What Is Acesulfame Potassium (Ace-K)?

A calorie-free artificial sweetener approximately 200 times sweeter than sucrose. It is heat-stable, making it suitable for baking and cooking. Often blended with other sweeteners like aspartame or sucralose to mask its slightly bitter aftertaste.

Mechanism of Action

Ace-K is not metabolized by the body and is excreted unchanged through the kidneys. It stimulates sweet taste receptors (T1R2+T1R3) on the tongue. Some animal studies suggest it may affect gut microbiome composition and stimulate insulin secretion through sweet taste receptor activation in the gut, though clinical significance at typical dietary levels is debated.
