Purina® Outlast® Gastric Support Supplement is scientifically developed to help support your horse’s gastric health and comfort. Designed by PhD equine nutritionists and backed by extensive research, Outlast® features a proprietary mineral complex that helps buffer stomach acid and maintain optimal gastric pH — especially during stressful situations such as travel, training, competition, stalling, weaning, or environmental changes.
Up to 90% of active horses may experience gastric discomfort, which can negatively affect attitude, appetite, and performance. Outlast® supplement works quickly — proven in simulated gastric environments to begin buffering in as little as two minutes. Its unique honeycomb-structured mineral complex, derived from natural calcium and magnesium sources, increases surface area to enhance buffering capacity and support gastric wellbeing.
Easy to feed and highly palatable, Outlast® can be top-dressed onto your horse’s regular feed or given alone as a snack before stressful events. It’s suitable for horses of all ages and activity levels and is trusted nationwide by horse owners seeking proven gastric support.
