The rows
1 no difference · 1 worse- CGrade CGas and diarrhoea in toddlers on daily xylitol solution · No difference
RCT · n 120 · 2007 · Children 6 to 36 months old in a practice-based research network (SCOR)
5 g three times a day or 7.5 g once a day · 3 months
Excessive gas or diarrhoea affected 10% to 27% of children on xylitol in a given month, which did not differ from placebo; withdrawals and visits for stomach complaints did not differ either. By month 3, about 90% accepted the solution easily or with minor difficulty.

RCT · n 64 · 2007 · Healthy students aged 18 to 24 at the University of Salford (UK)
Single doses of 20, 35 and 50 g · One test day per dose, 7-day washouts
50 g of xylitol increased nausea, bloating, rumbling, colic, watery stools and bowel movements compared with sucrose; 35 g also increased watery stools. At every dose xylitol caused more watery stools than erythritol.
