Horses that graze on sandy ground may ingest sand and dirt that may accumulate in the intestinal tract, causing stomach discomfort and digestive issues. Psyllium seed husks combined with water form a gelatinous substance that flows through the horse's intestinal tract, helping to decrease sand and dirt accumulation in the gut. For best results, use the UltraCruz Psyllium Fiber Supplements for Horses as a monthly supplement to aid in the intestinal cleansing and to support normal digestive function in your horse. For horses that cannot digest molasses or do not need extra sugar, we recommend using our UltraCruz Equine Pure Psyllium for horses, which provides the benefits of psyllium supplement, while containing 100% pure psyllium seed husk. Designed as an easy-to-use pellet, these horse digestive supplements are convenient to feed to your horse.
