We always heard about isotonic drink but do we really know about it? Isotonic drink is one category of sport drink. It have an osmolality of 280 to 330 mOsm/kg (measure to particle carbohydrat, sweeteners, electolytes and preservatives in a fluid). The drink popular among athletes because it can approximates body’s natural fluid balances.
Isotonic drinks don’t contain caffein and prevent dehydration.

Benefits of Isotonic Drinks
Isotonic drinks quickly replace fluids lost by sweating, and supply a boost of carbohydrate, so are usually the preferred choice for athletes, distance runners and those participating in team sports events.
Isotonic drinks provide the same amount of sodium as blood plasma. Drinking plain water can be a poor choice when a high fluid intake is necessary, as it contains none of the carbohydrate or electrolytes that promote a more rapid recovery after a session of strenuous exercise.
Isotonic drinks contain carbohydrates to help you to stay energised whilst also helping to keep you hydrated by replacing fluid and precious electrolytes (salts) which are lost through sweat; helping you to avoid the negative effects of dehydration during and after exercise. Even moderate intensity exercise will create sweat resulting in a loss of electrolytes and energy. An isotonic drink has a similar carbohydrate and electrolyte concentration to your body, meaning that your body will absorb them faster than water alone.
