Electrolyte Plus is a blend of essential electrolytes; sodium, potassium, calcium and magnesium. Electrolytes help provide the electrical energy necessary for many functions within the human body, including nerve impulse transmission and myofibril contractions. When exercising, these nutrients are generally lost through sweating, especially when exercising in hot weather; excessive loss of electrolytes can severely impede performance. The addition of electrolytes to carbohydrates can help maintain salt levels in the body and maintain proper hydration and enhance the absorption of water during physical exercise. A loss of just 2 percent of body weight through dehydration can dramatically impede and negatively affect your physical performance. This also contains 6 milligrams of magnesium which can contribute to electrolyte balance. It is suitable for anyone taking part in intense, physical exercise where there is abundant fluid loss.
