Top riders and horse people like Laura KlaphakeNayel Nassar and Janne Friederike Meyer-Zimmermann know that the stomach health has a great influence on the well-being and performance of their horses. For them, Equine 74 Gastric, makes the difference. 

What are the signs that my horse has stomach ulcers?

Your horse has been behaving strangely in the past, got a dull coat and stopped eating its hay? Here you get to know the 22 symptoms of gastric ulcer in horses. If you recognise several of these symptoms, please contact your vet. A gastric ulcer can only be clearly diagnosed by a gastroscopy. If they are located in the non-glandular part of the stomach, omeprazole is recommended for the horse in many cases. But how does omeprazole work?

Acid-producing cells, such as the vestibular cells in the stomach, need protons, such as potassium and hydrogen, to produce pepsin and HCl. These substances are transported via a proton pump. The active ingredient omeprazole is a proton pump inhibitor and belongs to the group of stomach acid blockers. This inhibition reduces gastric acid secretion by up to 99 %, so that the mucous membrane no longer comes into contact with HCl and has time to regenerate. 

When is omeprazole useful?

In acute, bleeding gastric ulcers in the squamous part of the stomach, the use of omeprazole is absolutely recommended. In order to document the healing process of a gastric ulcer, a control gastroscopy is useful. A gastroscopy is stressful for many horses, as long periods of fasting are a prerequisite for an effective examination. Talk to your vet about the pros and cons of gastroscopys and when a follow-up is appropriate. In addition to the endoscopic imaging procedure, you should also monitor your horse closely for any improvement in symptoms. Premature discontinuation of omeprazole can lead to a relapse. 

Equine 74 Gastric counteracts the effects of constant stress-related acid problems with high mineral acid buffering. Learn more.

What happens after a omeprazole treatment in horses? 

To prevent a relapse after the omeprazole cure, you should look for a long-term solution, because medication should not be fed permanently. The risk of getting a gastric ulcer again can never be reduced to 0 %, but you can take some prophylactic measures. Especially husbandry and feeding have a great influence on the health of your horse.

3 important tips to prevent stomach ulcers in horses


  • Feed roughage freely or at least 1.5 kg/100 kg body weight/day
  • Feed low-starch concentrated feed
  • Spread the concentrated feed ration over several portions a day 
  • Prevent feeding breaks of more than four hours (e.g. by feed racks or hay nets)
  • Feed roughage before concentrates
  • Water of good quality


  • Make herd constellations homogeneous (avoid rivalries or rank fights)
  • Relocate unpopular neighbours in the stable
  • Quietness in the stable lane (e.g. do not let the radio play)
  • Ensure plenty of free movement


  • Adjust the workload
  • Extensive paces during training

Equine 74 Gastric as a long-term alternative to omeprazole

In the case of acute, bloody gastric ulcers, the administration of preparations containing omeprazole is recommended. This gives the mucous membrane the opportunity to regenerate. If you want to switch to a natural supplement like Equine 74 Gastric, it is important to phase out omeprazole. This way, the stomach slowly gets used to the production of gastric acid again.

We recommend that our customers start feeding Equine 74 Gastric about two weeks before they plan to stop taking omeprazole. For this purpose, a dosage of one teaspoon of Equine 74 Gastric should be started. Until omeprazole is discontinued, the amount of Equine 74 Gastric can then be increased to the recommended amount of 50 g per day (500 kg warm-blooded horse). It is best to divide the feeding into two to three rations per day. If this is not possible, we recommend feeding before the longest feeding break, which is usually in the evening.

I read some of the testimonials on World of Showjumping, and I totally believed in the product. I think it is a good sign if not just representatives of the brand, but also top riders and trainers who actually use the product say that the product works.

To avoid a relapse after a course of omeprazole, a stomach supplement should be fed for support during the transition. Equine 74 Gastric can be used both as a 6-week cure and as a permanent part of the feeding routine. In order to achieve lasting therapeutic success, the primary cause must be eliminated. 

Why is Equine 74 Gastric the right gastric supplement for my horse?

Are you looking for a long-term solution that is free of chemicals and cost-intensive medication?

Equine 74 Gastric is based on red algae harvested off the coast of Iceland, which counteracts the excess acidity in the horse's stomach caused by feeding and stress. The organically certified formula is characterised by a high bioavailable calcium content. This increases the acid buffering capacity, which is 2.5 times higher than comparable limestones and thus binds stomach acid. Equine 74 Gastric is a gastric acid buffer that only binds the excess stomach acid so that the stomach acid needed for the digestive processes is still present. In this way, the pH value in your horse's gastric becomes more and more balanced. 

The advantages of Equine 74 Gastric at a glance

  • 2.5 times higher acid buffering capacity than supplements derived from limestone
  • Large amounts of highly bioavailable calcium and magnesium released in the horse's gastric
  • Special sponge structure with a large surface area which is slowly decomposed in the horse's stomach so that the stomach acid can be buffered over a longer period of time
  • The function of the gastric acid is maintained
  • Available in three variants (powder, pellet, granulate)
  • Doping-free
  • 100 % natural
  • Less then 2€ per day
