Maltodextrin is a complex carbohydrate although it has a relatively high Glycemic Index meaning it is rapidly absorbed by the body in a manner similar to Dextrose.
As it is easily absorbed by the body, it provides a rapid increase in energy levels as it raises blood sugar levels and restores glycogen quickly after consumption.
Maltodextrin is a popular carbohydrate which is often combined with dextrose to optimize glycogen replenishment and performance.
