Acesulfame K
What you need to know
Acesulfame potassium is an intense sweetener about 200 times sweeter than sugar. It is heat-stable, so it is used in baked and cooked products as well as drinks.
It is often blended with other sweeteners to round out the taste. Regulators in all major markets consider it safe at permitted levels.
It is not broken down by the body and passes through unchanged.
