Stevioside is a natural sweetener extracted from stevia. Its core function is to provide a sweet taste with high sweetness and low calories. It is approximately 200-300 times sweeter than sucrose, so only a small amount is needed to meet the demand for sweetness. Moreover, it generates almost no calories, making it suitable for people who need to control sugar intake (such as diabetics and those trying to lose weight) as a substitute for sucrose.
