Does pedialyte come in a powdered form, or do you have to buy the pre-mixed kind?

E-caps makes a straight electrolyte replacement called Endurolytes. You can take them as capsules or mix the powedered form into your water, although the end result tastes like salt water.

My question is, if you can only consume x grams of carbohydrate without dehydrating yourself, how do you keep yourself from bonking? On long rides, you need both sufficient hydration and nutrition. No matter what, you're going to increase the concentration of carbohydrate in your stomach at some point, and will need water to digest that. It's unavoidable. I wish he's explained a little more about how the maltodextrin figures into the equation.

A friend of mine got hyponatremia drinking Powerade on a hike of the grand canyon. The ER doc said they've taken to calling it "Powerade syndrome" because Powerade has so little sodium - less than half that in Gatorade. It never occurred to me that even in the commercial grocery store drinks, there can be a substantial difference.
