What do sugar-free products contain?

Sugar-free products contain sugar substitutes, some natural and some synthetic. Artificial sweeteners are saccharin, aspartame, sucralose, neotame, acesulfame potassium, and stevia. Artificial sweeteners are compounds with sweetness 300-500 times that of sucrose (table sugar). As a result, less sweetener is required, energy contribution is often negligible and blood glucose levels are not effected.
