Orbit sugar-free gum's primary ingredients are gum base, sugar alcohols and flavorings. The sugar alcohols include sorbitol, xylitol, mannitol and glycerol. These ingredients comprise 98 percent of the gum; the other two percent contains artificial sweetener, artificial coloring, starch and preservatives.
Wrigley's does not list the specific natural and artificial flavorings used in Orbit. The colors and artificial sweeteners used vary based on the gum flavor; for example, Original Bubble Gum flavor uses Red 40 and Red 40 Lake as artificial coloring. Its artificial sweeteners are aspartame and acesulfame potassium.
The company does not list a specific calorie count in its nutritional information, but states that each piece of Orbit contains fewer than five calories. Calories in Orbit come from the sugar alcohols, and this small amount of carbohydrate is the only nutrient found in Orbit. All Orbit flavors are sugar-free.
In addition to its Orbit brand, Wrigley's sells gum under two related brands: Orbit for Kids and Orbit White. Orbit for Kids is available in Original Bubble Gum and Grape flavors; Orbit White is available in Bubblemint, Peppermint and Spearmint flavors.
