From Organic Stevia Leaf

Stevia leaf extract comes from the leaves of the Stevia rebaudiana plant, native to South America. The sweet compounds, called steviol glycosides, are extracted from the leaves and purified. These extracts are then often processed to create a highly concentrated, calorie-free sweetener.

Stevia leaf extract is used as a high-intensity, zero-calorie sweetener in a wide variety of food and beverage products. Manufacturers add it to reduce sugar and calorie content while maintaining sweetness. It is commonly found in powdered drink mixes, tabletop sweeteners, baked goods, and dairy products.

Stevia leaf extracts are Generally Recognized As Safe (GRAS) by the FDA for use as a sweetener. International bodies like JECFA and EFSA have also evaluated steviol glycosides and established acceptable daily intake levels. At typical consumption levels, stevia leaf extracts are considered safe. Some individuals may experience mild digestive upset, but this is not common.
