Steviol glycosides are natural sweeteners derived from the leaves of the stevia plant, specifically from the species Stevia rebaudiana. These compounds are known for their intense sweetness, which can be up to 300 times sweeter than sugar, making them a popular alternative for those looking to reduce sugar intake. They are often used in food and beverages as a low-calorie sweetening option. The primary steviol glycosides include stevioside and rebaudioside A, both of which are extracted and purified for commercial use. These sweeteners are considered safe for consumption and have gained approval from various health authorities, including the FDA and EFSA, for use in food products.
