I have been using this product for years and it’s helped manage and prevent the recurrence of my mares ulcers.
Covers all basis, having similar ingredients to all those super expensive veterinary sold supplements!
It’s palatable according my mare (and she would tell me if she disapproved!) and does the job.
Highly recommended

Looking at ingredients it appears good value for money against other brands. Although its hard to judge when companies don't put the amount of each active ingredient so don't always know if one brand has larger quantity of active ingredient.
Aa it's a powder and you feed a couple large scoops per feed I tend to syringe it as she dosnt have hard feed due to her weight and the balancer gets lost in all the powder.
I havnt used it long enough to comment on if I think it helps

Great service and great product!
My 27year old mare has a very sensitive stomach and FFW but since using ultimate gastro ease I feel like it’s far more under control. We are on our 3rd month now and won’t be going back!

Just started feeding so have no real feedback other than it is taking a bit of time to introduce the full dose.

I’ve recommended this product to many of my clients. It’s very good in helping to minimise acidity in the gut and thus help with the prevention of ulcers. There is a noticeable difference in the horses when they’re not on it compared to when they are.

My horse has been recently treated for gastric ulcers. I read through the ingredients of several supplements and settled on ultimate gastric-ease. My horse has been less girthy and looks well since starting on this supplement.

We have a busy event season ahead - I hope the combination of his high fibre diet and ultimate gastric-ease helps prevent his ulcers from reoccurring.

Nutrition Information

Ensuring digestive comfort is important to allow our horses to thrive and perform to the best of their ability. Ultimate Gastro-Ease® is a unique blend of ingredients that supports comfortable and efficient digestion by providing complete support from the stomach to the hindgut.  

The mineral salts Calcium carbonate, Dicalcium phosphate, Magnesium hydroxide, and Magnesium carbonate, contribute to maintaining a healthy gastric environment and help support the mucosal lining of the stomach and small intestine.  

Lecithin is highly hydrophobic (water hating), while Pectin forms a gel-like substance that binds to bile acids when exposed to an acidic environment. When combined, Lecithin and Pectin support the natural protective mucosa of the stomach, which is known to become irritated by high-concentrate diets, medications, and stress.

Support for the sensitive microbial population in the hindgut is provided by the unique combination of pre-, pro- and postbiotics in Ultimate Gastro-Ease®:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Prebiotics:

The prebiotics (Fructooligosaccharide (FOS) and Mannan oligosaccharide (MOS)) provide food sources for beneficial bacteria that are responsible for fermenting fibrous foodstuffs the horse eats.  

 

Probiotics:

The probiotic YeaSacc® provides the horse with a supply of live yeast (Saccharomyces cerevisiae) which is an important component of the microbial population, and which stimulates the activity of bacteria within the hindgut, optimising fibre fermentation. This probiotic also maintains activity of bacteria that break down lactate which helps to support the hindgut.  

 

Postbiotics :

Postbiotics are non-living microorganisms and their byproducts, that can support your horse’s gut health. In Ultimate Gastro-Ease®, the postbiotics contain beneficial cell components and metabolites. These work to promote a healthy balance of bacteria in the horse’s gut, supporting overall digestive health.

Postbiotics have been shown to increase volatile fatty acid production in horses, which enhances fibre fermentation, particularly for high-fibre forages. This makes Ultimate Gastro-Ease® particularly beneficial for horses and ponies fed low calorie, high fibre diets and for metabolic or weight management reasons. 

Bacteria species within the hindgut are also more consistent in horses fed the postbiotic compared to those fed a control diet, making it beneficial for keeping the hindgut stable and maintaining digestive comfort. 

 

Further supporting immunity in Ultimate Gastro-Ease® are Kaolin and specialised beta glucans which bind to pathogens, helping to keep the gut healthy. The amino acid Glutamine also provides an energy source to immune cells ensuring optimal function. 

With an aromatic and settling mint aroma, Ultimate Gastro-Ease® provides a highly palatable unique combination of ingredients suitable for all horses and ponies with additional digestive, gastric and hindgut needs.

Feeding Guide

Up to 250kg 1 ½ scoops 
250kg - 400kg 2 ½ scoops

Ultimate Gastro-Ease® should be added immediately prior to feeding, keeping the supplement as dry as possible, otherwise effectiveness may be lost.

Avoid feeding large concentrate meals (pellets, mixes and grains). Instead feed little and often throughout the day, especially concentrate feeds. Always feed at least 1.5% of your horse's body weight per day as fibrous forage (for a 500kg horse feed at least 7.5kg of fibre per day). Horses showing signs of excess acid should have continuous access to forage.


Ultimate Gastro-Ease® is a complementary feeding stuff for equine animals. Feed supplements should be fed according to body weight. Introduce to the horse’s diet gradually, splitting between feeds (when applicable). Feedmark uses nothing in the formulation of this product that contravenes competition rules.

Shake periodically to avoid settling.
