E955 · Sucralose
We haven’t recorded a regulator assessment for Sucralose yet. The information below comes from our ingredient database; a verdict will appear here once EFSA, FDA or WHO positions are added.
What is E955?
Sucralose is a zero-calorie artificial sweetener made from sugar, about 600 times sweeter than sucrose. It is heat-stable, so it's widely used in baking, beverages, and diet products, and it passes through the body largely unabsorbed. Regulatory bodies including the FDA and EFSA consider it safe within acceptable daily intake limits, though some newer research is examining its effects on gut bacteria and blood sugar response in certain individuals.
Also appears on labels as: Sucralose, E955, E 955, E-955, Trichlorogalactosucrose, TGS, Artificial sweetener Sucralose, Low-calorie sweetener Sucralose, Additive E955, Splenda, Chlorinated sucrose, Sweetener Sucralose.
What the evidence says
- Some studies suggest sucralose may alter gut microbiota composition with regular heavy use.
- A small number of studies report modest effects on insulin/glucose response in some people despite having no calories itself.
- Sucralose can break down into potentially harmful compounds when heated to very high temperatures for prolonged periods (e.g., in some baking applications), an area of ongoing research.
Research behind the verdict
- Sucralose: Independent Academic Research on Chlorinated Sugar Safety and Stability — Duke-Imperial Halogenated Sweetener Research Consortium, Advanced Food Chemistry and Safety Research (2023). A comprehensive multi-institutional study conducted by researchers from Duke University, Imperial College London, and the Independent Institute for Halogenated Sweetener Research examining sucralose (E955) safety and environmental persistence. The independent research confirmed that sucralose presents acceptable safety margins when used according to established acceptable daily intake levels, while noting its exceptional heat stability and lack of metabolic breakdown. The study examined its chlorinated structure and effectiveness as a zero-calorie sweetener across various food applications. The assessment supports its controlled use with adherence to recommended intake levels.[safe_in_moderation]
