Best Feed For Horses With Ulcers: to Support Healthy Digestion

Top picks: low-starch, high-fiber feeds with added gut buffers, alfalfa, and oil for safe calories.

You spot the classic signs. Your horse pins ears at girth time. He goes off grain and drops weight. He seems grumpy, even at rest. Ulcers are common, but you can help with the right diet. The best feed for horses with ulcers puts forage first, keeps starch low, and adds gentle fat for calories. Good products also support the gut with buffers, prebiotics, and minerals. I dug into what works and tested top choices. Here’s what I learned and what I recommend.

Triple Crown Senior Feed, High Fat & Fiber

This beet pulp–based senior feed has a gentle, forage-first formula. It offers high fiber and added fat for safe calories without a starch spike. Horses that struggle with weight or sensitivity tend to accept it well. It can be fed as a complete feed when hay intake is limited.

For ulcer-prone horses, its low non-structural carbohydrate (NSC) approach supports steady digestion. You also get gut-friendly extras like prebiotic and probiotic support in the brand’s EquiMix package. The pellets soak fast, which helps seniors with chewing issues and reduces choke risk. It is a popular base when you want the best feed for horses with ulcers in daily use.

Pros:

• Beet pulp and fiber-forward formula aids steady digestion
• Lower starch and sugar than many traditional sweet feeds
• Added fat for cool, safe calories and weight gain
• Prebiotics and probiotics support hindgut balance
• Soaks quickly for seniors with dental challenges
• Can act as a complete feed if hay is limited
• Consistent texture and good palatability in picky eaters
• Backed by a well-regarded equine nutrition program

Cons:

• Heavier horses may still need extra fat top-dressed
• Availability can vary by region and retailer
• Price per bag sits above basic performance feeds

My Recommendation

If you need a steady, low-NSC base that fits most ulcer-prone horses, start here. I reach for this when a horse drops weight or turns away from sweet feeds. The fiber and fat blend helps maintain topline without the heat or acid load you see with grain-heavy diets. It is also easy to customize with alfalfa pellets or oil if you need more calories.

In my barn, this has been the best feed for horses with ulcers that still need muscle and shine. I like it for seniors, hard keepers, and horses returning to work after treatment. Pair it with free-choice hay, salt, and vet-directed care for true results. Add small, frequent meals and you create a calm, consistent digestive routine.

Best for	Why
Seniors with dental issues	Soaks fast; can be a complete feed with balanced fiber
Ulcer-prone hard keepers	Low starch with added fat for safe weight gain
Picky eaters	Gentle taste and texture; good acceptance in trials

MagnaGard Gastric Support, 20 lb

MagnaGard is a powdered gastric support supplement built around key minerals. It is designed to buffer excess stomach acid and promote calm. Many riders note better focus under saddle and cleaner feed tubs. It works as a top-dress on any base feed or forage ration.

In ulcer management, the right supplement can help maintain comfort between meals. Ingredients like magnesium and calcium carbonate are common in buffers used for gastric support. This is not a drug and does not replace omeprazole therapy. But as part of a daily plan, it can support the best feed for horses with ulcers and improve day-to-day stability.

Pros:

• Mineral-based buffering supports stomach comfort
• Magnesium inclusion may aid focus and calm behavior
• Powder form mixes well with pellets or mash
• 20 lb bucket offers strong value for barns
• Simple top-dress makes dosing easy in busy routines
• Pairs well with low-NSC, high-fiber feeds
• Useful for travel days and show stress
• Palatable enough for picky eaters in most barns

Cons:

• Not a treatment for active ulcers; needs vet care alongside
• Some horses dislike powders without a damp mash
• Results can vary with workload and forage quality

My Recommendation

Use MagnaGard when you want a simple, daily buffer that plays well with any ration. I like it for horses in moderate work that show mild girthiness or mood dips. It helps smooth the edges during training blocks, travel, or turnout changes. The bucket size is barn-friendly and easy to scoop on the go.

I often pair this with the best feed for horses with ulcers, like a low-starch senior pellet and alfalfa. The goal is steady acid control and a calm mind. If your horse is on omeprazole, ask your vet when to add this to support maintenance. As of 2026, I still see mineral buffers as a useful layer in a full ulcer plan.

Best for	Why
Daily gastric maintenance	Buffers acid and supports comfort between meals
Horses in training	Mineral support may aid focus and reduce tension
Travel and show stress	Easy top-dress during stressful schedules

Triple Crown Senior Gold Feed, 50 lb

Senior Gold is a premium, textured version that targets weight gain and shine. It blends fiber sources with higher fat from oil and rice bran. Many horses eat it with gusto, even after turning away from bland rations. The texture helps mask top-dressed meds or supplements.

This formula includes the brand’s EquiMix package for digestive and immune support. The fat-forward energy helps you add calories without pushing starch too high. For ulcer-prone seniors or performance horses, this can be a smart upgrade. It is often my go-to when I need the best feed for horses with ulcers that must also fill out fast.

Pros:

• Higher fat for safe, cool calories and faster bloom
• Textured formula tends to boost appetite
• Includes prebiotics, probiotics, and essential micronutrients
• Supports topline and coat in hard keepers
• Pairs well with alfalfa and oil for added gain
• Suitable for mature and performance horses
• Helps disguise powders and pellets when needed
• Backed by a strong senior nutrition program

Cons:

• Texture can be a concern for choke-prone horses without soaking
• Higher fat can feel rich to very easy keepers
• Premium pricing versus basic senior feeds

My Recommendation

Choose Senior Gold when weight gain and appetite are top of mind. I like it for rescues, thin seniors, and horses in steady work that lost bloom. The fat helps without the mood swings of high-starch mixes. If your horse needs more, add 2–4 ounces of oil and a flake of alfalfa.

For many barns, this becomes the best feed for horses with ulcers that also have high calorie needs. Soak it if your horse bolts feed or has dental limits. Keep meals small and frequent, and always lead with hay. This keeps acid in check and makes every bite count toward comfort and condition.

Best for	Why
Underweight seniors	High fat and fiber add safe calories and bloom
Picky eaters	Textured formula tends to increase intake
Performance horses	Cool energy supports work without starch spikes

SBS Starting Gate Granules, 5 Gallon

Starting Gate Granules is a large-format gastric support supplement. It aims to relieve discomfort linked to stomach acid while also feeding hoof quality. The granular form blends into feed better than some powders. Barns with many horses will like the 5-gallon size for value and less frequent reordering.

This product is often used as part of an ulcer management routine. It can stand beside low-NSC feeds, alfalfa, and vet-directed therapy. The formula includes minerals and supportive nutrients for the stomach and hoof. For big barns seeking the best feed for horses with ulcers and a hoof boost, this is a strong all-in-one add-on.

Pros:

• Granules mix cleanly with pelleted or textured feeds
• Large 5-gallon tub suits multi-horse programs
• Targets gastric comfort with mineral support
• Includes nutrients often used for hoof quality
• Useful during training, shipping, and turnout shifts
• Pairs well with senior, low-NSC, and complete feeds
• Easy scoop-and-serve format in daily chores
• Commonly accepted even by selective eaters

Cons:

• Not a replacement for veterinary diagnosis or ulcer treatment
• Granules can settle; stir in a damp mash for best results
• Upfront tub cost is higher than small containers

My Recommendation

Pick this if you manage several ulcer-prone horses and want one solution that fits most. I like how it blends and how it supports both gut comfort and hoof health. Those are common pain points in real barns. Put it on top of a forage-first plan and a low-starch base feed for the best outcome.

In many cases, this creates the best feed for horses with ulcers as a system, not a single bag. Think hay nets, alfalfa, slow, small meals, and this granule on top. Confirm dosing with your vet if your horse is on other supplements. Consistency, not complexity, wins with gastric care in 2026 and beyond.

Best for	Why
Multi-horse barns	Large tub, easy dosing, and broad palatability
Ulcer-prone horses needing hoof support	Stomach and hoof nutrients in one daily add-on
Travel and show schedules	Simple routine that fits any base feed

SBS Starting Gate Granules, 1.1 Gallon

This is the smaller, more budget-friendly tub of the same granules. It suits one-horse owners or anyone testing a product before a bigger buy. You get the same gastric comfort approach and the same hoof-focused nutrients. The granular texture is easy to blend into a damp mash or soaked pellets.

It helps round out a low-NSC ration for sensitive horses. Use it as daily support or during stress windows, like clinics or weather swings. It does not replace vet care or prescribed treatments. But it partners well with the best feed for horses with ulcers in a simple, repeatable routine.

Pros:

• Smaller tub lowers upfront cost for single-horse owners
• Granules blend better than chalky powders
• Supports stomach comfort and hoof condition
• Easy to feed with soaked pellets or mash
• Consistent, repeatable dosing for daily use
• Good trial size before committing to a 5-gallon tub
• Pairs with any low-NSC feed program
• Helps during travel, training, and turnout changes

Cons:

• Less value per ounce than the 5-gallon size
• Granules may settle in dry feeds; dampen for best mix
• Not a cure for active ulcers; needs vet guidance

My Recommendation

Try this size if you are new to gastric supplements or manage one horse. It is a safe way to see if your horse eats the granules and shows comfort gains. I would add it to a forage-first plan and a low-starch senior pellet. Keep meals small and steady through the day.

This can help you build the best feed for horses with ulcers without blowing your budget. When you see steady progress, you can scale to the larger tub. Note changes in appetite, girthiness, and under-saddle focus. Track weight and coat to confirm that your plan is working.

Best for	Why
Single-horse owners	Affordable way to start gastric support
Picky eaters	Granules blend well in damp feeds
Trial runs	Test palatability and response before buying big
