What it is

Ace-K is an artificial sweetener that is about 200 times sweeter than table sugar. It is chemically synthesized and does not occur naturally. It is often used in combination with other sweeteners to provide a more sugar-like taste.

Why it's used

Ace-K is used to provide sweetness in foods and beverages with fewer calories than sugar. It is heat-stable, making it suitable for baked goods, and it does not break down over time, giving it a long shelf life. It is commonly found in diet sodas, sugar-free candies, and tabletop sweeteners.

Health notes

Ace-K is approved by the FDA as a food additive and is generally recognized as safe (GRAS). International bodies like JECFA and EFSA have also evaluated Ace-K. While generally considered safe at typical consumption levels, some studies have raised questions about its long-term effects, though evidence is mixed and ongoing. Regulatory agencies continue to monitor scientific research.

Allergen info

Ace-K is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
