UltraCruz Equine Pure Psyllium Supplement for Horses, an equine supplement for horses that graze or eat from the ground. Equine pure psyllium is made from 100% natural pure psyllium seed husk in the form of a palatable powder to help support normal gut function in horses without the addition of extra fillers and flavoring. When a horse grazes on sandy ground, it may ingest the sand and dirt, which accumulates in the intestinal tract. Combined with water, psyllium husks form a gelatinous substance that flows through the horse's intestinal tract. This substance may naturally help support the removal of sand from the ventral colon and other parts of the intestinal tract and help in reducing the risk of sand colic. For best results, use UltraCruz Equine Pure Psyllium Supplement for Horses for horses as a monthly supplement to help sand removal and support normal digestive function in your horse.
