This electrolyte paste is an oral supplement for horses, delivered in a pre-measured syringe for easy dosing. The formula combines sodium chloride, potassium, magnesium and calcium in a palatable apple-flavored base so it can be given directly into the mouth without mixing into feed or water. It is intended for use during exercise, travel, hot or cold weather, and other situations where a horse sweats or experiences stress, and can also be given proactively ahead of activity. Fresh water should remain available whenever this product is used, since electrolyte supplementation is meant to work alongside normal drinking rather than replace it. Each syringe is dosed in small increments to reduce waste from product being dropped from the mouth, and the case groups multiple individually usable syringes together. No mixing, assembly or refrigeration is required before use.
