Saccharin is a popular non-nutritive (low-calorie) sweetener that has been used for over a century. It is used in a wide range of low-calorie and sugar-free foods and beverages, including tabletop sweeteners, baked goods, jams, chewing gum, canned fruit, candy, dessert toppings and salad dressings. It also is used in cosmetic products, vitamins and pharmaceuticals.

Saccharin has been reviewed and determined to be safe by the FDA, the Joint Expert Committee on Food Additives of the Codex Alimentarius Commission (JECFA) and the Scientific Committee for Food of the European Union (SCF). Saccharin is approved for use in food and beverages in more than 100 countries around the world.
