Stevia is typically two hundred to four hundred times sweeter than regular table sugar depending on the specific extract concentration and brand processing. Because it is intensely sweet, only a tiny fraction of a gram is needed to match the sweetness level of a full teaspoon of sugar. Stevia is a popular zero calorie plant based sweetener derived from the leaves of the Stevia rebaudiana plant. It provides a sweet flavor profile without spiking blood glucose levels.
