Does Sonic Do Sugar-Free Slushes?

One of the menu items that Sonic is most famed for is its slush drinks. Think sweet, icy slushy in a variety of colorful and yummy flavors. The bad news is that, even though slushes can be flavored with sugar-free syrup, no slush can be sugar-free.

You can add sugar-free syrup to your slush to flavor it but the plain no syrup slush base still contains sugar. On the nutritional menu, it states “all slushes contain sugar” – at least they are transparent about it.

Most of the sugar in a Sonic slush comes from the slush base and not the syrup. For example, the small contains 48g of sugar. Some of the regular syrups can contain as little as 3g of sugar in a small serving, so whether you order a slush with the sugar-free syrup or sugared syrup won’t make a huge difference. Most of the sugar will still come from the slush base.
