What is it?

Stevia is a natural sweetener. It’s made from the leaves of Stevia rebaudiana, a plant in the sunflower family.

Stevia supplements come as liquid extracts, powders, and tablets.

What are the potential uses and benefits?

Stevia is used to:

  • Sweeten foods and beverages
  • Lower high blood pressure
  • Help you lose weight
  • Treat diabetes

Stevia also has other uses, but doctors have not studied them to see if they work.

It’s generally safe to use stevia as a sweetener. Talk with your healthcare provider before taking stevia supplements. Herbal supplements are stronger than the herbs you would use in cooking.

Supplements can also interact with some medications and affect how they work. For more information, read the “What else do I need to know?” section below.
