This powder blends psyllium with probiotics, vitamins, minerals, and biotin to support digestive lubrication in horses. It can be mixed with water into a suspension for stomach-tube administration in horses that have consumed a large amount of sand, dirt, or indigestible feedstuffs, or top-dressed onto regular feed as a follow-up or maintenance measure. Suggested usage rates are based on a 1,000 lb horse and should be adjusted according to actual body weight. The product is intended for equine use only and should not be fed to cattle or other ruminants. It should be stored in a dry area within a controlled temperature range and resealed promptly after each use to help preserve product quality.
