Why did you include 2 types of carbs (maltodextrin & fructose)?
Your gut has a limited number of receptors to transport carbohydrates into your bloodstream to be used for fuel. So by using a drink that contains only one source of carbs you will overwhelm those receptors, transport will slow down, and those extra carbs sitting in your gut will cause water to leave your bloodstream to enter your gut. This can lead to abdominal pain, dehydration and decreased performance during exercise. Studies have shown that by using two different sources of carbohydrates (maltodextrin and fructose, in this case) that are absorbed by different receptors you get increased absorption, and thus supply more energy, faster, to metabolizing tissues.
