Dextrose (Corn Sugar) also known as glucose is a monosaccharide or simple sugar. For reasons I can only guess at, it is popular with body builders and "natural food" people. Which is really odd since it is made by chemically breaking down corn starches, unlike cane and beet sugars that are natural.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
