Crown Sport Nutrition HyperDrink 90 neutral flavoured drink is a premium quality sports drink powder with an ideal composition of carbohydrates and sodium, nutrients needed to enhance performance in training and long duration and/or high-intensity competitions. In a single 500 ml serving you will get 90 g of carbohydrates plus extra sodium (approx. 208 mg).HyperDrink 90 contains the ideal blend, according to science, of carbohydrates, Maltodextrin and Fructose, in a 1.25:1 ratio (commonly 1:0.8). It has been shown that in prolonged exercise the use of carbohydrates that are absorbed in the gut by different transporters (known as GLUT) is the only way to increase the rate of assimilation and oxidation of exogenous carbohydrates above 60 g/hour (Currell, K. et al., MSSE. 2.008; Earnest, C.P. et al., JSCR. 2.004). Research suggests that the ideal way to do this is to combine a source of glucose (in this case maltodextrin) with fructose.
