Wasn't much carbohydrate in the couple of items I checked or they gave the nutrition info for. Did have what to me is too much sodium and other electrolytes. So if you don't adjust for carbs, then it's going to be lacking carbs when compared to your gatorade mix.
If you are trying for low carb, then I don't know. Low carb is not my thing, and especially when riding where I'm looking for 100 to 200 Calories per hour...... roughly.
