Isotonic Sports Energy & Electrolyte Drink.


Iso Fuel Sports Energy Drink:

is a carbohydrate and electrolyte drink that delivers maximum and enduring energy and replenishes lost electrolytes. It is made mainly with natural ingredients that are stable, rapidly absorbed and easy on the stomach, even during intense exercise and race effort.

uses a balanced matrix of maltodextrin, a low GI carbohydrate complex for lasting energy and fructose and dextrose, two high GI carbohydrates for fast energy. It uses real fruit flavours that are light and not too sweet.

EFSA opinion on carbohydrate-electrolytes and endurance performance:

The Panel concludes that a cause and effect relationship has been established between the consumption of carbohydrate-electrolyte solutions and maintenance of endurance performance.

The Panel considers that in order to bear the claim a carbohydrate-electrolyte solution should contain 80-350 kcal/L from carbohydrates, and at least 75 % of the energy should be derived from carbohydrates which induce a high glycaemic response, such as glucose, glucose polymers and sucrose. In addition, these beverages should contain between 20 mmol/L (460 mg/L) and 50 mmol/L (1,150 mg/L) of sodium, and have an osmolality between 200-330 mOsm/kg water. The target population is active individuals performing endurance exercise.
