What the Science Says
Stevia is a natural sweetener derived from the leaves of Stevia rebaudiana. Animal research suggests it may help protect the liver by reducing fibrosis-related pathways and blocking scar tissue formation. However, the available evidence comes only from animal studies and agricultural research — no human clinical trials are represented in the provided data.
What It Doesn't Do
Not proven to treat or prevent liver disease in humans. No clinical evidence it controls blood sugar in people. Not a weight loss supplement. Don't confuse its use as a sweetener with any proven therapeutic benefit.
Evidence-Based Benefits
Reduced liver scarring and fibrosis markers in a rat model of cirrhosis.
