Is Sonic Cherry Zero-Sugar Syrup High in Histamine?

Sonic Cherry Zero-Sugar Syrup

Low histamine

This cherry flavoring syrup is low in histamine, made mostly of flavors, acids, and sucralose.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

This is a sugar-free cherry syrup built from citric and malic acids, artificial and natural flavors, sucralose, and coloring.

No flagged drivers — nothing in this syrup is aged, fermented, cured, or a classic liberator food, so it stays low.
Simple flavoring base — the acids and sweetener here are just for taste, and none of them carry meaningful histamine.

This is one of the gentler add-ins on the menu, so it is an easy pick.
