European regulators confirm sucralose safety despite earlier DNA damage study
European authorities concluded in September 2026 that the artificial sweetener Splenda remains safe under its authorized uses following a review of recent research.
Original Study Findings
A 2023 investigation identified sucralose-6-acetate as a chemical impurity found in some commercial sweetener samples. Researchers reported that this specific compound damaged DNA and disrupted models of the intestinal lining in laboratory experiments. The study noted concentrations of up to 0.67% for this substance in certain batches.
Regulatory Review Process
Subsequent testing challenged the idea that this chemical necessarily forms during human digestion. A major European safety assessment was conducted to evaluate the overall risk associated with ordinary consumption. These reviews added important context to the initial alarming picture presented by the lab results.
Final Safety Conclusion
European regulators determined that the sweetener remains safe for its currently authorized uses as of 2026. The original experiments did not establish that standard sucralose consumption damages DNA in people. Later findings have complicated the earlier concerns regarding the product's safety profile.
