NUUN just reformulated most of their products, and while I haven't tried the new formulation, they've removed the artificial sweeteners, foaming agent and preservatives, and added more sodium, so next time I order, I may try NUUN Active. I've been using GU Hydration Drink Tabs, which don't supply calcium or magnesium. For the running I do, I'm able to get enough magnesium from supplements I take regularly, but I think if I were cycling as I used to or ultra running - i.e., if I were out for more than around five hours at a time - I'd probably need to supplement calcium and magnesium during my workouts also. That would be a reason to use the new NUUN over GU.
As far as your calories, how do you do with long chain carbohydrates? Most of the energy products available emphasize maltodextrin over simple sugars; most of them have so little simple sugar that they add stevia and/or a small amount of sucrose just for a sweet flavor. Skratch Labs is an exception; all its calories come from simple sugars.
I'm not sure who we have participating currently in this forum, who's diabetic. You might be best to talk it over with a sports nutritionist who has expertise with diabetes, or a diabetes-focused nutritionist who has experience with endurance athletes. It's important that you be able to sort out how your body processes sugars and what happens to your insulin level during endurance activity. Based on the experience of many of us with other types of issues, a lot of health professionals who deal with people with chronic health issues have no idea what to do with endurance athletes, or what happens in our bodies during exertion.
