Why do you include stevia in Promax Lower Sugar?

Stevia is a plant (specifically, a member of the chrysanthemum family) native to portions of northeastern Paraguay. Its leaves contain glycosides which account for its incredible sweetness, and have been used to sweeten foods and beverages for more than 200 years. Stevia is used in Promax Lower Sugar  bars as a non-nutritive sweetener to make the bar taste great while reducing the amount of sugar in the bar. It is an alternative to artificial sweeteners like sucralose, saccharin and aspartame.
