Stevia, a natural zero-calorie sweetener derived from the Stevia rebaudiana plant, is widely used as a sugar substitute. It offers benefits such as blood sugar regulation, weight management, and tooth decay prevention. While generally safe in purified forms, it may cause side effects like digestive discomfort and allergic reactions in some people. Stevia is a valuable alternative to sugar for those looking to reduce calorie intake and improve health but should be used thoughtfully alongside a balanced diet.

Stevia sweeteners are safe when derived from high-purity steviol glycosides approved by global regulators like the FDA and EFSA. Whole leaf extracts lack approval. Purified stevia is a natural, no-calorie sweetener ideal for reducing sugar intake, suitable for diabetics, children, and pregnant women when consumed within daily intake limits.
