What Scientists, Health Organizations & Regulators Say About Acesulfame Potassium (Ace-K)
Scientists, regulatory authorities and professional health organizations have extensively evaluated Ace-K. Explore statements and safety conclusions from leading organizations in the United States and internationally.
Professional Health & Nutrition Organizations
British Dietetic Association (2025)
In its 2025 joint position statement with the British Nutrition Foundation and Diabetes UK, the BDA states the following about low-and no-calorie sweeteners, including Ace-K
“When used to replace added sugars, LNCS can contribute to reducing free sugar intake, support weight management efforts, and aid in blood glucose control.”
American Heart Association (2024)
The American Heart Association’s statement on low-calorie sweeteners (LCS) including Ace-K
“Replacing sugary foods and drinks with sugar-free options containing LCS is one way to limit calories and achieve or maintain a healthy weight. Also, when used to replace food and drinks with added sugars, it can help people with diabetes manage blood glucose levels.”
The American Diabetes Association’s 2026 Standard of Care in Diabetes states the following on non-nutritive sweeteners including Ace-K
“Non-nutritive sweeteners do not appear to have a significant effect on glycemic management, and they can reduce overall calorie and carbohydrate intake as long as individuals are not compensating with additional calories from other food sources.” It also states, “Health care professionals should encourage reductions in foods and beverages with added sugars and promote reducing overall sugar intake and calories with or without the use of NNS.”
Regarding FDA-approved sweeteners, including Ace-K, the NCI states
“Six artificial sweeteners are approved by the US Food and Drug Administration (FDA) as food additives: saccharin, aspartame, acesulfame potassium (acesulfame-K, or Ace-K), sucralose, neotame, and advantame. Before approving these sweeteners, the FDA reviewed numerous safety studies that were conducted on each sweetener to identify possible health harms. The results of these studies showed no evidence that these sweeteners cause cancer or other harms in people.”
Academy of Nutrition and Dietetics (2012)
The Academy’s official position statement on nonnutritive sweeteners (NNS) including Ace- K
“Consumers can safely enjoy a range of nutritive sweeteners and nonnutritive sweeteners (NNS) when consumed within an eating plan that is guided by current federal nutrition recommendations, such as the Dietary Guidelines for Americans and the Dietary Reference Intakes, as well as individual health goals and personal preference.”
Government, Regulatory & Public Health Agencies
European Food Safety Authority – EFSA (2026)
In September, 2026, the European Food Safety Authority (EFSA) Food Additives and Flavorings (FAF) Panel examined all available research on Aspartame–Acesulfame Salt and its components (aspartame and ace-K), considering both short-term and long-term effects. The Panel found no safety concern at the reported uses and use levels for acesulfame K, aspartame, and the salt of aspartame-acesulfame. This follows EFSA’s 2025 re-evaluation of Ace-K. EFSA re-confirmed its safety and established the Acceptable Daily Intake at 15/mg/kg body weight.
Food Standards Australia New Zealand -FSANZ (2023)
FSANZ, together with the Ministry for Primary Industries in New Zealand recently conducted a review of all the intense sweeteners permitted for use in the Food Standards Code. A range of different sources of evidence were included such as sweetener use information and dietary exposure assessments.
Ace-K was first approved for use by Health Canada in 1994. It has undergone a premarket scientific safety assessment by the Food Directorate.
U.S. Food and Drug Administration – FDA (2003)
The FDA approved Ace-K for use in specific food and beverage categories in 1988 and in 2003 approved it as a general-purpose sweetener and flavor enhancer in food, except in meat and poultry, under certain conditions of use. The FDA reviewed more than 90 studies on acesulfame potassium that were designed to identify possible toxic effects, including studies on reproductive effects, carcinogenicity, and metabolism.
European Commission’s Scientific Committee on Food (2000)
In its re-evaluation of Ace-K, the European Commission’s Scientific Committee on Food confirmed the safety of acesulfame potassium and found that it showed no carcinogenic or mutagenic risk. The Acceptable Daily Intake of 0–9 mg/kg body weight/day was re-confirmed.
Joint FAO/WHO Expert Committee on Food Additives – JECFA (1990)
JECFA’s safety evaluation supports an established ADI for Ace-K. The Joint Expert Committee on Food Additives (JECFA), the scientific advisory body to the World Health Organization and the Food and Agriculture Organization of the United Nations, reviewed the available research on acesulfame K and concluded that it is safe. JECFA has also established an ADI of 15 mg/kg of body weight.
