If maltodextrin is a complex carbohydrate, why use it PW?
Maltodextrin is a glucose polymer, a string of glucose units put together, similar to the protein peptide. It is therefore, by definition, a complex carbohydrate. However its more complex nature does not slow digestion, and thus, both the glycemic index (GI) and insulin index (II) remain high. Maltodextrin is the absolute best carbohydrate to consume during exercise for rapidly delivering blood glucose and for muscle glycogen recovery. It is also best for fluid uptake.
