That's probably because Nuun doesn't have simple sugar. Gatorade, and other sports drinks, depend on sugar for energy, but even those companies are coming out with alternative drinks with low sugar content. The risks of too much sugar are real (long and short term), and the benefits to most people are questionable because of the fatigue that comes after the sugar rush.

Personally, I've noticed both the initial high and the fatigue that follows, and due to my high blood sugar I have to be conscious of the risks.
