Recognized as the "BEST BUY and Overall Choice" by Horse Journal (aug 1999) & Equine Professionals Precious resources of essential electrolyte salts and minerals are depleted during exercise, stress, and performance. Exer-Lyte™ replenishes these valuable electrolytes and minerals and restores their natural balance. Electrolytes are lost when a horse sweats. The need for an electrolyte supplement increases when work, stress and heat are added to your horse’s daily routine. The more your horse sweats, the more your horse needs Exer-Lyte™. Dehydrated horses have a reduced thirst response. They typically will not drink water containing electrolytes. You can restore the thirst response and encourage water intake by top dressing your horse’s feed with Exer-Lyte™ . Exer-Lyte™ is designed to naturally replenish valuable electrolytes lost during exercise, work, stress, endurance and performance. Horses that are fed balanced diets and are not under work stress conditions generally do not require electrolyte supplementation. They meet their needs naturally. Sodium is the exception and all horses, regardless of working conditions, should be fed free-choice salt. Avoid feeding more than one mineral supplement to minimize potential mineral interactions.
