Research evaluates genetic toxicity concerns regarding sucralose and related byproduct

ScienceDaily reports that early laboratory toxicity findings contrast with European safety reviews and subsequent genetic testing.

The short version

  • A 2023 study found that sucralose-6-acetate damaged DNA in cell tests and disrupted an intestinal lining model.[ScienceDaily]
  • Scientists detected the chemical at levels up to 0.67% across analyzed commercial sucralose samples.[ScienceDaily]
  • In February 2026, the European Food Safety Authority concluded sucralose food additive use raises no genotoxicity concern.[ScienceDaily]
  • An August 2026 study evaluating commercial-grade sucralose found negative results in most mutation and chromosome damage tests.[ScienceDaily]

Key facts

  • A 2023 study determined that sucralose-6-acetate damaged DNA in laboratory experiments and impaired an intestinal lining model.[ScienceDaily]
  • Sucralose-6-acetate was detected at concentrations as high as 0.67% within tested commercial sucralose samples.[ScienceDaily]
  • The European Food Safety Authority reassessed sucralose in February 2026 and concluded its food additive use presented no genotoxicity concerns.[ScienceDaily]
  • An August 2026 study in Food and Chemical Toxicology reported negative results in most mutation and chromosome damage assays on commercial sucralose.[ScienceDaily]

What remains uncertain

  • Conflicting findings exist between the 2023 study showing DNA damage from sucralose-6-acetate and the 2026 safety evaluations finding no genotoxicity.[ScienceDaily]
