Choosing Supplements to Support Your Horse’s Ulcer Care Plan

Written by Briony Witherow MSc RNutr. FHEA

While diet and management are the most important factors in ulcer prevention, supplements can offer additional support. Here’s how to choose the right ones.

Key Supplements for Ulcer Support

• Antacids (e.g. Gastro-Mag): Contain magnesium hydroxide and sodium bicarbonate to buffer stomach acid.
• Beta Glucans: Found in yeast and cereals, they help form a protective layer over the stomach lining.
• Pectin: A natural gel-forming substance that protects the stomach lining from acid exposure.

How to Integrate Supplements into Your Plan

• Pre-exercise meals – Add an antacid supplement like Gastro-Mag before work to reduce damage potential from acid splash.
• During stressful periods – Use targeted supplements when your horse is travelling, competing, or undergoing changes in management.
• Long-term support – Combine supplements with a fibre-rich diet to maintain stomach health.

Conclusion

Supplements can enhance an ulcer care plan but should not replace an appropriate diet and management. Use them alongside high-quality forage, slow feeding strategies, and careful starch control for best results.
