People who are sensitive to this ingredient may notice gi. Individual responses vary, so this symptom category does not replace the condition-specific rating above.
Editorial summary
This summary is editorial and is not part of the clinical review. Ratings above are unchanged.
What sucralose is
Sucralose is a high-intensity artificial sweetener. The FDA approved it for use in 15 food categories in 1998 and as a general-purpose sweetener in 1999, after reviewing more than 110 safety studies. The agency sets an acceptable daily intake of 5 milligrams per kilogram of body weight per day, which it illustrates as about 23 packets a day for a person weighing 60 kilograms.
Why it is rated with caution
Our rating note reflects research, including studies in mice, suggesting sucralose may affect gut bacteria. Findings are mixed, and evidence in people with autoimmune or digestive conditions is limited. A regulatory limit describes the amount considered safe for the general population over a lifetime, so the caution on this page is about individual tolerance and uncertainty, not about exceeding that limit.
Reading a label
Sucralose appears by name or by brand name. Products labeled sugar-free or diet often combine several sweeteners, and some add sugar alcohols that can cause digestive symptoms in their own right, so if a food bothers you, look at the full sweetener list instead of assuming the cause.
