Some say it works, some say no better than other things. Interesting idea anyway, if one rides at intensities which demand that many calories/hour. Note that they tested this mix vs. glucose, but not vs. pure maltodextrin. Big difference and the usual hyped bias. My practice is not to put electrolytes in my drink, but rather to take them separately. IME the need for them varies with the temperature, whereas the need for food varies with output level. Throw in a little malto, throw in a little fructose if you want, and flavor it up with a little Hammer Gel. The Espresso flavor contains caffeine. Or add a little Starbucks Via, which dissolves well in cold water.
