Gastro S helps to restore a healthy gut for minor gastric discomfort. In addition, more importantly won’t irritate!

What are stomach ulcers in horses?

Stomach ulcers are essentially an acid burn to the stomach lining and common place with horses. Hydrochloric acid is constantly produced in the lower portion of the horses’ stomach. However, if this acid splashes to the upper portion it is not protected and is therefore prone to ulceration.

How to help gastric discomfort?

Healing the gut requires a coating to allow the stomach to repair, essentially a band aid like that of a plaster on a cut!

Gastro-S supports in comforting against gastric discomfort in the ulcer prone horse instantly soothing the stomach (gut) providing a natural jelly mucilage material that coats and aids to support gut health. Ensuring constant gut fibre is also imperative to gut health and repair. 

In more severe cases of gastric discomfort your horse or pony may need a course of Omeprazole to turn off the acid pump, which will allow the gut to heal. This is available through your vet.
