Stevia extract (leaf)

Stevia extract is derived from the leaves of the plant, Stevia rebaudiana, which has been used by South Americans for over 200 years as a sweetener 1, 2, 3. These leaves are used to sweeten beverages or are chewed for their sweet taste, dried, and may be known as “sweet herbs” 2. Stevia extracts are used as natural sweeteners and dietary supplements in a number of countries, including the United States 1, 2, 4. Much of the sweetness of the stevia leaves are attributed to the presence of glycosides, including rebaudioside A, or Reb A, which is about 300 times sweeter than sucrose (sugar) 3. High purity stevia extract provides zero calories since it is not metabolized 1, 2.
