Stress-Dex® SB is a balanced electrolyte powder for all horses, to be used as a supplemental source of calcium, phosphorus, salt, potassium, and magnesium. It comes as a highly palatable, appetizing apple flavored powder that contains a balanced blend of electrolyte salts without all the sugar. It helps control electrolyte imbalances and losses and replenishes the body of lost electrolytes during periods of stress, illness, physical exercise and in hot, humid weather. Also great for winter use when horses naturally drink less water. Feed 1-2 ounces per day, in one dose or divided into 2 doses. Mix with feed or water. The 4 lb tub provides one horse with up to a 64 day supply.
