Do people have allergic reactions from acesulfame potassium?
There is no evidence that acesulfame potassium causes allergic reactions. In the 15 years the sweetener has been on the market around the world, no substantiated allergic reactions have been reported. Although the ingredient contains sulfur, a recognized allergen, the structure of the sulfur is different from that of sulfites and sulfa drugs which have been known to cause allergic reactions.
