Sorbitol
The question

Is Sorbitol safe in sugar-free candy?

CautionSugar-free candy

A sugar alcohol used in sugar-free gum, diabetic foods and toothpaste. Not systemically toxic, but it is incompletely absorbed, so higher intakes reliably cause gas, bloating and osmotic diarrhea — it is a classic FODMAP trigger.

What the research flags

  • Sorbitol is incompletely absorbed in the small intestine and its absorption is dose- and concentration-dependent; malabsorbed sorbitol is fermented by colonic bacteria, so excess intake commonly causes flatulence, abdominal discomfort and osmotic diarrhea (Montalto et al. review of sorbitol malabsorption)
  • As a FODMAP polyol, sorbitol can provoke or worsen symptoms in people with irritable bowel syndrome; reviews note that symptom severity after a sugar/polyol challenge is greater in IBS patients than in healthy controls (Fernandez-Banares, Nutrients 2022 review of carbohydrate maldigestion)
