Stevia is a natural sweetener derived from the leaves of the Stevia rebaudiana plant, native to South America. It is known for being much sweeter than sugar, yet it contains little to no calories. This makes it a popular choice for people looking to reduce their sugar intake or manage their weight. The sweetness in stevia comes from compounds called steviol glycosides, which are extracted from the leaves. Unlike artificial sweeteners, stevia is considered a natural product, and it has gained popularity among those seeking healthier alternatives to traditional sugar and synthetic sweeteners.
