Mayo Clinic dietitian Katherine Zeratsky, R.D., L.D., and colleagues answer select questions from readers.

Answer

Stevia is an herb that's used as an artificial sweetener in certain parts of the world. Stevia extracts can be hundreds of times sweeter than sugar. Stevia has virtually no calories and doesn't raise blood sugar levels. Some studies suggest that stevia may help treat type 2 diabetes and high blood pressure. Side effects of stevia are generally mild, such as muscle weakness, dizziness and nausea. But questions about the risks of stevia linger, including possible effects on the reproductive system and kidneys. In the United States, stevia is available only as a dietary supplement. The Food and Drug Administration hasn't approved the use of stevia as an artificial sweetener or food additive. If you're considering taking stevia as a dietary supplement, consult your doctor about the possible risks and benefits.
