Maltodextrin is a high quality complex carbohydrate sourced from corn starch which provides a great source of fast release energy. Although Maltodextrin is a complex carbohydrate, it rates quite highly on the Glycemic index (GI) just below simple carbohydrates like Dextrose. This means it causes your blood sugar levels to rise quickly, providing a rapid increase in available energy levels. Maltodextrin is the ideal carbohydrate for use whenever a quick and easily accessible source of energy is required and allows your body to replace used glycogen stores rapidly.
