Heavy Sweat is formulated to replace salts lost during exercise or exertion. Our balanced electrolyte supplement is an easy way to ensure horses are not lacking in these vital salts and to effectively replenish and hydrate your horse. Horses can lose salts even if they don't show outward signs of sweating, especially in hot humid weather, when travelling, or when they are slightly unfit, nervous or agitated. Why choose Heavy Sweat? Vital for stamina and recovery after exercise. Helps reduce muscle fatigue. Free from glucose and fillers. Horseman's tips: "The pinch test: Gently pull out a pinch of skin on your horse's neck or shoulder and notice how quickly it springs back. If the skin returns quickly into place, the horse's fluid balance is fine. If the skin remains elevated for more than a few seconds, it is moderately dehydrated. The longer the skin remains elevated, the more dehydrated the horse."
