not always dramatic. In fact, many horses with gastric discomfort only show subtle behavior and feeding changes at first. That is part of why so many cases slip under the radar.
Girthiness
A horse that pins ears, tenses up, or becomes defensive when being girthed may be reacting to abdominal or stomach discomfort rather than just being “grumpy.”
Poor appetite or slow eating
Some ulcer-prone horses approach feed, nibble at it, and then walk away. Others eat more slowly than usual or seem less interested in meals they previously enjoyed.
Unexplained weight loss
If a horse is eating but not holding condition well, ulcers or digestive stress may be part of the picture. This is especially true if appetite or comfort seems inconsistent.
Grinding teeth or cribbing
These behaviors can be linked with discomfort. They are not exclusive to ulcers, but when they appear alongside feeding issues or irritability, they deserve attention.
Natural Strategies That Help Support Ulcer-Prone Horses
Free-choice forage
One of the simplest and most effective changes is making sure the horse has frequent access to forage. Hay nets can help slow intake and reduce long gaps between eating sessions, which is often a major win for stomach comfort.
Low-starch, high-fiber feeding
Ulcer-prone horses usually do better on fiber-first feeding programs rather than heavy starch or grain-focused diets. The goal is to support the horse’s natural digestive design instead of constantly challenging it.
Prebiotics and probiotics
These can help support a more stable gut environment, especially in horses under stress or horses with broader digestive sensitivity. While they are not a magic cure, they can be useful in a complete gut-support plan.
Tissue-soothing ingredients
Ingredients such as aloe, marshmallow root, and licorice are often used in natural digestive support strategies because they are chosen to help soothe irritated tissues and support comfort in the digestive tract.
Best Mad Barn Supplements for Ulcer Support
Mad Barn Visceral+
Best for: Horses with ulcer risk, gastric sensitivity, poor appetite, girthiness, stress-related digestive issues, or recurring signs of stomach discomfort.
Visceral+ is the strongest fit for this topic because it is designed specifically for horses with gastric health concerns. It makes sense for horses that seem stressy, ulcer-prone, or uncomfortable through the stomach and gut.
What makes it especially useful is that it is not limited to one narrow angle. It is built around broader gastric and hindgut support, which gives owners a more complete starting point when they are trying to support an ulcer-prone horse naturally.
Check PriceMad Barn W-3 Oil
Best for: Horses that need extra calories or help maintaining condition, but where high-starch grain feeding may worsen digestive stress.
W-3 Oil is a smart choice for horses that lose condition easily or need more energy in the diet without relying on grain-heavy meals. For ulcer-prone horses, this matters because owners often need a way to support body condition without simply feeding more starch.
What makes this useful is that it helps shift the feeding plan toward a safer calorie source. That can be especially valuable for performance horses, harder keepers, and horses whose condition suffers when their stomach is unhappy.
Check PriceMad Barn Optimum Digestive Health
Best for: Horses with broader digestive imbalance, unstable manure, stress-related gut issues, or owners wanting to support microbial balance alongside ulcer-focused feeding changes.
Optimum Digestive Health fits well when the horse’s problem seems bigger than the stomach alone. Some horses with ulcer tendencies also show signs of hindgut imbalance, feed sensitivity, or inconsistent manure, and that is where this kind of broader digestive formula can be useful.
What makes it a good addition is that it supports the gut environment more generally. If your horse’s digestive system feels unsettled overall, this can help create a better foundation for the rest of your management plan.

Feed forage first
If concentrates are fed, it usually makes sense to avoid giving them into an empty stomach. Starting with forage helps create a better digestive buffer.
Reduce unnecessary starch
Not every horse needs grain-heavy meals. In many ulcer-prone horses, reducing starch and leaning more on forage and safer calorie sources improves comfort.
Keep the routine predictable
Some horses are extremely sensitive to change. Consistent feeding times, steady turnout, and fewer abrupt management shifts can help lower digestive stress.
Support the whole gut, not just the stomach
Stomach comfort is important, but broader gut health matters too. Horses often do best when the feeding plan supports digestion as a whole.
What Owners Often Get Wrong
Waiting too long to support the horse
Owners sometimes wait for a full diagnosis before changing obviously risky feeding patterns. But simple steps like improving forage access and lowering starch can often be started earlier.
Trying to out-feed ulcers with grain
If the horse is losing condition, the instinct is often to add more concentrate. In ulcer-prone horses, that can backfire if it increases digestive stress instead of helping it.
Assuming every behavioral problem is training-related
Some horses labeled difficult or reactive are actually uncomfortable. Digestive discomfort is one of the more overlooked reasons behind changes in attitude.
Relying on one single fix
Ulcer support usually works best as a combination of feeding changes, better routine, stress reduction, and targeted supplementation.
Frequently Asked Questions
What are the first signs of ulcers in horses?
Common early signs include girthiness, poor appetite, slow eating, irritability, weight loss, teeth grinding, and changes in behavior.
Can horses with ulcers improve naturally?
Mild or early cases often benefit from better feeding management, more forage, lower starch intake, and targeted digestive support. More serious cases still need veterinary assessment.
Is grain bad for ulcer-prone horses?
Large grain meals can increase digestive stress in many ulcer-prone horses. A more fiber-based feeding plan is often a better fit.
What is the best supplement for horses prone to ulcers?
A product designed specifically for gastric and hindgut support, such as Visceral+, is usually the best starting point when ulcers or stomach sensitivity are the main concern.
Final Verdict
You do not have to wait for scopes or prescriptions before improving an obviously risky feeding routine. For many horses, better forage access, lower starch intake, and a more stomach-friendly management plan can make a big difference.
If you want the best all-around product for this topic, Mad Barn Visceral+ is the strongest fit. If the horse also needs more calories without pushing grain higher, Mad Barn W-3 Oil is a smart addition. And if you want broader gut support alongside ulcer prevention, Mad Barn Optimum Digestive Health rounds out the plan well.
A thoughtful feeding routine and targeted supplementation go a long way in helping manage and prevent ulcers in horses.
