Two of my horses have previously suffered from free faecal water syndrome when on large amounts of haylage in the winter. I started them on Ultimate Gastro Ease and no longer have to deal with constantly cleaning tails and hind legs of runny poo water.

Love this product

Excellent value for money and so eco friendly that you are able to buy plastic  free refill bags.

No issues with palatability and my horse is quite fussy. This has kept his gut really happy and healthy since ulcer treatment

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

 
Weight of Horse/Pony           Amount per day
Up to 250kg 1 ½ scoops 
250kg - 400kg 2 ½ scoops 
400kg - 600kg 3 ½ scoops 
Over 600kg  4 ½ scoops
 
1 level (50ml) scoop of Ultimate Gastro-Ease® weighs approximately 36g
 

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.
