Hygain Regain is a rapid electrolyte replacer formulated for horses to replace body salts lost during exercise, hot climatic conditions and as an aid in the treatment of dehydration, hypochloraemia, and alkalosis. When horses sweat, they lose significant amounts of electrolytes including sodium, chloride, potassium, magnesium and calcium. Excessive electrolyte depletion can cause muscle fatigue, muscle damage and dehydration resulting in poor performance and conditions such as hyponatremia, hypochloraemia, and alkalosis. Regain is a concentrated blend of five key electrolytes, developed specifically to replenish the horse, supporting body and muscle functions. Regain is suitable for all climates and conditions and levels of equine sports and disciplines.
