Does all stride gum have aspartame?

Not all Stride gum contains aspartame. Some varieties are sweetened with sugar and do not contain aspartame. To determine whether a specific flavor of Stride gum contains aspartame, you can check the ingredient list on the packaging. The ingredients will be listed in descending order by weight, so if aspartame is present, it will be near the beginning of the list. Alternatively, you can look for a "sugar-free" label on the packaging, which would indicate that the gum does not contain any added sugar or artificial sweeteners, including aspartame.
