Can lower blood sugar

A plant whose leaves contain very sweet compounds, used as a zero-calorie sweetener.

Did you know? Stevia's sweet compounds are about 200 to 300 times sweeter than table sugar, yet they add almost no calories.

What it may help, and how strong the proof is

  • Blood sugar. Small trials suggest stevia may lower blood sugar a little. The studies are short and mixed in quality.
    Early proof
  • Blood pressure. A few small trials show modest drops in blood pressure. Larger, longer trials are needed.
    Early proof
  • Weight. Swapping sugar for stevia cuts calories. Good trials on stevia alone for weight loss are lacking.
    Traditional proof

Mixing with other things

The honest take

Stevia is a useful zero-calorie sweetener. Its blood sugar and blood pressure effects come from small, short trials with mixed results. Many stevia products are mostly sugar alcohols like erythritol, so read labels.
