Lactitol is a sugar alcohol sugar substitute produced from lactose. Lactitol is 40% as sweet as sucrose and contains 2.4 calories per gram.
Lactitol can have a laxative effect, causing gas, bloating, and diarrhea with as little as 10g of intake, but typically closer to 25g. It is used medically as a laxative. Lactitol has no effect on blood sugar and does not cause tooth decay.
Lactitol is unlikely to trigger symptoms in lactose intolerant individuals.
