Rebaudioside A is widely used as a natural sweetener in the food and beverage industry due to its high sweetness intensity and low-calorie content. It is a key ingredient in sugar-free and reduced-sugar products, including soft drinks, desserts, and baked goods, catering to health-conscious consumers and those managing diabetes. Its stability under high temperatures makes it suitable for cooking and baking applications. Additionally, it is incorporated into dietary supplements and oral care products like toothpaste and mouthwash for its sweetening properties without promoting tooth decay. Its natural origin and safety profile have also led to its use in pharmaceuticals to improve the taste of syrups and chewable tablets.
