Stevia (Stevia rebaudiana) is a natural, calorie-free sweetener derived from the leaves of the stevia plant, native to South America. It’s about 200–300 times sweeter than sugar due to compounds called steviol glycosides, making it popular for those seeking low-calorie alternatives. Stevia is also favored for its potential health benefits, including supporting blood sugar management and reducing calorie intake, though it has a slightly different taste than sugar. Often used in beverages, baking, and as a tabletop sweetener, it’s a versatile option for health-conscious individuals.
