Is Lactulose Lactose Free?
AvoidNo. Lactulose is a synthetic sugar used to alleviate constipation. It contains lactose.
Lactulose and the Lactose Free Diet
Lactulose is a synthetic disaccharide sugar composed of galactose and fructose. It is not absorbed in the small intestine and instead moves to the colon, where it is broken down by bacteria to produce short-chain fatty acids. This process draws water into the bowel, softening stools and easing constipation. Although lactulose contains lactose, it is often prescribed safely for people with lactose intolerance as it does not impact blood glucose levels or trigger the usual symptoms associated with lactose due to its limited absorption and different metabolic pathway.
