Aspartame is safe. After a comprehensive and rigorous review, the World Health Organization (WHO) found aspartame is safe and ‘no sufficient reason to change the previously established acceptable daily intake.’ This strong conclusion reinforces the position of the Food & Drug Administration (FDA) and food safety authorities from more than 90 countries. 

Don’t just take our word for it. Read what food safety authorities and experts all over the world are saying:


United States Food and Drug Administration,

“Aspartame is one of the most studied food additives in the human food supply. FDA scientists do not have safety concerns when aspartame is used under the approved conditions.”

United Kingdom Food Standards Agency, Science Media Centre:

“JECFA’s report supports the Food Standards Agency’s view that aspartame is safe to consume at current permitted use levels.”

Kingdom of Saudi Arabia Saudi Food and Drug Authority, Al Madina:

Aspartame has been used for more than 40 years and is found in more than six thousand products in various countries of the world, and there is no evidence or scientific evidence proving the danger of its consumption.

Food Standards Australia New Zealand,

“This is good news for consumers in Australia and New Zealand who can be assured our food standards for aspartame align with international benchmarks. The JECFA conclusion is in line with numerous international studies which have found aspartame to be safe.”

Health Canada,

“…scientific advisory bodies such as the Scientific Committee for Food of the European Community, and the Joint Expert Committee on Food Additives (JECFA) of the United Nations Food and Agriculture Organization and World Health Organization have reviewed all the available safety studies and have found aspartame to be safe. More than ninety countries world-wide, including the United States, countries of the European Union, and Australia and New Zealand, have also reviewed aspartame and found it to be safe for human consumption and allow its use in various foods.”

Diego Varela, Chilean Agency for Food Safety and Quality Executive Secretary and Vice-Chair of the WHO/FAO Codex Alimentarius Commission, Twitter:

“JECFA notes that there is insufficient evidence to change the previously established Acceptable Daily Intake (ADI)… Therefore, the Committee reaffirmed that the consumption of a daily amount that is within this limit is safe.”

China National Food Safety Risk Assessment Center,

“The National Food Safety Risk Assessment Center (CFSA) and the National Cancer Center reviewed the latest assessment results of JECFA and the consumption of Chinese residents to conduct safety assessment, and confirm that aspartame can be used in accordance with China's current standards and specifications to ensure safety.”

German Federal Institute for Risk Assessment, BfR:

"So far, the evaluation panels have come to the conclusion that there are no health concerns provided the acceptable daily intake (ADI) of 40 mg/kg body weight and day is not exceeded.”

Austrian Agency for Health and Food Safety, AGES:

"WHO/JECFA findings that 'there is no convincing evidence that aspartame has adverse effects' [...] are in line with the conclusions of [the European Food Safety Authority] 2013 assessment on aspartame."

Vlastimil Valk, Czechia Minister of Health,

“It’s not even that there is a huge risk, but it’s that even a minimal risk doesn’t occur, that’s why we’re always much more careful and strict. In practical terms, it will mean absolutely nothing for the Czech citizen.”

The Swedish Food Agency, Livsmedelsverket:

"...there are no known risks of eating aspartame."

Belgian Federal Public Service Health, Food Chain Safety and Environment: Het Nieuwsblad:

"There is, therefore, no reason for JECFA to change the acceptable daily intake of 40 mg of aspartame per kilogram of body weight per day. The consumption of aspartame within this limit is, therefore, still considered safe."

Ministry of Health of Israel, Maariv:

"There is currently no warning not to consume beverages containing aspartame."

Republic of Korea Ministry of Food and Drug Safety, Yonhap News Agency:

“South Korea’s Ministry of Food and Drug Safety said it has decided to retain the country’s daily intake level of 40 mg/kg, considering the JECFA’s recommendation and the aspartame consumption of South Korean people.”

Food Safety Authority of Ireland,

“Aspartame has also been evaluated by numerous scientific committees internationally over many years and has been found to be safe. It Is authorized for human consumption in many countries following thorough safety assessments.”

Japan Food Safety Commission,

“The Japanese Food Safety Commission referenced long-standing positive research from agencies including the European Food Safety Authority, which said there are no safety concerns.”

Mari Reinik, Deputy Director of the Estonia National Centre for Laboratory Research and Risk Assessment, novaator:

"Since the acceptable dose has not been changed based on current research, it does not give a direct signal to change people's behavior."

Portugal Economic and Food Safety Authority (ASAE),

"The ASAE Scientific Council understand that there is no new data that would allow changing the EFSA recommendations regarding the use of aspartame as a sweetener."

Brazil Health Regulatory Agency (Anvisa),

“There is consensus among several international committees considering aspartame safe, when consumed within the acceptable daily intake.”

Oman Food Safety and Quality Center, Twitter:

Oman authorities reaffirmed the conclusion from JECFA that aspartame is safe, saying of the acceptable daily limit established by JECFA that "it is not easy to reach this quantity per one day."

Jordan Food and Drug Administration (JDFA), Watana News:

“JFDA clarified that the classification of aspartame as a potential carcinogen indicates a lack of definitive scientific evidence proving its link to cancer."

Thai Food and Drug Administration,

“Pharmacist Lertchai Lertwut, Deputy Secretary-General of the [Thai] Food and Drug Administration revealed that the FDA there is an inspection and assessment of the safety of the use of aspartame […] consumers are requested to be confident that the sweeteners that are approved by the [Thai] FDA and supervise their use in accordance with the Ministry of Public Health's announcement are safe.”

Indonesia Food and Drug Authority (IFDA):

"The IFDA still permits the use of aspartame. Currently the regulations for aspartame-made sweetener food additives are still within the maximum limit."

Dr. Moez Sanaa, World Health Organization, The Times UK:

“JECA had ‘concluded that the evidence of an association between aspartame consumption and cancer in humans is not convincing.”

Dan Glickman, Former U.S. Department of Agriculture Secretary, Twitter:

“Aspartame, a sugar substitute in some foods and beverages, found safe by FDA, helpful in lowering sugar consumption.”

Scott Gottlieb, Former U.S. Food and Drug Administration Commissioner, CNBC:

"I don't have concerns here. We looked at this very closely while I was at the FDA, the FDA has looked at this very closely since - there have been exhaustive studies here that haven't demonstrated a risk."

Dr. Arnold Baskies, Past Chair of the National Board of Directors of the American Cancer Society, PR Newswire:

"The WHO Joint Expert Committee on Food Additives' (JECFA) review says that aspartame is safe for human consumption."

Alex Azar, Former U.S. Department of Health and Human Services Secretary, Twitter:

"The FDA once again affirmed the safety of aspartame, as have many other food regulatory bodies across the world.  The FDA is the gold standard in ensuring the safety of America's food supply. That’s good enough for me and my family."

Dr. Richard Carmona, Former U.S. Surgeon General, KRIV-TV:

“There’s over a half a century hundreds of research papers, hundreds of scientists, who have already commented on this and found that there’s no association with cancer or any disease.”

Donna Shalala, Former U.S. Department of Health and Human Services Secretary, PR Newswire:

"There's over a half a century, hundreds of research papers, hundreds of scientists, who have already commented on this and found that there's no association with cancer or any disease."

Dr. Claire Knight, Senior Health Information Manager at Cancer Research UK, The Times UK:

“There is no convincing evidence that it causes cancer in humans and people shouldn’t be worried about getting cancer from aspartame in food and drink.”  


The safety of our products is the highest priority for our industry. The purpose and expertise of food safety agencies is to ensure safety over time. WHO has done this again, comprehensively and rigorously, with aspartame. With more than 40 years of science and this definitive conclusion from the WHO, people can move forward with confidence that aspartame is a safe choice, especially for anyone looking to reduce sugar and calories in their diets.
