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.

In 1997, the U.S. government announced that recent human studies had shown that there is no link between saccharin and bladder cancer. In December 2000, the President signed federal legislation to remove the saccharin-warning label that has been required on saccharin-sweetened foods and beverages in the U.S since 1977.

Saccharin is the same kind of sweetener found in Sweet N' Low®.
