DOES IT WORK?
Steviol glycosides (rebaudioside A, stevioside, etc.) are the sweet compounds extracted from Stevia rebaudiana leaves. They're 200-300 times sweeter than sugar with zero calories. In supplements, they make products palatable without adding sugar or artificial sweeteners. Some research suggests minor blood pressure and blood sugar benefits, but the amounts used as sweeteners are far too small for therapeutic effects. Safe and effective as a sweetener.

Mechanism of Action
Steviol glycosides bind to sweet taste receptors (T1R2/T1R3) without being metabolized for energy. Gut bacteria cleave the glycoside bonds to release steviol, which is glucuronidated in the liver and excreted. At higher doses, stevioside may stimulate insulin secretion and relax blood vessels.
