Superlyte rapidly replaces electrolytes in exactly the same ratio as they are lost in equine sweat. When horses perform high intensity, short duration physical exercise they lose considerable amounts of body fluids through sweating. These horses lose electrolytes in the ratio of 2 Sodium: 2 Chloride: 1 Potassium. Scientists have shown that horses racing over distances of 1 to 2 miles (1600 to 3200 metres) may lose up to 10 litres of body fluid through sweating. Further electrolyte losses will also occur through daily exercise and particularly during hot weather. Deficiencies in electrolytes can lead to under performance, dehydration, muscle cramping (‘tying-up’) and / or heat exhaustion. Regular electrolyte supplementation is vital for a horses well being and optimum athletic performance.
