Note that there are some Gels that are not [[Maltodextrin]] based, such as the old formula Clif Shots use brown rice syrup.
==Caffeine in Gels==
[[Caffeine ]] not only improves performance, it also increases the absorption of sugar from the gut, so it will make Gels quicker acting.
==Blood sugar and Insulin==
If you take a gel or other fast acting carbohydrate at rest, your blood sugar will rise and your pancreas will release insulin. Immediately after exercise, the insulin will cause the sugar to refuel the muscles, and at other times it will form fat. However, during exercise the fast acting carbohydrate will be directly absorbed by your muscles and not trigger insulin.
