Electrolyte salts provide the needed electrolytes to maintain depleted body fluids if your horse is under stress or in hard training or competition. Delicious apple-flavored granules deliver sodium, calcium, potassium, magnesium, and trace minerals - nutrients that may be lost by dehydration. A boon to competition, working, and endurance horses. These delicious electrolytes are in granulated form to make feeding easy. May be put into drinking water or in daily feed ration in place of salt. 1-oz scoop included. Apple flavor. For horses.
