Sucralose (Splenda)
The question

Is Sucralose (Splenda) safe in protein bars?

CautionProtein bars

A chlorinated artificial sweetener approximately 600× sweeter than sugar. FDA and EFSA-approved with an ADI of 15 mg/kg body weight. The WHO issued a cautionary advisory in 2023 suggesting long-term consumption may have health implications not yet fully characterized. Short-term human studies show no significant effects on blood glucose or gut bacteria.

What the research flags

  • WHO 2023 advisory raises questions about long-term health implications
  • Some studies suggest possible gut microbiome effects at high doses [Inference]
  • Contains chlorine atoms — though not equivalent to chlorinated solvents
  • Long-term safety data still accumulating
