Steviol glycosides are a class of sweet compounds that are extracted from the leaves of the Stevia rebaudiana plant. They are commonly used as a natural, low-calorie sweetener in food and beverage products. Steviol glycosides are up to 400 times sweeter than sugar, but they have no calories and do not raise blood sugar levels, making them a popular alternative to sugar for people with diabetes or those watching their weight.
Stevia extracts have been used for centuries in South America, and steviol glycosides have been approved as a food additive in many countries around the world, including the United States and the European Union. They are typically sold under brand names such as PureVia, Truvia, and SweetLeaf.
While steviol glycosides are generally considered safe for human consumption, some studies have suggested that they may have potential negative effects on fertility and reproduction in high doses. However, more research is needed to fully understand the potential risks and benefits of consuming steviol glycosides. As with any food additive, it is important to consume them in moderation and as part of a balanced diet.
