Are there any side effects of xylitol consumption?
Clinical studies have demonstrated that xylitol consumption of up to 70 grams per day can be tolerated in diabetic patients, and up to 200 grams per day in adapted normal subjects without side effects. Some sensitive individuals may experience a slight laxative effect with the higher doses. As the enzymes that metabolise xylitol adapt to consumption over time, if this effect occurs it is usually transient (5). In practice, xylitol consumption would be not expected to exceed 30-50 grams per day.
